Hotwire DSL System Description  
1
What is the Hotwire DSL System?  
The Hotwire® Digital Subscriber Line (DSL) system is a set of central site products  
that terminate and consolidate packet data traffic from many customers in a  
serving area. The DSL card(s) then forwards the traffic to one or more network  
access provider networks.  
High-speed Internet and intranet access is either bridged or routed on the DSL line  
cards and multiplexed over backbone networks. By enabling very high speeds  
using DSL technology and concentrating Internet Protocol (IP) traffic, greater  
performance is realized.  
In addition, the Hotwire GranDSLAM, with an endpoint such as a 6310 Multiple  
Virtual Lines (MVL®) modem and 5620 Remote Termination Unit (RTU), can  
co-exist with plain old telephone service (POTS) over the same copper telephone  
line, providing simultaneous usage of POTS and digital applications. That is, the  
optional central office (CO) POTS splitter and customer premises POTS filter allow  
simultaneous voice and data connections over a standard telephone line.

1. Hotwire DSL System Description  
Hotwire DSL System Components  
The DSL system consists of a chassis that houses a Management  
Communications Controller (MCC) card and up to 18 DSL cards. The Hotwire  
8620 and 8820 GranDSLAM chassis can also house a Shelf Concentration  
Module (SCM) card, depending on the application. See the Hotwire Shelf  
Concentration Module (SCM) Card User’s Guide for more information.  
NOTE:  
All references to MCC cards in this document refer to the MCC, MCP and  
MCC Plus cards, unless specifically noted otherwise.

1. Hotwire DSL System Description  
SCM Card  
The Shelf Concentration Module (SCM) card aggregates DSL traffic for the  
Hotwire 8620 and 8820 and GranDSLAM chassis. The operation and configuration  
of this card is not within the scope of this document. See the Hotwire Shelf  
Concentration Module (SCM) Card User’s Guide for more information.  
DSL Chassis  
DSL cards can reside in four types of chassis:  
8600/8610 DSLAM  
A 3-slot chassis with Ethernet uplink. The stackable design provides for up to  
six chassis to share management access through a single MCC card, which in  
turn allows an additional slot for a DSL card in each of up to five additional  
chassis. The 8610 DSLAM chassis offers the same benefits as the  
8600 chassis, with the added capability of accepting high-density DSL cards

information is displayed. This is also the portion of the screen on which fields  
requiring input are displayed. However, you cannot enter values for the fields  
in this portion of the screen. You must enter field values in the Input Line at the  
bottom of the screen (see Step 3).  
3. Input Line is the area of the screen below the line where you are prompted to  
enter values for the specific field that is highlighted on the screen.  
For example, in the General Interfaces screen above, the Interface Name field  
is highlighted. If you want to modify an interface, you must enter the Interface  
Name at the Input Interface Name:prompt at the bottom of the screen.

2. Hotwire Menus and Screens  
Levels of Access  
There are two levels of privileges on the Hotwire DSL system. Your user accounts  
can be configured with a user name, password, and privilege of:  
Administrator. The Administrator has complete read/write access to the DSL  
system. With Administrator permission, you can set specific parameters and  
variables to configure cards, ports, interfaces, VNID bridging, and endpoint  
selection.  
Operator. The Operator has read-only access and can view configuration  
information and monitor performance but has no configuration menu access or  
modification permission.  
The default access is no login and password with Administrator status. To provide  
login security to the DSL system, user accounts must be configured.  
NOTE:  
There must be at least one Administrator configured in order to have system  
security.  
For information on configuring user accounts, see the Hotwire Management  
Communications Controller (MCC) Card, IP Conservative, User’s Guide.  
User Login Screen  
You can log in to the Hotwire DSL system using either a local VT100-compatible  
terminal or a remote Telnet connection. However, the Hotwire DSL system accepts  
only one login session at a time.  
NOTE:  
The User Login screen only appears if one or more users have been defined  
on the MCC.  
At the User Login screen, enter your login ID and password. You must wait until  
your login is verified, anywhere from two seconds to 12 minutes. If you have  
RADIUS Authentication, this verification takes some time while each RADIUS  
server is contacted one at a time.  
If you are denied access during a Telnet session, the session stops and an error is  
logged. If you are using a console, return to the User Login screen.  
NOTE:  
If you forget your password, contact your Technical Service Center. Have the  
serial number of the MCC card available, and the service representative will  
provide you with a password.

2. Hotwire Menus and Screens  
NOTE:  
The login ID and password are case-sensitive; that is, the system recognizes  
both upper- and lowercase letters. For example, if you enter your user name  
and password information in uppercase letters and your assigned user name  
and password are in upper- and lowercase letters, the system will not let you  
log in.  
After entering your login ID and password, the system displays the Hotwire  
Chassis Main Menu.

DSL Card Configuration  
3
Overview  
This chapter describes configuration options on the DSL card. Use these options  
to customize your applications. For information on customizing the MCC card, see  
the Hotwire Management Communications Controller (MCC) Card, IP  
Conservative, User’s Guide.  
Naming Conventions  
Special naming conventions exist for the Port Name and Interface Name fields.  
Port Name – Identifies a physical port. It consists of a family name (such as  
dsl for a DSL card, eth for Ethernet, or sar for SAR), and a port number. The  
port number can range from 1–4 for 4-port cards such as the 8510 RADSL  
card, 1–12 for 12-port cards such as the 8312 ReachDSL/MVL card, or 1–24  
for 24-port cards such as the 8343 SDSL card. See the following example:  
dsl4  
where:  
dsl = Family Name (dsl, eth or sar)  
4 = Port Number (for example, Port 4)  
Interface Name – Identifies a logical connection. It consists of a family name  
and a port number (same as the port name), followed by a number identifying  
the drop on which the connection is located (for those networks consisting of  
multiple drops on a line). Currently, the drop number is limited to 1 on all  
screens, except for Block Error Rate Test (D-E) on the 8314 ReachDSL/MVL  
card. See the following example:  
dsl12:1  
where:  
dsl = Family Name (dsl or eth)  
12 = Port Number (for example, Port 12)  
1 = Multidrop Number (currently, only 1 is allowed)

