Handling Energized Products  
General Safety Practices  
Do not touch or tamper with the power supply when the power cord is connected. Line voltages may be  
present inside certain products even when the power switch (if installed) is in the OFF position or a fuse is  
blown. For DC-powered products, although the voltages levels are usually not hazardous, energy hazards  
may still exist.  
Before working on equipment connected to power lines or telecommunication lines, remove jewelry or any  
other metallic object that may come into contact with energized parts.  
Unless otherwise specified, all products are intended to be grounded during normal use. Grounding is  
provided by connecting the mains plug to a wall socket with a protective earth terminal. If an earth lug is  
provided on the product, it should be connected to the protective earth at all times, by a wire with a  
diameter of 18 AWG or wider. Rack-mounted equipment should be mounted only in earthed racks and  
cabinets.  
Always make the ground connection first and disconnect it last. Do not connect telecommunication cables  
to ungrounded equipment. Make sure that all other cables are disconnected before disconnecting the  
ground.  
Connection of AC Mains  
Make sure that the electrical installation complies with local codes.  
Always connect the AC plug to a wall socket with a protective ground.  
The maximum permissible current capability of the branch distribution circuit that supplies power to the  
product is 16A. The circuit breaker in the building installation should have high breaking capacity and must  
operate at short-circuit current exceeding 35A.  
Always connect the power cord first to the equipment and then to the wall socket. If a power switch is  
provided in the equipment, set it to the OFF position. If the power cord cannot be readily disconnected in  
case of emergency, make sure that a readily accessible circuit breaker or emergency switch is installed in the  
building installation.  
In cases when the power distribution system is IT type, the switch must disconnect both poles  
simultaneously.  
Connection of DC Mains  
Unless otherwise specified in the manual, the DC input to the equipment is floating in reference to the ground.  
Any single pole can be externally grounded.  
Due to the high current capability of DC mains systems, care should be taken when connecting the DC supply  
to avoid short-circuits and fire hazards.  
DC units should be installed in a restricted access area, i.e. an area where access is authorized only to  
qualified service and maintenance personnel.  
Make sure that the DC supply is electrically isolated from any AC source and that the installation complies  
with the local codes.  
The maximum permissible current capability of the branch distribution circuit that supplies power to the  
product is 16A. The circuit breaker in the building installation should have high breaking capacity and must  
operate at short-circuit current exceeding 35A.  
Before connecting the DC supply wires, ensure that power is removed from the DC circuit. Locate the  
circuit breaker of the panel board that services the equipment and switch it to the OFF position. When  
connecting the DC supply wires, first connect the ground wire to the corresponding terminal, then the  
positive pole and last the negative pole. Switch the circuit breaker back to the ON position.  
A readily accessible disconnect device that is suitably rated and approved should be incorporated in the  
building installation.  
If the DC mains are floating, the switch must disconnect both poles simultaneously.

Connection of Data and Telecommunications Cables  
Data and telecommunication interfaces are classified according to their safety status.  
The following table lists the status of several standard interfaces. If the status of a given port differs from  
the standard one, a notice will be given in the manual.  
Ports  
Safety Status  
V.11, V.28, V.35, V.36, RS-530,  
X.21, 10 BaseT, 100 BaseT,  
Unbalanced E1, E2, E3, STM, DS-2,  
DS-3, S-Interface ISDN, Analog voice  
E&M  
SELV Safety Extra Low Voltage:  
Ports which do not present a safety hazard. Usually  
up to 30 VAC or 60 VDC.  
xDSL (without feeding voltage),  
Balanced E1, T1, Sub E1/T1  
TNV-1 Telecommunication Network Voltage-1:  
Ports whose normal operating voltage is within the  
limits of SELV, on which overvoltages from  
telecommunications networks are possible.  
FXS (Foreign Exchange Subscriber)  
TNV-2 Telecommunication Network Voltage-2:  
Ports whose normal operating voltage exceeds the  
limits of SELV (usually up to 120 VDC or telephone  
ringing voltages), on which overvoltages from  
telecommunication networks are not possible. These  
ports are not permitted to be directly connected to  
external telephone and data lines.  
FXO (Foreign Exchange Office), xDSL TNV-3 Telecommunication Network Voltage-3:  
(with feeding voltage), U-Interface  
Ports whose normal operating voltage exceeds the  
ISDN  
limits of SELV (usually up to 120 VDC or telephone  
ringing voltages), on which overvoltages from  
telecommunication networks are possible.  
Always connect a given port to a port of the same safety status. If in doubt, seek the assistance of a  
qualified safety engineer.  
Always make sure that the equipment is grounded before connecting telecommunication cables. Do  
not disconnect the ground connection before disconnecting all telecommunications cables.  
Some SELV and non-SELV circuits use the same connectors. Use caution when connecting cables.  
Extra caution should be exercised during thunderstorms.  
When using shielded or coaxial cables, verify that there is a good ground connection at both ends. The  
earthing and bonding of the ground connections should comply with the local codes.  
The telecommunication wiring in the building may be damaged or present a fire hazard in case of  
contact between exposed external wires and the AC power lines. In order to reduce the risk, there are  
restrictions on the diameter of wires in the telecom cables, between the equipment and the mating  
connectors.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Caution  
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cords.  
Attention  
Pour réduire les risques s’incendie, utiliser seulement des conducteurs de  
télécommunications 26 AWG ou de section supérieure.  
Some ports are suitable for connection to intra-building or non-exposed wiring or cabling only. In such  
cases, a notice will be given in the installation instructions.  
Do not attempt to tamper with any carrier-provided equipment or connection hardware.  
Electromagnetic Compatibility (EMC)  
The equipment is designed and approved to comply with the electromagnetic regulations of major  
regulatory bodies. The following instructions may enhance the performance of the equipment and will  
provide better protection against excessive emission and better immunity against disturbances.  
A good earth connection is essential. When installing the equipment in a rack, make sure to remove all  
traces of paint from the mounting points. Use suitable lock-washers and torque. If an external  
grounding lug is provided, connect it to the earth bus using braided wire as short as possible.  
The equipment is designed to comply with EMC requirements when connecting it with unshielded  
twisted pair (UTP) cables. However, the use of shielded wires is always recommended, especially for  
high-rate data. In some cases, when unshielded wires are used, ferrite cores should be installed on  
certain cables. In such cases, special instructions are provided in the manual.  
Disconnect all wires which are not in permanent use, such as cables used for one-time configuration.  
The compliance of the equipment with the regulations for conducted emission on the data lines is  
dependent on the cable quality. The emission is tested for UTP with 80 dB longitudinal conversion loss  
(LCL).  
Unless otherwise specified or described in the manual, TNV-1 and TNV-3 ports provide secondary  
protection against surges on the data lines. Primary protectors should be provided in the building  
installation.  
The equipment is designed to provide adequate protection against electro-static discharge (ESD).  
However, it is good working practice to use caution when connecting cables terminated with plastic  
connectors (without a grounded metal hood, such as flat cables) to sensitive data lines. Before  
connecting such cables, discharge yourself by touching earth ground or wear an ESD preventive wrist  
strap.

Multiplexer Applications  
Notes  
Note  
• The multiplexer unit cannot be configured as a device with LAN only port. It  
must have a DTE or IR port.  
• The hardware of a single unit-based product with a LAN port manager is  
different from that of a multiplexer-based product.  
The hardware has different options for the modem to work as a multiplexer.  
Table 1-4 shows all the available multiplexer combinations that can be used.  
Software for a multiplexer version is available but is not transferable to a single port  
unit.

Remote management via out-of-band 10/100BaseT port or dedicated timeslot.  
Remote management is performed using Telnet, or ConfiguRAD (RAD’s  
Web-based application), or RADview (RAD’s SNMP-based management  
system).  
Managing ASMi-52 via a Terminal Port  
This section describes how to prepare ASMi-52 and the supervisory terminal for a  
control session.  
Control Port Interface Characteristics  
ASMi-52 includes a V.24 (RS-232) asynchronous DCE port, designated as  
CONTROL and terminating in a 9-pin D-type female connector. The control port  
continuously monitors the incoming data stream and immediately responds to any  
input string received through this port.  
The terminal can be connected either directly to the ASMi-52 control port, or  
through a modem or any other type of full-duplex data link. The ASMi-52 control  
port interface type must be set in accordance with the connection method, as  
follows:  
•
DCE – direct connection to terminals. Since terminals usually have DTE  
interfaces, the connection to the port is made by means of a cable.  
•
DTE – connection through a modem or data link. In this case, you need a  
cross-cable (also called a null modem cable) to connect to the CONTROL  
connector.  
The ASMi-52 control port can be configured to communicate at the following  
rates: 9.6, 19.2, 38.4, 57.6, or 115.2 kbps.  
The word format consists of one stop bit, 8 data bits, and no parity.  
Note  
ASMi-52 can also be managed via a hand-held control device, Easy Config. Refer to  
Appendix C for detailed description of the device.  
Preparing the Terminal  
Any standard ASCII terminal (a “dumb” terminal or a personal computer running  
a terminal emulation application) equipped with a V.24 (RS-232) communication  
interface can be used to configure ASMi-52. Appendix A details the pin  
assignments and control signal directions of the ASMi-52 control connector.  
Data Terminal Ready (DTR)  
When connected and turned on, the terminal sets the DTR line ON (active) to gain  
control over ASMi-52 and starts a configuration or monitoring session.  
Initiating a Control Session  
ꢀ
To initiate a control session:  
1. Connect the terminal cable to the CONTROL connector of ASMi-52.  
2. Turn the control terminal on.

3. Configure the terminal to the default communication parameters: 9.6 kbps,  
one start bit, eight data bits, no parity, one stop bit, VT100 emulation.  
4. Select the full duplex mode.  
5. Turn the terminal echo off.  
6. Disable any type of flow control.  
You are now ready to start a control session.

Configuring Dedicated Timeslots  
ASMi-52 units with an E1 or T1 port support management via a dedicated  
timeslot.  
A remote E1 device can be managed via DTS if the DTS mode is enabled in both  
the CO unit and the CPE unit. The MNG timeslot is transferred over the SHDSL to  
the E1 CPE, the CPE forwards the MNG timeslot over the E1 line to the next  
device in the chain.  
•
Note  
Allocate the same timeslot number for MNG in all devices in the chain. With DTS  
mode enabled in all devices, the chain can be managed remotely from one NMS.  
In T1 systems, the DTS manages the local unit only; it is not forwarded over SHDSL.  
ꢀ
To configure dedicated timeslots:  
1. From the DTS Configuration menu (Main menu > Configuration > System  
Configuration > Management > DTS Configuration), configure the dedicated  
timeslot in the following order (see Figure 4-7):  
ꢀ Assign a DTS IP address  
ꢀ Assign a DTS IP mask  
ꢀ Enable the DTS mode.  
2. Check the status of the DTS configuration in the Rem Agent Table (see Figure 4-8).