3. DSL Card Configuration  
Configuring Subnet Addressing  
To define a subnet entry, the IP address has to be entered as the lower boundary  
address of the subnet. Otherwise, only a host entry can be configured.  
For example, a subnet with a mask of 255.255.255.192 requires one of the  
following IP addresses, where xxx = any IP address:  
xxx.xxx.xxx.0  
xxx.xxx.xxx.64  
xxx.xxx.xxx.128  
xxx.xxx.xxx.192  
Configuring Subnet Masks  
After the IP address is entered, a default subnet mask is displayed. The default  
subnet mask is based on the IP address entered and can be changed.  
If the IP Address entered is . . .  
xxx.xxx.xxx.0  
Then the Default Subnet Mask is . . .  
255.255.255.0  
xxx.xxx.0.0  
255.255.0.0  
xxx.0.0.0  
255.0.0.0  
xxx.xxx.xxx.xxx  
255.255.255.255  
To configure the DSL card, a valid subnet must be used. When a Host entry is  
input, any valid IP address results in a subnet mask of 255.255.255.255.  
When a Subnet entry is entered, the valid subnet mask is based on the IP address  
entered. A valid subnet mask must be in one of the following formats:  
255.0.0.0  
255.nnn.0.0  
255.255.nnn.0  
255.255.255.nnn  
Where nnn must be: 0, 128, 192, 224, 240, 248, 252, 254.

3. DSL Card Configuration  
Domain Types  
To monitor and control the overall system, the Hotwire Access Network should be  
partitioned into two distinct domains:  
Service domain(s) (Layer 2, MAC Bridging)  
Management domain (Layer 3, IP Routing)  
Service Domain  
A service (or data) domain is comprised of all clients and servers (grouped  
physically or virtually) that communicate across a common WAN or LAN  
connection for Internet or intranet access. This is the Layer 2 bridging domain of  
the NSP. The Access Node cards and the Service Nodes are the Hotwire  
components of this domain. The service domain also encompasses an NSP and  
all end-user systems that subscribe to that NSP.  
Management Domain  
The primary function of the management domain is monitoring and configuring the  
DSL cards and service domains served by the DSLAM. The management domain  
should reside in a mutually exclusive domain from that of the service (data)  
domain(s). The MCC card functions as a service router and is the primary tool for  
configuring and diagnosing the management domain.  
It is recommended that the management domain reside in a separate domain from  
the service domain(s) for security purposes and to improve download  
performance.  
Minimum Configuration  
The minimum configuration of the DSL port card differs, depending on the type of  
SN used.  
Minimum Configuration When Using the 5620, 6310, or 6350 SN  
When using either the 5620, 6310, or 6350 SN, the DSL port card is in control of  
the connection. At a minimum, you must configure the following:  
VNIDs on a DSL card (see Configuring VNID(s) on a DSL Card on page 3-20)  
The active VNID and the Next Hop Router on each DSL port/interface (see  
Configuring the Active VNID and the Next Hop Router on each DSL  
Port/Interface on page 3-22) when using DHCP  
Static users (see Configuring Static Users on page 3-23) if you have static  
users on your network, fixed addresses, or subnets

3. DSL Card Configuration  
Minimum Configuration When Using the DSL Router  
When using the DSL Router as the SN, the DSL Router is in control of the  
connection. At a minimum, you must configure the following:  
VNIDs on a DSL card (see Configuring VNID(s) on a DSL Card on page 3-20)  
Activate the VNID Binding Table to the port (see Configuring the Active VNID  
and the Next Hop Router on each DSL Port/Interface on page 3-22), except  
when using a DSL card with an ATM Network interface in Standard mode.  
NOTE:  
The default minimum configuration for a DSL card with an ATM Network  
interface is a valid configuration.  
DSL Configuration Card Screens  
Use the system information submenu of the Card screens to configure basic DSL  
card-level information.  
NOTES:  
— Only a user who logs in to the Hotwire DSL system with Administrator  
permission can configure the DSL card.  
— You cannot upload a configuration from a 4-port MVL card, then download  
it to an 8312 12-port ReachDSL/MVL card.

Allows configuration of the operational and alarm parameters of the IDSL ports on the  
IDSL 8303/8304 cards. Each IDSL port is configured separately.  
NOTE: For other types of port cards, refer to the appropriate section in this table.  
Action – Edit to configure DSL ports. Reset to reset port and activate changes.  
Port Name – Enter 1–24.  
State – Port state. This field is read-only. Displays Port Enabled, Port Not Enabled (port is  
performing a reset, or has never been made active), or Port Not Selected (a port number  
has not been specified for display). (Default = Port Not Selected).  
SN Type – Model number of the service node (Default = 6301R2). For Model 8303/8304  
IDSL cards, SN type is Paradyne 6301R2, Paradyne 6302R2, or None (R2 indicates  
Release 2 or greater). Select None when the port is connected to a network timing source  
only and no endpoint is attached. Use Ctrl-v for a pop-up menu with available selections.  
Line Code – 2B1Q. (This field is read-only.)  
Data Rate – 144/128/64 (Default = 144 kbps).  
Link Encapsulation – Determines the protocol to be run on the selected port  
(Default = EtherHDLC). Use Ctrl-v for a pop-up menu with available selections. Choose  
from the following:  
– EtherHDLC for IP packet applications  
– FUNI/MPOA for 8304 cards only  
NOTE: If you select FUNI/MPOA, the endpoint must be configured for routing only,  
otherwise the line will fail to come up and a SYSLOG message will be generated.  
Channel for 64 Kbps – B1/B2 (Default = B1). Valid channel for 64 kbps operation.  
Transceiver Mode – Enter NT (Network Termination) or LT (Line Termination)  
(Default = LT). NT is used for timing while LT is used for data. One and only one IDSL port  
in each chassis must be dedicated as NT and connected to the appropriate ISDN timing  
source in the CO. This timing is then distributed to all other IDSL ports in the chassis.  
Only the first four ports on the card can be set to NT.  
For timing: An IDSL circuit must be synchronized with the Digital Carrier System (the  
Digital Loop Carrier or DLC). The port you select for NT mode will be used to terminate a  
connection to an LT dedicated for system clock use. This NT port will probably not be  
used for data, but will derive the 2.048 Mhz system clock from the connection and  
distribute this timing to the other 23 IDSL ports on this card, and to other IDSL port cards  
via the backplane clock circuit. Once you have set one of the ports on the IDSL card for  
NT mode, use the IDSL Clock Configuration screen (A-G-B) on the MCP card to  
configure one of the clock circuits on the backplane to receive its timing from the IDSL  
port you just configured. To do this, set the Clock Configuration for  
NET_CLOCK1/NET_CLOCK2 field to 3 for Drive System Clock).  
NOTE: If the NT port loses the connection and the timing source fails, all IDSL loops  
on the chassis may lose data (denoted by Major Alarm and SNMP trap). For  
redundancy, you may wish to dedicate an additional port on another IDSL card in the  
chassis as a spare timing source and leave the port it in LT mode. In case of failure,  
this secondary timing port can be enabled remotely by changing the status of the  
primary timing port to LT and the secondary port to NT. Be aware that the  
NET_CLOCK1 and NET_CLOCK2 options must be configured correctly on the MCC  
card. See the Hotwire Management Communications Controller (MCC) Card, IP  
Conservative, User’s Guide for more information.