Configuring VLAN Encapsulation  
ASMi-52 is occasionally connected to a VLAN network when management VLAN  
messages are required. Virtual LANs enable network managers to group users  
logically rather than by physical location. A virtual LAN (VLAN) is an emulation of a  
standard LAN that allows data transfer and communication to occur without the  
traditional restraints placed on the network.  
The VLAN encapsulation feature enables or disables a user to work in VLAN  
mode, identify the user to give the user the proper VLAN permissions and to  
prioritize a VLAN session.  
ꢀ
To enable VLAN mode:  
1. From the Management menu (Main menu > Configuration > System  
Configuration > Management > VLAN Encapsulation), select VLAN  
Encapsulation (see Figure 4-9).  
The VLAN Encapsulation is displayed.  
2. From the VLAN Encapsulation menu, select VLAN mode.  
3. Enable the VLAN mode feature.  
4. Select VLAN Management ID to identify the user.  
The identification will grant the user VLAN support.  
5. Select the VLAN Priority option if you wish to prioritize the session.

Configuring the LAN Port  
ASMi-52 includes a 10/100BaseT port that can be used as a user or management  
port. The LAN port operates in a self-learning bridge or transparent mode, with or  
without autonegotiation.  
Note  
If the LAN port serves as a management port only, it operates in transparent mode  
with autonegotiation enabled.  
Configuring the LAN Port Operation Mode  
In the transparent mode, the LAN port operates with a disabled filter, passing all  
frames transparently. When operating as a self-learning bridge, the LAN port filters  
the packets received from the local LAN and transfers through the link only frames  
destined for another LAN.  
ꢀ
To configure the LAN operation mode:  
1. From the Operation Mode menu, select the Bridging Mode option (Main  
menu > Configuration > LAN Configuration > Local LAN Configuration >  
Bridging Mode) to enable bridge mode.

Setting the LAN Rate in a Multiplexer Unit  
The maximum multiplexer rate is 2048 kbps (general rate). The sum of the data  
rate of two interfaces should not exceed 2048 kbps.  
For example:  
•
IR (DTE Serial) Interface + LAN – If IR or the DTE Serial Interface works at  
1024 kbps, then LAN cannot work at a speed of more than 1024 kbps  
because the sum of both interfaces cannot exceed 2048 kbps.  
ASMi-52 has a multiplexer modem with two interfaces. The maximum rate for  
LAN is:  
•
If LAN + E1, then the LAN maximum rate =  
2048 kbps – used TSs (timeslots) x 64 kbps  
•
If LAN + IR (DTE Serial) Interface, then the LAN maximum rate =  
2048 kbps – DTE rate  
Configuring Autonegotiation  
ASMi-52 autonegotiation allows you to operate at the fastest data rate available.  
With autonegotiation enabled, the ASMi-52 unit automatically determines  
between itself and the DTE the fastest data rate and duplex mode that they can  
operate. With autonegotiation disabled, the LAN interface of ASMi-52 operates at  
the speed and duplex mode that is configured by the Default type.  
ꢀ
To set autonegotiation:  
1. From the Local LAN Configuration menu, select Autonegotiation (Main menu

command that is sent to the dial-out modem. When connecting the dial-out  
modem, you must use a cross cable (see Appendix A for the cross cable pinout).  
The modem connected to the CONTROL connector must be set up as follows (for  
convenience, the Hayes commands required to select the specified parameters are  
listed in brackets):  
•
•
•
•
Auto-answer mode (AT S0=1 and AT S1=1)  
Call set up in response to the CONNECTstring (AT X0)

Configuration > System Configuration > Control Port > Port Control > Port  
Control Mode > Dial Out).  
The Dial Out menu appears (see Figure 4-26).  
2. From the Dial Out menu, type the following:  
ꢀ 1 to instruct ASMi-52 to report all alarms (ALL), only major ones (MAJOR),  
or disable alarm reporting (NONE).  
ꢀ 2 to specify the number of dialing retries. 0, no redialing attempts are made  
if the call is not established on the first attempt. 1–8, if the call is not  
established on the first attempt, ASMi-52 makes the specified number of  
redials.  
This parameter applies to both primary and alternate numbers:  
ꢁ
If the call is not established after dialing the primary directory number  
the specified number of times, ASMi-52 attempts to establish the call by  
dialing the alternate directory number (provided the use of an alternate  
number is enabled).  
ꢁ
If the call is not established within the specified number of redialing  
attempts on neither of the two directory numbers, ASMi-52 stops the  
call attempts. When a new alarm report must be sent, the call attempts  
are started again. The user is notified that the call attempts failed by a  
message recorded in the alarm log file (separate messages are provided  
for each directory number).