3. DSL Card Configuration  
Configuring VNID(s) on a DSL Card  
A VNID is a Virtual Network Identifier known as the 802.1Q tag between port cards  
with an Ethernet network interface and the Interworking Packet Concentrator  
(IPC). This directs traffic between the ISP and the end user. Tagging occurs  
between the DSL card and the IPC to ensure that data is sent to the correct  
location. This helps to ensure that data is not broadcast to all ports when Mux  
forwarding is enabled. To enable VNID tagging for port cards with an Ethernet  
network interface, you must first ensure that matching groups are configured on  
the IPC.  
VNID configuration is required on DSL port cards when the port card is  
operating in the VNET-Bridged mode. However, when a DSL port card with an  
ATM Network interface is operating in Standard mode, no VNID configuration  
is required.  
802.1Q VLANs must be configured on the IPC when a DSL port card with an  
Ethernet Network interface is used. However, 802.1Q VLANs are not required  
when a DSL port card with an ATM Network interface is used in conjunction  
with an SCM card in the Hotwire 8820 GranDSLAM.  
Before configuring VNIDs, you must enable VNID tagging (A-E-A), then reset the  
card.  
NOTE:  
Before configuring VNIDs, determine what type of endpoints are attached.  
Desired DSL port card configuration settings may differ, depending on the SN  
attached.  
Procedure  
To configure at least one VNID for this DSL card from the Hotwire – DSL Card  
menu:  
1. Follow this menu selection sequence:  
Configuration → Bridge → Card VNID Table (A-E-B)  
2. Type 0 or press Enter at the Item Number(0 to add new item):  
prompt.  
3. Enter the VNID (2–4000 for port cards with an Ethernet Network interface or  
2–255 for port cards with an ATM Network interface) at the Enter VNID ID  
prompt.  
4. Enter enabled at the Enabled/Disabled:prompt in the Mux Fwd field.  
(Default = enabled.)  
5. Enter disabled at the Enabled/Disabled:prompt in the IP Filter field.  
(Default = disabled.)

6. For all SNs except the DSL Router, enter enabled at the  
Enabled/Disabled:prompt in the IP Scoping field. (Default = enabled.)  
You can also enable IP Scoping on port cards with a DSL Router SN except  
under certain conditions. See Exception When Using a DSL Router.  
7. If desired, enter an ISP domain name at the Domain Name:prompt  
(30 characters maximum).  
Example: If entering a VNID for XYZ Company, enter XYZ as the Domain  
Name.  
8. Enter yes at the yes/no:prompt to save your changes.  
Changing the Existing VNIDs or VNID Attributes  
If a new VNID is activated on the DSL port, relocate all clients to the new VNID  
(with user’s approval). Otherwise, delete all clients associated with the old VNID.  
Also, if IP Scoping is disabled for the new VNID but was enabled for the old VNID,  
delete all dynamic client entries (along with their associated ARP and MAC  
entries).  
Exception When Using a DSL Router  
This section presents an example of an exception when IP Scoping must be  
disabled when using a DSL Router. IP Scoping on the port card must be disabled  
if the DHCP relay capability on the DSL Router is enabled, and the IP addressing  
scheme allows the core device at the access provider’s location to ARP directly for  
the client behind the DSL Router. In the figure below, the Cisco Router ARPs  
directly for the client PC. Therefore, IP Scoping must be disabled on the port card  
for proper data communication.

3. DSL Card Configuration  
Configuring the Active VNID and the Next Hop Router on each DSL Port/Interface  
You can configure multiple VNIDs with different next hop routers with one active  
VNID configured per port/interface. For more information about the fields listed in  
this procedure, see Table 3-4, Bridge Options.  
Procedure  
To configure the active VNID on each DSL port from the Hotwire – DSL menu:  
1. Follow this menu selection sequence:  
Configuration → Bridge → VNID Binding Table (A-E-C)  
2. Type 0 or press Enter at the Item # (0 to add new item):prompt.  
3. Enter the DSL interface. Enter 1 through 4 for 4-port DSL cards, 1 through 12  
for 12-port DSL cards, or 1 through 24 for 24-port DSL cards. Only one  
interface per port is allowed.  
4. Enter the number of the VNID to be assigned to this port (2 through 4000) at  
the Active VNID prompt. For DSL port cards with an Ethernet network  
interface, if you want a VNID that spans several DSL cards, you must specify  
the same VNID number across all cards. For DSL port cards with an ATM  
network interface, a VNID can span across all the ports of the same card, but  
cannot span multiple cards. A pop-up menu of active VNIDs is available by  
typing Ctrl-v in the Active VNID column.  
5. Enter the IP address of the Next Hop Router (0–255 for each octet) at the  
Default NHRprompt, if desired. Enter a space to delete the current NHR  
entry. This is an optional field. However, an NHR is required when IP Scoping  
is enabled.  
NOTE:  
Administrator-level permission is required to enter a Default NHR.  
6. Type yes at the Save changes? prompt to save your changes.  
NOTE:  
VNID configuration is not required in Standard mode.