Configuring the Power Spectral Density  
By configuring the power spectral density, you define the amount of power  
applied to the spectrum of frequencies that carry the information signal in order to  
achieve a satisfactory level of signal strength at the receiving end of the circuit.  
The power spectral density can be configured for the ASMi-52 units with the line  
probing set to fixed.  
The power spectral density value depends on the selected modems’ compatibility:  
Annex A or Annex B. The possible values are:  
•
•
Symmetric, supported in both Annex A and Annex B modes.  
Asymmetric, supported in Annex A at 768 kbps and in Annex B at 2048 kbps.  
ꢀ
To configure the power spectral density:  
1. From the SHDSL Local Port menu, select Asym PSD (Main menu >  
Configuration > SHDSL Configuration > SHDSL Local Port > Asym PSD) to  
choose the power spectral density value: symmetrical or asymmetrical.  
The display is refreshed and a new value appears.  
2. Select Save to save the changes.  
Note  
Remote ASMi-52 units automatically detect the line power density. This parameter  
is permanently set to Sym/Asym Enable and cannot be changed.  
Configuring Line Probing  
By configuring this parameter, you force ASMi-52 to perform line probing in order  
to find the best possible rate of transmission – adaptive rate. Or you command the  
modem to skip the rate adaptation phase – fixed rate.  
Only central ASMi-52 units with the 2-wire line interface support fixed and  
adaptive rates, remote units operate with adaptive rate only.  
ASMi-52 units with the 4-wire line interface support only fixed rate.  
ꢀ
To configure line probing:  
1. From the SHDSL Local Port menu, select Line Prob (Main menu >  
Configuration > SHDSL Configuration > SHDSL Local Port > Line Prob).  
The display is refreshed and a new value appears.  
2. Select Save to save the changes.  
Setting the Loop Attenuation Threshold  
Loop attenuation is different (in dB) between the power transmitted from the  
ASMi-52 modem and the power received by the unit operating at the other side of  
the application. By setting the threshold, the modem is instructed to generate  
minor alarm (LOOP ATTN. OVER LINE A/B) when the selected loop attenuation  
threshold value is exceeded.  
ꢀ
To set the loop attenuation threshold:  
1. From the SHDSL Local Port/SHDSL Remote Port/SHDSL Repeater menu,

Configuring the Data Rate in a Multiplexer Unit  
The maximum multiplexer rate is 2048 kbps (general rate). The sum of the data  
rate of two interfaces should not exceed 2048 kbps.  
ASMi-52 is a multiplexer modem with two interfaces that has the following  
maximum rate for Serial DTE interface:  
•
If DTE Serial + E1 interface, then the DTE Serial maximum rate = 2048 kbps  
– used TSs (timeslots) x 64 kbps.  
•
If DTE Serial + LAN interface, then the DTE Serial maximum rate =  
2048 kbps – LAN rate.

Updating Software Releases  
This section presents procedures for installing new software releases into the  
ASMi-52 units, as well as swapping existing software versions in a local or remote  
unit.  
ASMi-52 stores two software versions, each of them in one of the two 512-byte  
partitions of its flash memory, which also contains a boot program. The software is  
stored in compressed format. The active version is decompressed and loaded into  
the ASMi-52 RAM upon power-up. The passive software is kept for backup  
purposes. By default, ASMi-52 is delivered with the active software only.  
New software releases are distributed on diskettes as an *.img file, which is  
downloaded to the local ASMi-52 using the TFTP or XMODEM protocol. Upon  
downloading, the new software release becomes active, the former active software  
turns into backup, and the former backup is erased.  
If a failure occurs during downloading or decompression, the new version is erased  
from the flash and the backup version becomes active. In this case, only one  
version is left stored in the flash memory. If the active software becomes  
corrupted, you can replace it with its backup.  
Installing a New Software Release via TFTP  
ꢀ
To install a new software release via TFTP:  
1. From the SW & File Transfer menu, select TFTP (Figure 4-46) (Main menu >  
File Utilities > SW & File Transfer > SW Download > TFTP).

displaying the following message:  
Final process download. Reset  
After the decompression, ASMi-52 saves the new release as an active  
partition, the former active partition becomes backup. Then the unit resets  
itself. This causes the new software to be loaded into the modem's RAM.  
Installing a New Software Release via XMODEM  
•
Notes  
• Installation of the new software releases via XMODEM is not possible over  
Telnet.  
• To minimize the software downloading time, it is recommended to configure the

5.1 Overview  
This chapter provides detailed instructions for setting up two ASMi-52 modems in  
a typical application.  
ASMi-52 configuration is performed via a menu-driven embedded software using a  
standard ASCII terminal or a PC running a terminal emulation application  
connected to the rear panel CONTROL port. Alternatively, ASMi-52 can be  
managed from a Telnet host connected to the 10/100BaseT port on the rear panel.  
Read Chapter 4 to familiarize yourself with how to operate a terminal.

Displaying E1/T1 Statistics  
When ASMi-52 includes a G.704 E1/T1 port configured to the G732N framing,  
the modem has the capabilities to collect E1/T1 performance diagnostics. Statistics  
collection depends on the use of the CRC-4 function for E1 and T1:  
•
CRC-4 Enabled (E1), ESF framing (T1)  
When the CRC-4 functions are enabled, it is possible to monitor end-to-end  
data transmission performance. Error detection is derived from the data  
payload by performing a cyclic redundancy check (CRC). The resulting CRC  
checksum is transmitted in addition to the raw data bits. The receiving end  
recalculates the checksum and compares the results with the received  
checksum: any difference between the two checksums indicates that one or  
more bits are contained in the current data block being evaluated.  
•
CRC-4 Disabled (E1), SF framing (T1)  
When the CRC-4 option is disabled, ASMi-52 does not support the capabilities  
listed above. However, the modem is capable of providing statistics of bipolar  
violations.

6.2 Detecting Errors  
Power-Up Self-Test  
ASMi-52 performs a hardware self-test upon power-up. The self-test sequence  
checks the critical circuit functions of the modem.  
The results of the hardware self-test for the local or remote ASMi-52 are displayed  
in the System Status and Physical Status Port screens (see Chapter 4).  
Front Panel LEDs  
The status of ASMi-52 is indicated by the ALM, TST and SYNC LED indicators  
located on the front panel. For the description of LEDs and their functions, refer to  
Chapter 3.  
6.3 Handling Alarms  
ASMi-52 detects fault conditions and initiates alarms to alert the user. ASMi-52  
supports the following alarm types:  
•
•
•
•
System alarms, relating to the ASMi-52 chassis  
Port alarms, relating to a specific interface (SHDSL or DTE)  
Information messages (warnings)  
Events that trigger alarm activation.  
ASMi-52 maintains two separate displays for the system and port alarms. In  
addition, the modem supports a local log file, holding up to 100 alarms.  
An alarm or warning simultaneously activates the alarms display and generates a  
log file, and the ALM LED turns on to indicate the condition. When the fault  
condition that caused the alarm is cleared, the alarm is removed from the alarm  
screen, but remains in the log file, enabling you to view the alarm history. Events  
are generated into the log file.

data flow.  
Note  
•
•
Both local and remote ASMi-52 units must be configured and synchronized  
properly to allow remote loopback activation.  
Only one loopback can be activated at a time, either on the local or remote  
unit.

Running the Local Loopback  
The local loopback (LLB) checks the performance of the local ASMi-52 modem,  
the local DTE and the connection between them (see Figure 6-21). The LLB can be  
performed separately on the local and remote modems.  
ASMi-52 allows you to set the loopback timeout causing the LLB to deactivate  
automatically after the required period of time.  
Note  
Timeout set to 0 (zero) is forever. Avoid setting timeout to 0 as the local control is  
lost during LLB.

6.6 Frequently Asked Questions  
Question: In which cases is it not possible to loop the ASMi-52 modem via the  
diagnostic screen?  
Answer: There are two possible reasons why the loops options do not appear in  
the diagnostic screen:  
1. The modem has an ETH interface, and since there are no loops in ETH, this  
option does not exist.  
2. When two modems are connected back-to-back and one of them is in loop  
mode, the other modem cannot access the loop options.  
Question: What are the different types of SHDSL mapping supported by RAD  
products?  
Answer: There are 3 modes of transferring user data over SHDSL:  
ꢀ Serial ATM  
ꢀ Slotted E1  
ꢀ
n × 64  
Since SHDSL defines its own framing, the data must be "converted" to one of the  
three framing types defined above. Serial ATM uses ATM features (ATM cells,  
UVR, VBR, CBR, and so on); while slotted E1 defines timeslots as the timeslots  
used for E1 Tx (up to 2048 kbps). Finally, n × 64 defines the data rate of the serial  
port data in steps of 64 kbps, starting from 64 kbps, and ending in 4.6 Mbps.

IR-IP Interface Module  
B.1 Introduction  
Overview  
IR-IP is a high-performance, miniature IP router based on RAD's unique IP router  
chip, the Chip Router. IR-IP has a 10BaseT (UTP) interface and complies with  
IEEE 802.3. The router interface operates in either half-duplex or full-duplex  
mode.  
IR-IP filters the traffic, in accordance with the IP address of each packet, and  
forwards only packets with foreign addresses through the WAN link. IP packets  
received from the link are automatically forwarded to the LAN connected to the  
local Ethernet interface if the IP net matches.  
IR-IP includes hardware filters which handle all filtering operations at wire speed  
from both LAN-to-WAN and WAN-to-LAN, without dropping a single packet.  
Filtering and forwarding are performed at the maximum rate of 35,000 and  
30,000 frames per second (wire speed), respectively. The buffer can hold  
256 frames of maximum size of 1534 bytes and a throughput latency of one  
frame.  
ASMi-52 equipped with IR-IP interface module can be used as a Frame Relay  
Access Device (FRAD) with an integral IP router. RFC 1490 is supported for a  
single DLCI on the WAN link. Detection of the DLCI and the maintenance  
protocol is performed automatically. This allows the IR-IP to be used as the  
termination unit of IP services over Frame Relay at the customer premises,  
opposite a Frame Relay switch in the backbone.  
Alternatively, Point-to-Point Protocol (PPP) can be run on the WAN link with  
automatic negotiation on power-up, as well as support for PAP and CHAP  
authentication. With this feature, IR-IP can operate opposite any PPP compliant  
access server or backbone router.  
IR-IP supports HDLC-like framing, which is especially important for broadcast and  
multicast applications where bandwidth overhead is critical.  
IR-IP supports IP multicast at wire speed, making it suitable for any multicast  
environment including high speed downstream environments, such as satellite and  
xDSL. Users on the LAN who register with IR-IP for an IP multicast group using the  
IGMP protocol filter IP multicast packets at wire speed.  
Management and advanced configuration are performed via Telnet.

Appendix B IR-IP Interface Module  
B.4 IR-IP Management Subsystem  
The IR-IP interface module management subsystem supports the following  
functions:  
•
•
•
•
•
Preliminary configuration  
Configuration of management access parameters  
Advanced configuration of IR-IP parameters  
Collection and display of statistical performance data  
Maintenance functions, which include:  
ꢀ Software downloading  
ꢀ Resetting of various subsystems  
ꢀ Display of error log  
ꢀ Ping utility, for checking IP connectivity.  
The management subsystem of the IR-IP interface module is a separate,  
independent entity, and therefore it cannot be managed through the ASMi-52  
management subsystem.  
The communication with the IR-IP management subsystem is made through the  
local LAN interface connector of the IR-IP module, designated 10BaseT, using the  
Telnet protocol. Passwords can be used to prevent unauthorized access.  
Accessing the IR-IP Management Subsystem  
The IR-IP interface module must be configured in accordance with the specific  
requirements of the user’s application before it can be used in the user’s network.  
As a result, it is not possible to supply default parameters to enable IR-IP to start  
service without any preliminary configuration.  
Therefore, to enable the user to establish Telnet communication and configure  
IR-IP, IR-IP is delivered with a factory-default set of parameters. The factory-default  
parameters are automatically used:  
•
Before the IP router is configured by the user, e.g., when a new ASMi-52 with  
IR-IP interface module is put into operation  
•
After the user’s configuration parameters have been erased.  
When the factory-default parameters are used, the ERR indicator located on the  
ASMi-52 rear panel, near the IR-IP Ethernet interface connector flashes rapidly  
(about three times per second).  
Note  
The flashing of the ERR indicator also serves as a warning to the user that the IR-IP  
WAN interface does not send, nor does it receive packets, and therefore IR-IP can  
be accessed only from the LAN.