3. DSL Card Configuration  
Configuring Static Users  
You must perform this procedure if you have static users unless you are using a  
DSL Router and operating in Standard mode set on SCM card. You can configure  
up to 32 host entries or subnet entries per DSL interface. For more information  
about the fields listed in this procedure, see Table 3-4, Bridge Options.  
NOTE:  
Do not assign the same subnet to multiple ports.  
Procedure  
From the Hotwire – DSL menu:  
1. Follow this menu selection sequence:  
Configuration → Bridge → Client VNID Table (A-E-E)  
2. Enter the name of the interface at the DSL Interface Name:prompt. Enter  
1 through 4 for 4-port DSL cards, 1 through 12 for 12-port DSL cards, or 1  
through 24 for 24-port DSL cards.  
3. Type 0 or press Enter at the User: prompt.  
4. Enter the IP Address of this user at the Enter client IP address  
(nnn.nnn.nnn.nnn): prompt. Enter the IP addresses of all clients behind  
the nonrouter SN if IP Scoping or IP Filtering is enabled.  
If using a DSL Router, enter its IP address. Also enter the IP address of all  
clients behind the DSL Router if IP Filtering is enabled.  
5. Enter the subnet mask at the Enter Subnet Mask (nnn.nnn.nnn.nnn):  
prompt.  
6. When using a subnet with a nonrouter SN, enter the IP address of the next  
hop router for this client at the Enter IP address of next hop router  
(nnn.nnn.nnn.nnn): prompt. The address used must be part of the  
subnet that is attached to the nonrouter SN. When using a DSL Router, enter  
the IP address of the NHR.  
7. Enter the VNID for this user at the Input VNID ID: prompt. If VNID tagging  
is disabled, Noneappears in this field.  
8. Enter yes at the yes/no:prompt to save your changes.  
NOTE:  
Static IP address configuration is not required when the DSL port is  
configured in Standard mode.

3. DSL Card Configuration  
Table 3-4. Bridge Options (1 of 5)  
General (General Bridge Parameters)  
A-E-A  
Gives the user the ability to configure general bridge parameters. You must reset the card  
for your changes to take effect.  
Complete Entry Timeout – Enter the bridge aging timeout (10–1,000,000 seconds)  
(Default = 300). This option determines how long the system waits before posting an ARP  
entry as timed out.  
Complete Entry Cleanup Interval – Enter the bridge aging cleanup interval in seconds.  
This is typically set to 1/2 of the Complete Entry Timeout setting. (Default = 150). This  
option determines how often the system removes timed-out entries from the ARP cache.  
MAC Learning in Auto VNID Mode – For DSL cards with an ATM network interface only.  
Enable/Disable (Default = Disable). Enables the bridge to learn the MAC addresses of  
clients (useful for troubleshooting but reduces packet throughput on bridge). If you  
change this setting, you must reset the card before the change will take effect.  
VNID Tagging – For DSL cards with an Ethernet network interface only. Enable/Disable  
VNID tagging on the card (Default = Disable). When you enable tagging, you are  
assuming that the other end of the connection supports 802.1Q tagging.

3. DSL Card Configuration  
Table 3-4. Bridge Options (2 of 5)  
Card VNID Table  
A-E-B  
Gives the user the ability to configure Virtual Network IDs (VNIDs) for the entire card.  
There are a maximum of 16 entries per 4- and 12-port cards, or 32 entries per 24-port  
card. If VNID Tagging is disabled (see General (General Bridge Parameters) A-E-A on  
page 3-24), only one VNID appears on this screen to be configured.  
NOTE: Enabled fields display En. Disabled fields display blank.  
Item – Enter 0 (zero) to add a new record. Or, enter 1–16 (for 4- and 12-port cards) or  
1–32 (for 24-port cards) to display configured information for that item number.  
VNID – Enter a VNID between 2–4000 for DSL cards with an Ethernet network interface,  
or 2–255 for DSL cards with an ATM network interface (Default = NULL). A space deletes  
the current VNID entry and the rest of the values in this row. Do not enter a space if a  
message is displayed indicating that any port has this as the active VNID.  
Mux Fwd – Enable/blank (disable) (Default = Enable).  
When Mux Fwd is enabled, all upstream traffic is sent out through the 10BaseT  
interface on port cards with an Ethernet network interface or through the SAR  
interface on port cards with an ATM network interface. Forwarding restrictions are  
set by the other parameters on the screen.  
When Mux Fwd is disabled, the DSL card forwards traffic based on a destination  
MAC address.  
Either enabled or disabled, traffic is forwarded on ports having the same VNID  
designation.  
IP Filter – Enable/blank (disable) (Default = Disable).  
When IP filtering is enabled, the DSL card looks at IP traffic from the subscriber to  
authenticate the source IP address.  
When IP filtering is disabled, no source authentication check is performed.  
IP Scoping – Enable/blank (disable) (Default = Enable). If Mux Fwd is set to Disable,  
then IP Scoping is set to Disable.  
When IP Scoping is enabled, Dynamic Host Configuration Protocol (DHCP)  
scoping is also enabled and the DSL card intercepts IP ARP and DHCP transaction  
messages.  
When IP Scoping is disabled, DHCP client entries are not added to the Client table  
and non-IP traffic is forwarded. If IP Scoping is enabled, non-IP traffic is not  
forwarded.  
DHCP clients in one VNID domain can only obtain the IP addresses in one IP subnet, and  
the core router’s primary IP address is part of that subnet. As a result, DHCP clients in  
one VNID domain cannot be in different subnets. If the DHCP scope falls in a statically  
configured subnet, all the dynamic clients will get an IP address in that static subnet. This  
assumes that the core router is configured for DHCP relay.  
Set this option to Disable if you are using a DSL Router.  
VNID Auth – Enter a VNID number. When VNID Auth is enabled, the DSL port card  
authenticates the traffic from the DSL Router.  
Domain Name – Enter the domain name of the Internet Service Provider (ISP)  
(30 characters maximum).