Appendix B IR-IP Interface Module  
Installation and Operation Manual  
After configuring IR-IP, it starts normal operation and routes the traffic in  
accordance with the user-selected configuration parameters.  
To change the parameters of an already-configured IR-IP, establish communication  
from a Telnet host using the assigned IP address.  
Default IP Communication Parameters  
The factory-default IP communication parameters of the interface module are:  
•
•
The default IP address of the IR-IP Ethernet port is 192.168.205.1, and the  
default IP subnet mask is 255.255.255.252.  
The port will accept IP communication only from the IP address  
192.168.205.2. Therefore, as long as the factory defaults are in effect, you  
must assign this address to the Telnet host used to configure IR-IP.  
Using the IP learning mechanism, as explained below you can change the default  
parameters.  
Note  
In the default configuration, the IR-IP WAN interface is disabled. In order to enable  
the WAN interface, you have to modify the Ethernet port address or the IP subnet  
mask.  
B.5 Performing Preliminary Configuration  
The software necessary for performing all the management and configuration  
functions is stored in the IR-IP interface module, and therefore you only need a  
regular Telnet host to perform all the activities described in this appendix.  
A Telnet host is any computer, e.g., an IBM PC or compatible that fulfills the  
following minimum requirements:  
•
•
A standard 10BaseT Ethernet interface  
A TCP/IP protocol stack, and therefore is capable of supporting IP  
communication through the Ethernet interface  
•
•
Telnet client software  
A ping utility.  
Outline of Preliminary Configuration  
ꢀ
To perform the preliminary configuration procedure:  
1. Connect the Telnet host to the IR-IP interface module.  
2. Configure the Telnet host to enable communication with the IR-IP interface  
module using the default IP parameters.  
3. Establish communication with IR-IP and assign the prescribed IP address to its  
LAN interface.  
4. Establish again communication with IR-IP and continue the preliminary  
configuration in accordance with the Quick Setup section below.

Installation and Operation Manual  
Appendix B IR-IP Interface Module  
Connecting the Telnet Host  
Before starting the management and configuration activities, it is necessary to  
establish IP communication between your Telnet host and the IR-IP interface  
module. For this purpose, it is necessary to provide a communication path.  
Because of the method used to assign an IP address to IR-IP Ethernet port, it is  
recommended to connect the Telnet host directly to the IP router 10BaseT  
connector. This is made by connecting an Ethernet cross cable between the  
Ethernet connector of the Telnet host and the IP router connector.  
However, you may also connect through a common LAN: in this case, connect  
your Telnet host and IR-IP to Ethernet hub ports using straight cables.  
Preliminary Telnet Host Configuration  
You can use the IP learning mechanism to configure the IP communication  
parameters of the IR-IP LAN interface. In this case, skip to the Assigning the Router  
LAN Interface Address section below.  
If you prefer to use the factory-default parameters to establish IP communication  
between your Telnet host and IR-IP, configure the Telnet host as follows:  
1. Temporarily configure the host IP address as 192.168.205.2.  
2. The initial destination IP address to be used by the host is 192.168.205.1.  
Note  
The first step in the preliminary configuration process is to assign the desired IP  
address to the LAN interface of the IR-IP interface module.  
After an IP address is assigned and saved, you must change the destination IP  
address of the Telnet host to the new address, otherwise it is not possible to  
continue the configuration process. At the same time, you can also change the  
temporary IP address assigned to the host (192.168.205.2) back to its permanent  
address.  
Assigning the Router LAN Interface Address  
The IP address of the IR-IP LAN interface must be configured as part of the  
preliminary configuration process. To simplify this process, IR-IP includes a simple  
and convenient IP address learning mechanism.  
The IP address can be configured and changed at any time, even after the  
complete IR-IP configuration process has been performed, because it does not  
affect other configuration parameters. Moreover, the IP subnet mask is  
automatically adapted to the new IP address.  
IP Learning Mechanism  
To simplify the configuration process, IR-IP has a special mechanism for  
configuring the IP address of its LAN interface. Setting section 1, called IP address  
learning, of the IR-IP DIP switch (see Table B-2) to ON enables this mechanism.  
The IP learning mechanism enables IR-IP to learn its LAN interface IP address by  
receiving frames sent by a ping utility to the prescribed LAN IP address.