The Add or Edit selection takes you to the IP FIlter Configuration screen. When you exit  
that screen, you return to the IP Filters screen.  
NOTE: Deleting the filter deletes all rules associated with that filter.  
IP Filter (Filter Rule Configuration screen)  
(A-G-A)  
Allows you to build multiple rules for an IP filter. A filter consists of a set of rules applied to  
a specific interface to indicate whether a packet received or sent out of that interface is  
forwarded or discarded. You can add, edit, or delete filter rules within a named set.  
A filter works by successively applying the rules to the information obtained from the  
packet header until a match is found. The filter then performs the action specified by the  
rule on that packet, which forwards or discards the packet. If all the rules are searched  
and no match is found, the configured default filter action is executed.  
Host rules have higher precedence than network rules. Rules apply to the  
source/destination IP address, source/destination port number, and traffic types, such as  
TCP/UDP/ICMP. TCP/UDP/ICMP traffic is forwarded to discarded based on the  
conditions specified in the rule, including source and/or destination address and source  
and/or destination port number. You can have up to 33 rules per filter. Each rule reduces  
the packet throughput of the DSL card.  
There can be 24 filters per DSL card with a maximum of two filters per DSL port, one  
inbound filter and one outbound filter. The same filter can be applied as an inbound filter  
and an outbound filter. Filters are configured on the port card and the processing takes  
place on the endpoint.  
NOTE: Once your rules have been configured, you can then bind and activate the filter  
on the DSL interface using the Configuration → Interfaces → General screen (A-C-A).

Item – Enter a value from 1–8 to add, delete, or modify individual filter entries.  
Filter Name – Name of the Ethertype filter. (This field is read-only.)  
Rules – Number of rules in the Ethertype filter (0–33). (This field is read-only.)  
Def. Filter Action – Forward/Discard. Default filter action. (This field is read-only.)  
Interface – DSL interface to which the filter belongs (for example, dsl1:1 through dsl12:1  
for 12-port cards). (This field is read-only.)  
Filter Status – Active/Inactive. (Default = Inactive). (This field is read-only.)  
Direction – Inbound/Outbound. (This field is read-only.)  
On the bottom of this screen at the  
Item Number (0 to Add, Item# to Edit, -Item# to Delete)prompt:  
Select 0 (zero) to add a new filter.  
Select # (n) to edit existing filters. Example: Enter 3 to add Filter #3.  
Select –# (–n) to delete a filter. Example: Enter –6 to delete Filter #6.  
The Add or Edit selection takes you to the Ethertype FIlter Configuration screen. When  
you exit that screen, you return to the Ethertype Filter screen.  
NOTE: Deleting the filter deletes all the rules associated with that filter.  
Ethertype Filter (Ethertype Filter Configuration screen)  
(A-G-B)  
Allows you to build multiple rules for an Ethertype filter. A filter consists of a set of rules  
applied to a specific interface to indicate whether a packet received or sent out of that  
interface is forwarded or discarded. You can add, edit, or delete filter rules within a named  
set.  
A filter works by successively applying the rules to the information obtained from the  
packet header until a match is found. The filter then performs the action specified by the  
rule on that packet, which forwards or discards the packet. If all the rules are searched  
and no match is found, the configured default filter action is executed.  
Rules are applied in the order in which they are configured. You can have up to 16 rules  
per filter. Each rule reduces packet throughput of the DSL card.  
There can be 24 filters per DSL card with a maximum of two filters per DSL port, one  
inbound filter and one outbound filter. The same filter can be applied as an inbound filter  
and an outbound filter. Filters are configured on the port card and the processing takes  
place on the endpoint.  
NOTE: Once your rules have been configured, you can then bind and activate the filter  
on the DSL interface using the Configuration → Interfaces → General screen (A-C-A).

Overview  
The Hotwire DSL menu lets you monitor the activity of the Hotwire DSL cards.  
When you select Monitoring from the Hotwire DSL Main Menu, a menu tree of  
selections on history and error logs, performance statistics, card status, and  
physical and logical interface status information is presented.  
Most of the Monitoring screens are read-only; that is, the screens displayed are  
designed to help you gather pertinent information and isolate potential problem  
areas. For diagnostic tools and hardware and software troubleshooting  
techniques, see Chapter 5, Diagnostics and Troubleshooting. For more information  
concerning the fields displayed, refer to Chapter 3, DSL Card Configuration.

Procedure  
To view selftest, card alarm, packet test, Service Node selftest, and BERT test  
information:  
1. From the Hotwire – DSL Menu, select:  
Diagnostics (D)  
2. The Diagnostics menu appears. Select the submenu option as shown in  
Table 5-1, Diagnostics Options, and press Enter.  
Table 5-1. Diagnostics Options (1 of 2)  
Selftest  
D-A  
Displays the results of the last disruptive selftest of the DSL card. This selftest is only  
performed on power up of the system or a reset of the card. Each subsystem (processors,  
memory, and interfaces) reports pass or fail. If all subsystems pass, the card has passed  
selftest. If a subsystem fails, reset or replace the card.  
You can determine when the selftest occurred by reading the elapsed time since the last  
reset on the card.  
Alarms (Card Alarms)  
D-B  
Displays all active card alarm conditions.  
Major alarms include Selftest Failure, Sanity Timer, Non-Supported Chassis, DSL or  
Ethernet Port Failures, and Loss of Network Timing (for ports designated as NT). Refer to  
Table 5-2, Major Alarms.  
Minor alarms include Config Error (configuration has been corrupted), Threshold  
Exceeded for DSL Margin or Link Down events, and Wrong SN Ports. Refer to  
Table 5-3, Minor Alarms.  
DSL Packet Echo Test  
D-C  
Allows you to conduct a nondisruptive packet test between the DSL card and Hotwire SN  
endpoint. Test packets are sent to the SN at 10 percent of the line rate and echoed back  
to this card, where they are counted and checked for errors. The running time of the test  
can be specified and the test will continue until the specified time has elapsed or the test  
is stopped. Only one port can be tested at a time.  
Results include packets sent, valid packets received, errored packets received, errored  
seconds, and elapsed time of the test.  
NOTE: Errored packets and errored seconds may result if one SN has heavy Ethernet  
traffic, or two or more SNs have moderate to heavy Ethernet traffic (such as in a  
multidrop environment).  
SN Selftest  
D-D  
Allows you to perform a power-on Service Node selftest. A port number can be selected  
to perform the test.  
NOTE: Entering yes in the Reset SN field will temporarily disrupt the data path on the  
specified DSL port while the SN resets.

Interface Name – Enter port number:interface number. The interface number (1–4)  
represents each of the possible Service Nodes that may be attached to the selected port.  
The link to the Service Node must be active to run the BERT since packets are  
exchanged between the Access Node and the Service Node.  
Serial Number – The serial number of the Service Node appears in this field when you  
enter an Interface Name.  
Duration – (1–65535). Enter the number of packets that will be exchanged in both the  
upstream (Service Node to Access Node) and downstream (Access Node to Service  
Node) directions. If you enter a number from 1 through 65534, this is an iterative test. If  
you enter 65535, this is a continuous test.  
Test Type – Displays one of the following:  
Iterative – You entered a number from 1 through 65534 in the Duration field. The  
test stops after the transfer of the specified number of packets.  
Continuous – You entered 65535 in the Duration field. The test runs until you select  
Stop Test.  
Start Test – Type y to start the test. You may display the results of the test just started, or  
you may start a BERT on another interface by typing Ctrl-z, then reentering this screen  
and selecting another interface to test.  
Stop Test – Type y to stop the test.  
Test Status – Displays Test Starting (Access Node is communicating the test request to  
the Service Node), Test Running (Access Node and Service Node are exchanging test  
packets), or Test Complete.  
Next TX Sequence Number – The number of the next test packet to be sent from the  
Access Node to the Service Node. Begins with the number entered in the Duration field  
and counts down to 0.  
Next RX Sequence Number – The number of the next test packet expected to be  
received by the Access Node from the Service Node. Begins with the number entered in  
the Duration field and counts down to 0.  
Results – Displays the following:  
Number of Good/Bad Blocks Received for Upstream and Downstream – Only  
updated in downstream direction for an Iterative test. The upstream direction is  
updated for an Iterative test once the test has completed. Both upstream and  
downstream directions are updated during an Continuous test.

Troubleshooting  
The status of each card in the Hotwire chassis is indicated on the Card Selection  
screen (see Components of a Hotwire Screen in Chapter 2, Hotwire Menus and  
Screens).  
Checking Alarms  
If the Card Selection screen indicates that a Major or Minor Alarm is on a card,  
follow the menu selection sequence Diagnostics → Alarms (D-B) to determine the  
cause of the alarm.  
No Response at Startup  
DSL cards do not respond at startup after rebooting chassis. Reset the MCC card.  
Be sure LEDs go through the reset sequence twice within about one minute.  
If a DSL card does not appear on the Card Selection screen because the MCC  
card can no longer communicate with it, the MCC card will generate a major  
alarm. Follow the MCC’s menu selection sequence Monitor → Card → Syslog  
(B-A-C) and view the event on the MCC Card System Log.  
Major Alarms  
Use Table 5-2, Major Alarms, to determine the appropriate action to take for each  
Major Alarm.  
Table 5-2. Major Alarms (1 of 3)  
Alarm  
Action  
Selftest Failure 1. Check the Selftest Results display by following the menu selection  
sequence: Diagnostics → Selftest (D-A)  
2. Do another Selftest (Reset) and check results.  
– If the results are normal, the problem was transient. Log the  
results.  
– If the results are the same as the first selftest, the card should be  
replaced. If only one port on a DSL card is bad, that port can be  
disabled. You may continue to use the card until it is convenient  
to replace it.  
Processor  
Failure (Sanity  
Timer)  
1. Check the Selftest Results display by following the menu selection  
sequence: Diagnostics → Selftest (D-A)  
2. Do another Selftest (Reset) and check results.  
– If the results are normal, the problem was transient. Log the  
results.  
– If the results are the same as the first selftest, the card should be  
replaced.  
Non-Supported Check that the chassis supports the card (e.g., only 8610, 8810 and  
Chassis  
8820 support the 8312 card).

Table 5-2. Major Alarms (2 of 3)  
Alarm  
Action  
Ethernet Port  
Failure  
1. Check cable connections to the chassis.  
– If cables are terminated properly, go to Step 2.  
– If cables are not terminated properly, terminate them correctly.  
2. Check cable connections to the hub or Ethernet switch.  
– If cables are terminated properly, go to Step 3.  
– If cables are not terminated properly, terminate them correctly.  
3. Check the Activity/Status LED at the Ethernet hub.  
– If Activity/Status LED does not indicate a problem, go to Step 4.  
– If Activity/Status LED indicates a problem, take appropriate  
action.  
4. Disconnect the Ethernet cable and replace it with a working cable  
from a spare port on the hub.  
– If the replacement cable works, the original is bad and should be  
permanently replaced.  
– If the replacement cable does not work, reconnect the original  
cable and go to Step 5.  
5. Move the DSL card and cable to another (spare) slot.  
– If this solves the problem, the connector or interface panel  
connections for the original slot are bad. Schedule maintenance  
for the chassis and try to use the spare slot temporarily.  
– If this does not solve the problem, the DSL card is probably bad  
and should be replaced.  
Link Down  
Threshold  
If the threshold is set low (1–4) and the link is currently down, then  
there may be a local loop or Service Node problem. Check both.

If the threshold is set high (more than 4) and the link is currently  
down, then check the Margin statistics over the past hour and day. If  
the numbers are low, there may be a situation where the DSL  
modems cannot train. This condition may be temporary or  
permanent. However, if it persists, the loop may have to be  
reengineered for better performance by performing one of the  
following:  
– Remove bridge taps.  
– Change cable gauge on a cable section.  
– Run new cable.  
– Remove other noise-generating digital circuits from the cable  
bundle.  
If the threshold is set high (more than 4) and the link is currently up,  
then there may be a loose connection in the loop plant, or the loop  
is barely usable. Check the Margin. If the Margin is normal, there  
may be a loose connection. If the Margin is low, try reducing the  
speed of the DSL port.