Appendix B IR-IP Interface Module  
Installation and Operation Manual  
Note  
To use the IP learning mechanism, you do not need to know the current address of  
IR-IP LAN interface, but only the prescribed IP address.  
The IP address is actually retrieved from the ARP frames sent during pinging to  
locate the ping destination, not from the ping frames.  
To ensure that the process is correctly performed, it is recommended to check the  
contents of the ARP table before starting the ping utility, to make sure that it does  
not contain the address to be assigned to the IP router LAN interface.  
ꢀ
To view and edit the ARP table contents:  
If the Telnet host you are using runs under Microsoft Inc. Windows™ 95, 98 or  
NT, use the following procedure to view and edit the ARP table contents:  
1. Display the table using the arp -acommand.  
2. If the table includes the intended IP address, remove it from the table using  
the arp -dcommand.  
If for some reason the IP learning process does not succeed, before repeating it,  
make sure to remove the IP address from the table.  
Assigning a LAN IP Address to a New IR-IP  
The following procedure enables you to configure the LAN IP address of a new  
IR-IP router, i.e., a router using the default parameters (see the Accessing the IR-IP  
Management Subsystem section above).  
If ASMi-52 is already operating, skip Step 2 in the following procedure.  
ꢀ
To configure the IP router LAN address:  
1. Make sure the preparations described above have been completed, including  
the configuration of the ping utility.  
2. Turn ASMi-52 on and monitor the IP router indicators:  
ꢀ The LINK indicator turns on  
ꢀ The ERR indicator lights steadily for approx. 15 seconds, and then starts  
flashing at a rapid rate (about three times per second).  
If the ERR indicator turns off, skip to the section below.  
3. Set section 1 of IR-IP DIP switch to ON.  
The ERR indicator starts flashing faster (approximately four times a second).  
4. Send a ping to the new address to be used by IR-IP. A confirmation should be  
received after the third ping: after the confirmation, the flashing will slow  
down to approximately twice a second.  
If your host does not begin to receive ping replies after three unsuccessful  
attempts, skip to the section below.  
5. Return section 1 of the IR-IP DIP switch to the OFF position.  
The ERR indicator must turn off.

Installation and Operation Manual  
Appendix B IR-IP Interface Module  
At this stage, the communication with IR-IP router is lost, because its IP address  
has been changed. Therefore, you must reconfigure the destination IP address of  
the Telnet host. If you wish, you may also change the temporary IP address  
assigned to the host (192.168.205.2) back to its permanent address.  
Changing the LAN IP Address of a Configured IR-IP  
The LAN IP address of an already-configured IR-IP can be changed while it  
operates. This means it is not necessary to turn ASMi-52 off before starting the  
configuration procedure. Note however that the IP traffic flow through IR-IP will  
be disrupted until the other stations in the IP network learn the new address.  
To change the LAN IP address of an already-configured IR-IP, use the procedure  
described above for a new IR-IP with the following differences:  
•
Configure the destination address of the ping utility to the new LAN interface  
IP address. It is not necessary to change the Telnet host source address.  
•
•
•
When ready, set section 1 of the IR-IP DIP switch to ON.  
The ERR indicator starts flashing faster (approximately four times a second).  
Perform steps 4, 5 of the procedure used for a new IR-IP.  
B.6 IR-IP Management Utility  
General Operating Procedures  
The IR-IP interface module is managed via a simple, menu-driven utility that uses a  
basic terminal user interface. A typical screen is shown in Figure B-3.  
As seen in Figure B-3, each screen has a header that identifies the device being  
configured and its logical name, assigned by the user, followed by the running  
software revision and date. The bottom line of the screen displays prompts that  
guide you in the execution of the various activities.  
Use the following general procedures to perform the desired activity:  
•
To change a parameter or to select a menu item, type the corresponding line

LAN IP Address – The LAN IP address for the IP router LAN interface, is the address to  
which nodes connected to the local LAN send packets that are addressed  
to the WAN.  
LAN IP Mask – Used to enter the IP subnet mask. The IP router supports a maximum of  
254 hosts on the LAN, therefore you must use Class C subnet masks. The  
basic subnet IP mask for Class C addresses, which supports the maximum  
possible number of hosts, 254, is 255.255.255.0. To help you understand  
the selection of IP subnet masks, Figure B-6 provides a configuration  
example for a LAN with 6 nodes: the IP subnet mask for a 6-node IP  
network is 255.255.255.248.

Installation and Operation Manual  
WAN IP Address – Used to enter the IP address for the IR-IP WAN interface, i.e., the IP  
address to be used by IP hosts on the WAN to reach this IR-IP interface  
module.  
If the WAN IP Address field remains blank, IR-IP operates in the  
Unnumbered Router Mode.  
WAN IP Mask – Used to enter the IP subnet mask for the WAN interface.  
Default Gateway:  
Operation without Default Gateway  
The IP interface module is intended to enable the extension of LANs  
through the  
ASMi-52 link. Therefore, its default routing operation is different from the  
default routing operation of standard IP routers:  
ꢀ
IR-IP forwards packets with destinations not located on the local LAN  
through the WAN interface  
ꢀ
Packets received from the WAN interface and destined to hosts  
located on the local LAN are forwarded to the LAN; other packets are  
discarded.  
The default operation is used when the Default Gateway field is blank.  
Operation with Default Gateway  
You can instruct IR-IP to send packets with destinations not located on the  
local LAN to a specific router, which is called the default gateway. The  
default gateway must be connected to the local LAN.  
To use this option, enter the IP address of another router attached to the  
local LAN in the Default Gateway field.  
Note  
It is very important to obtain the correct parameters from the system administrator  
or ISP. The most common problem when establishing an IP connection is incorrect  
configuration of IP parameters and default gateway. Do not try to guess these  
parameters.  
DHCP Relay – IR-IP can operate as a DHCP relay for computers on its LAN. In this  
mode, the user does not need to configure the IP addresses and other  
related parameters for the PCs on the LAN: they receive the configuration  
from the DHCP server via the IR-IP module.

Defining a Telnet Password  
By default, management access to IR-IP via Telnet is unrestricted. To restrict  
access, enter a Telnet password by selecting 1 in the Management Access menu.  
The password can include up to 10 characters, and is case-sensitive. The next time  
a Telnet session is opened, a password must be entered to enable you to access  
the IR-IP menus.  
At any time, only one Telnet connection to IR-IP is permitted. Any attempt to  
open an additional connection while the current session is open is rejected.  
Setting Telnet Inactivity Timeout  
This parameter specifies the time a Telnet session is kept open when there is no  
keyboard activity. When the specified time-out expires, the Telnet session is closed  
and another user can access IR-IP.