02/18/2000 09:53:50 Remote Started at 02/18/2000 09:53:28  
02/18/2000 09:53:50 Remote Reed Solomon Restart, Port 4  
Meaning:  
The port S/N ratio has been reached. The port card retrained after the remote unit  
as indicated by the embedded timestamp at the end of the remote SYSLOG  
message. This retrain was caused by Reed Solomon errors. In general, if the port  
card is experiencing a line performance problem and enters the retrain state first,  
the remote unit typically retrains due to Reed Solomon Restart. If the remote unit  
enters the retrain state first, the port card will typically show a S/N Threshold  
Reached error message.  
Example 3. System Status Message  
The following SYSLOG message have been received:  
02/18/2000 11:13:15 Link Transition Threshold Exceeded, port DSL2  
Meaning:  
The number of DSL retrains (transitions) has exceeded the Link Down Count  
configured on the DSL Parameters screen (A-B-B). This is checked every  
15 minutes when the current 15-minute bucket is shifted to the previous 15-minute  
bucket. There will never be more than one SYSLOG message for each 15-minute  
period. The Link Down Count only determines if a trap is sent. It has no effect on  
when the units will retrain.

5. Diagnostics and Troubleshooting  
High-Level Troubleshooting  
The following high-level procedures help you isolate problems to a particular  
segment of the network.  
For static clients, make sure the client can Ping its own IP address. This  
confirms the IP address was successfully accepted by the client computer.  
Make sure the client’s default gateway is the same as the IP address for the  
Bridge Virtual Interface (BVI) on the appropriate ISP router.  
An Address Resolution Protocol (ARP) table may have invalid entries if a  
recent configuration change took place anywhere on the network and not  
enough time has passed for the entry to expire. Check the ARP tables on the  
client, AN, and router.  
Make sure a default route is configured on the MCC card (screen A-E-A).  
The following table provides an overview of the sequence of troubleshooting  
procedures for the DSL card. The following sections address potential problems  
that may occur in each network segment:  
If the Client cannot Ping the  
Gateway Router and . . .  
Then . . .  
The Client cannot reach the SN  
Refer to Table 5-4, Client-to-Service Node

5. Diagnostics and Troubleshooting  
Client Cannot Reach Service Node  
Table 5-4. Client-to-Service Node Segment  
Layer  
Solution  
Layer 1 –  
Physical  
1. Make sure the PWR LED on the front of the Service Node is lit. Use only  
the power adapter shipped with the unit.  
2. To verify connection to the client, make sure the ETHERNET LED on the  
front of the Service Node is lit.  
3. Make sure there is a physical connection between the Service Node and  
the Network Interface Card (NIC). If there is a LINK LED on the NIC card,  
make sure it is lit.  
4. If there is a hub, check its cables and LEDs.  
5. Make sure the correct type of cable is being used between the client and  
the Service Node. A crossover cable should be used if the client is not  
connected to a LAN hub.  
6. Make sure the NIC and drivers are correctly installed.  
7. Make sure the correct Service Node firmware is being used.  
Layer 2 –  
Network  
1. If static addressing is used, make sure the client has its correct IP  
address and subnet mask by entering the following:  
– Windows 95: winipcfg  
– Windows NT: ipconfig/all  
For other operating systems, use help or see the appropriate manual.  
2. Restart the client after a static IP address has been added or changed.  
3. Make sure the client can Ping its own IP address. This confirms the IP  
address was successfully accepted by the computer.  
4. Check the PC’s default gateway to make sure it is functioning properly.  
1. If dynamic addressing is being used and the client cannot get an IP  
address from the Dynamic Host Configuration Protocol (DHCP) server,  
statically configure an IP address and then verify that the client can Ping  
the DHCP server.  
2. After the client reaches the server, remove the IP address and return the  
system to dynamic (DHCP) addressing.  
Make sure there are 32 or fewer DHCP users active on the port at any given  
time. Only 32 users are entered into the host table.  
If the problem persists after the above items are checked, the client-to-service  
node segment of the network is functional.

5. Diagnostics and Troubleshooting  
Client Cannot Reach DSL Card(s)  
This section examines the Service Node-to-DSL card segment of the network.  
NOTE:  
On the DSL card, verify that the DSL link is up and that there is a MAC  
address for the client (screen B-E-B).  
— If the MAC address appears, and all items in the previous section have  
been examined, it is safe to assume that this network segment is  
functioning. Skip this section and go to Table 5-6, AN-to-IPC Segment.  
— If a MAC address does not appear, check the items in

5. Diagnostics and Troubleshooting  
Table 5-5. Service Node-to-DSL Card (Access Node) Segment (2 of 2)  
Layer  
Solution  
Layer 1 –  
Physical  
1. Make sure the LINE LED on the SN is lit. This verifies a DSL  
connection to the AN.  
(continued)  
2. On the AN, make sure the LINE STATUS is up.  
3. Make sure the CO splitter is connected correctly. The DSL line goes to  
the 50-pin amphenol jack on the chassis and the other line goes to the  
PSTN switch in the central office.  
4. Make sure the 50-pin amphenol jack is firmly attached to the correct  
interface on the chassis. For the 20-slot chassis, the ports are labeled  
1-6, 7-12, and 13-18.  
5. Make sure the loop characteristics are within MVL/RADSL/SDSL  
specifications.  
Layer 2 –  
1. On the AN, if using static IP addressing, make sure the address is  
Network  
correctly configured (screen A-E-F).  
2. On the AN, make sure all configured ports are in use (screen B-B-A).  
If ports are not in use, properly configure them.  
3. On the AN, check the status of the port (screen A-C-B). If the status is  
not active, restart the port.  
4. If dynamic addressing is being used and the clients cannot get an  
IP address from the DHCP server, statically configure an IP address  
and then verify that the client can Ping the DHCP server. After the  
client reaches the server, remove the IP address and return the  
system to dynamic (DHCP) addressing.  
5. An ARP table may have invalid entries if a recent configuration change  
took place anywhere on the network and enough time has not passed  
for the entry to expire. Check the ARP tables on the client, AN, and  
router.  
6. To ensure connection between the AN and SN, perform a packet echo  
test (screen D-C). Make sure the number of packets sent is the same  
as the number of packets received. If fewer packets are being received  
than sent, the SN may not be functioning correctly.  
7. If the AN fails to connect to the SN, attempt to connect upstream and  
downstream at lower speeds or configure the card to rate adaptive  
mode (screen A-B-B). When a speed is changed, the port must be  
restarted (screen A-C-B) for the change to take effect.  
If the problem persists after the above items are checked, the client-to-DSL card  
segment of the network is functional.