Installation and Operation Manual  
B.13  
Erasing User’s Configuration  
The user-defined configuration parameters are stored in the IP router card flash  
memory. After the user-defined configuration parameters are erased, the IP router  
card automatically loads the default parameters.  
You may want to erase the current configuration parameters:  
•
•
Before IR-IP is prepared for operation in a new application.  
When you cannot configure IR-IP because its current LAN-interface IP address  
and/or the Telnet password, are not known.  
ꢀ
To erase the user’s configuration:  
1. Turn ASMi-52 off.  
2. Set all the four sections of the IR-IP DIP switch (see Table B-2) to ON.  
3. Turn ASMi-52 on and monitor the ERR and LINK indicators: they must blink  
alternately.  
4. While ERR and LINK are blinking (within 15 seconds), set sections 1 and 2 of  
the DIP switch to OFF.  
The IP router configuration is erased. During the process of erasing, the  
ERR indicator turns on and lights steadily.  
Note  
If you do not set sections 1 and 2 to OFF within 15 seconds of power-up, the IP  
router card ignores the setting of all the four sections to ON and starts normal  
operation. In this case, it is recommended to turn ASMi-52 off and then back on.  
To abort the whole operation, turn ASMi-52 off, return all the four-switch section to  
the desired positions, and then turn ASMi-52 on again.  
5. Turn ASMi-52 off, and then return all the four sections of the DIP switch to the  
desired positions.  
B.14  
Erasing IR-IP Software  
You may erase the IR-IP application software, without erasing the user-defined  
parameters.  
After the application software is erased, IR-IP starts its TFTP server application, and  
waits for the downloading of software by a TFTP client connected to its LAN  
interface. The procedure to be used to download the application software in this  
case is also described below.  
You may want to erase the application software if the downloading of new  
software using the Device Control menu (see Figure B-15) fails, and the IP router  
card does not function properly.

Erasing Application Software  
ꢀ
To erase the application software:  
1. Turn ASMi-52 off.  
2. Set all the four sections of IR-IP DIP switch to ON.  
3. Turn ASMi-52 on and monitor the ERR and LINK indicators: they must blink  
alternately.  
4. While ERR and LINK are blinking (within 15 seconds), set sections 3 and 4 of  
the DIP switch to OFF.  
The IP router application software is erased. During the process of erasing,  
the ERR indicator turns on and lights steadily.  
Note  
If you do not set sections 3 and 4 to OFF within 15 seconds of power-up, IR-IP  
ignores the setting of all the four sections to ON and starts normal operation. In this  
case, it is recommended to turn ASMi-52 off and then back on.  
Alternately, to abort the whole operation, turn ASMi-52 off, return all the four  
switches to the desired positions, and then turn ASMi-52 on again.  
5. Turn ASMi-52 off, and then return all the four sections of the DIP switch to the  
desired positions.  
Downloading New Software  
After erasing the application software, you can download new software from any  
computer that can serve as a TFTP client.  
To enable the downloading, IR-IP automatically activates its TFTP server  
application with the following factory-default IP parameters:  
•
•
IP address:  
192.168.205.1  
Subnet mask:  
255.255.255.252.  
Connect the computer serving as a TFTP client to the IR-IP 10BASE-T connector in  
the way as a Telnet host used for preliminary configuration (see the Performing  
Preliminary Configuration section). The computer IP parameters must be  
configured as follows:  
•
•
•
IP address  
192.168.205.2  
255.255.255.252  
192.168.205.1  
Subnet mask  
Default gateway  
ꢀ
To download new software:  
1. If necessary, turn ASMi-52 off.  
2. Set all the four sections of the IR-IP DIP switch to OFF.  
3. Turn ASMi-52 on.  
4. Connect the computer to the IP router LAN interface (for the 10BaseT version,  
verify that the LINK indicator lights steadily) and configure its IP parameters as  
explained above.

5. Run a standard TFTP client application on the Telnet host, and download the  
appropriate software file.  
ꢀ If the download is successful, IR-IP starts using the new software.  
ꢀ If the downloading fails, repeat the download process.  
B.15  
IR-IP Troubleshooting  
ꢀ
What if the LINK indicator (10BaseT version) does not light immediately after  
ASMi-52 is turned on?  
The IR-IP interface module does not receive power from the ASMi-52 power  
supply. Service is required.  
Note  
After the power-up process ends, the LINK indicator shows LAN integrity. It may  
stay turned off without indicating power supply failure.  
ꢀ
ꢀ
What if the ERR indicator does not light immediately after ASMi-52 is turned  
on?  
IR-IP is faulty and must be replaced.  
What if the ERR indicator lights for 15 seconds after turning it on and then  
turns off. ACT lights from time to time, but there is no response from IR-IP?  
One of the following:  
No software loaded into IR-IP. Download software.  
IR-IP has been configured. If you do not know the current IP address of the LAN  
interface, erase IR-IP router configuration using the procedure given in the  
section below.  
ꢀ
ꢀ
What if there are no ping replies from IR-IP?  
If your host does not begin to receive ping replies after three unsuccessful  
attempts, check the physical connection path between the Telnet host Ethernet  
interface and the IR-IP 10BaseT connector.  
What to do if the IP learning process is not successful?  
Check that the prescribed IP address does not appear in the ARP table.