Client Cannot Reach IPC  
This section examines the AN-to-IPC segment of the network.  
NOTE:  
On the IPC, verify that there is a MAC address for the client (enter the  
macinfo command). If the correct MAC address appears on the IPC, and all  
the items in the previous sections have been examined, it is safe to assume  
that this segment of the network is functioning properly. Skip this section and  
go to Client Cannot Reach Router on page 5-19. If a MAC address does not  
appear, check the items in Table 5-6, AN-to-IPC Segment.

If the DSL card shows an alarm, go to screen D-B to determine the cause.  
An Ethernet alarm usually means no connection to the IPC. Check the cable  
and make sure the correct type is being used.  
On AN, make sure the Ethernet cable is plugged into the port number that  
corresponds to the slot number of the card.  
Layer 2 –  
If applicable, verify that the desired mode (tagged or untagged) is selected  
Network  
(screen A-E-A). Reset the card if a change is made.  
If VNID tagging is enabled on the AN (screen A-E-A):  
1. Make sure a card VNID is configured (Card VNID Table, screen A-E-B).  
For each connection, the VNID number must be the same as the group  
number on the IPC.  
2. Make sure a card VNID is entered (screen A-E-B). If VNID tagging is  
disabled, Card VNIDshould be set to none.  
3. Make sure the appropriate VNID is active on the correct port (screen  
A-E-C). An asterisk (*) indicates the active VNID. If VNID tagging is  
disabled, noneshould be active on each port.  
4. Make sure the IPC Ethernet port is part of a 802.1Q (VNID) group. To  
view VNID groups, enter viqgp.  
On the IPC:  
NOTE: With firmware earlier than 3.2.3, follow Steps 1 through 3.  
For firmware later than 3.2.3, skip Step 1.  
1. For VLAN functionality, the mpm.cmd file must contain these lines:  
group_mobility=1  
move_from_def=1  
If necessary, add the lines and reboot the IPC.  
2. Make sure that all modules are supported by their respective image  
(.img) files. Enter ls to view file names. If a customer data upgrade is  
already done on the mpm.cmd file, you have two directories:  
/ and /sim.  
3. Enter gp to make sure the group is configured correctly.

1. On the IPC, make sure the cables are firmly attached to the WAN  
interface.  
2. If no CSU/DSUs are being used, either the router or the IPC must provide  
network clocking. Network clocking is usually provided by the device  
connected to the DCE cables.  
3. If no CDU/DSUs exist between IPC and Router, make sure transmission  
lines are active by looking for appropriate LEDs.  
4. If there is no connection between the router and IPC, invert the clocking  
on one or both DSU/CSUs.

On the IPC:  
Network  
1. Set payload scramble to false. To turn PLScramble on or off on the IPC,  
type map slot/port (where slot/port is that of the ATM card) and set 10=1  
to false.  
2. If using SONET, make sure that the line characteristics are correct. Type  
map slot/port and select the Phy Media option.  
3. Enter vas to make sure a service is configured.  
4. Make sure encapsulation is the same as on the router (RFC1483).  
5. Enter vvc to make sure vpi and vci are configured correctly.  
6. Enter vcs to view ATM connection statistics.  
7. Enter vcrs and vcts to view transmitted and received cells.

1. On the router, make sure that the defined line characteristics agree with  
the characteristics defined on the IPC.  
2. Make sure a virtual circuit is configured under the respective ATM  
subinterface. The PVC number should correspond to the PVC number on  
the IPC.  
3. Make sure a bridge-group number is configured under the respective  
ATM subinterface and that the BVI number is the same as the  
bridge-group number.  
4. Make sure encapsulation on the router is the same as on the IPC  
(RFC1483).  
5. Make sure the client’s default gateway is the same as the IP address for  
BVI on the appropriate ISP router.  
6. If a Ping from the client is not successful, issue a show ARP-cache  
command on the router to make sure the correct MAC address and client  
IP address appear.

Performance Issues – Viewing Network Statistics  
The previous sections of this document examined connectivity issues, i.e., the  
inability to Ping the router. Table 5-9, Examining Performance Issues, presents  
information on viewing DSL card statistics screens to examine performance  
issues.  
These statistic screens give information related to the number of packets  
transmitted and received on an interface as well as any packet failures. Refer to  
Physical Layer Menu Options in the Hotwire Management Communications  
Controller (MCC) Card, IP Conservative, User’s Guide for details on the Statistics  
screens.

Performance  
Screen B-B-B. Slow performance could result from errors seen on  
this screen.  
Make sure the DSLAM and IPC are both operating at either full- or  
half-duplex mode. On the AN, go to screen A-B-A. On the IPC, enter  
10/100cfg. If operating at full-duplex, a hub should not be used.  
Check the Ethernet Statistics screen for excessive Cycle  
Redundancy Check (CRC) errors, a bad connection, or a bad cable  
(see DSL Monitoring Physical Layer Screens in Chapter 4,  
Monitoring the Hotwire DSL System).  
Examine  
Collisions  
Screen B-B-B. Minimal collisions are acceptable if packets are not  
being discarded. Excessive collisions could result from forcing too  
much data over a single Ethernet.  
1. Determine if your network is too large or long (single Ethernet  
cable or end-to-end cable).  
2. Check to see if there are too many repeaters.  
3. Check to see if there are too many users on a single Ethernet.  
Intranetworking communication problems:  
1. Verify that the internetworking network cables meet IEEE  
standards for local Ethernet networks.  
2. Check cable connections to chassis and other devices in the  
network.  
3. Determine whether or not your system is the only one in the  
network with a problem.

Download Code Menu Option  
The Download Code menu option (A-F) allows you to upgrade your software with a  
new version of code, then apply this code to your system.  
New firmware releases are typically applied to the MCC card, DSL cards, and/or  
endpoints in your system.  
When a software upgrade affects both the MCC and all DSL cards, you must  
download and apply a new version of code into each of the DSL cards before you  
download and apply a new version of code into the MCC. However if you are  
upgrading from MVL to ReachDSL, you must ensure that the MCC card is at a  
minimum revision level of 04.01.16 before you upgrade the MVL card to  
ReachDSL.  
When you are downloading code to an endpoint, configure your TFTP server with  
the following timeout values:  
Retransmission timeout – Value not less than 10 seconds.  
Total transmission – Value not less than three times the retransmission  
timeout.  
You can also use the above values for a standard TFTP transfer.
