CANADIAN EQUIPMENT LIMITATIONS  
Notice: The Canadian Industry and Science Canada label identifies certified  
equipment. This certification means that the equipment meets certain telecom-  
munications network protective, operational, and safety requirements. The  
Department does not guarantee the equipment will operate to the user's satisfac-  
tion.  
Before installing this equipment, users should ensure that it is permissible to be  
connected to the facilities of the local telecommunications company. The equip-  
ment must also be installed using an acceptable method of connection. In some  
cases, the company's inside wiring associated with a single line individual  
service may be extended by means of a certified connector assembly (telephone  
extension cord). The customer should be aware that compliance with the above  
conditions may not prevent degradation of service in some situations.  
Repairs to certified equipment should be made by an authorized Canadian  
maintenance facility designated by the supplier. Any repairs or alterations made  
by the user to this equipment, or equipment malfunctions, may give the telecom-  
munications company cause to request the user to disconnect the equipment.  
Users should ensure for their own protection that the electrical ground connec-  
tions of the power utility, telephone lines and internal metallic water pipe  
system, if present, are connected together. This precaution may be particularly  
important in rural areas.  
Users should not attempt to make such connections themselves, but  
should contact the appropriate electric inspection authority, or an  
electrician, as appropriate.  
The Load Number (LN) assigned to each terminal device denotes the percentage  
of the total load to be connected to a telephone loop which is used by the device,  
to prevent overloading. The termination on a loop may consist of any combina-  
tion of devices subject only to the requirement that the total of the Load Num-  
bers of all devices does not exceed 100.

Introduction  
PRODUCT OVERVIEW  
The ADTRAN IQ Probe provides the visibility and control  
needed for both the physical and logical connections made in  
frame relay networks. The IQ Probe provides logical layer  
monitoring and management for frame relay. Each permanent  
virtual circuit (PVC) accessed through an IQ Probe is managed  
end-to-end as if it were a leased line connection. Real-time  
statistics on throughput, bandwidth utilization, availability,  
bursting, congestion, and network delay are collected and  
stored. The statistics are viewable through the IQ Probe using  
the front panel, the VT 100 interface, or the Frame IQ MIB  
(management information base). This information can be  
gathered by management systems via SNMP (simple network  
management protocol) and used to monitor network health and  
perform long-term network planning.  
The unit's embedded SNMP agent provides complete SNMP  
access to the unit. SNMP access is available through the DTE or  
DCE port or through an integral SLIP (serial line internet  
protocol) or PPP (point-to-point protocol) async port. The IQ  
Probe also provides integrated 10baseT ethernet access for  
SNMP.  
The following are features of the IQ Probe:  
• Complete and comprehensive frame relay monitoring  
• Real-time measurement of bandwidth utilization, committed

popular enterprise reporting systems  
• Optional IQ View™ software system provides a cost-effective,  
easy-to-use GUI (graphical user interface) for performance  
management  
• DTE (data terminal equipment) and DCE (data communica-  
tions equipment) interfaces support interface standards of  
EIA-232, V.35, X.21, and EIA-530  
UNDERSTANDING FRAME RELAY  
Frame relay is a wide area network (WAN) service designed to  
minimize physical connections. This is accomplished by using  
virtual connections within the frame relay cloud and accessing  
these virtual circuits with normally one physical connection at  
each location to the frame relay service. Virtual circuits are  
addressed using header information at the beginning of each  
frame. These frames are formatted by a device such as a router  
or FRAD (frame relay access device) and monitored by the IQ  
Probe.  
ANSI (American National Standards Institute) standards de-  
scribe how each frame must be constructed to provide interoper-  
ability between CPE equipment and frame relay switching  
equipment. Each frame must contain a header, at least one byte  
of information data, two bytes of CRC16, and a trailing flag  
0x7E.

Chapter 1. Introduction  
This header information contains a virtual circuit address known  
as a DLCI (data link connection identifier). The header informa-  
tion also contains bits used for network congestion control.  
Frame relay virtual circuits may be defined as permanent (PVC)  
or switched (SVC). PVCs have the same DLCI for a given path  
each time a user protocol session is established. The network  
service provider assigns these DLCIs at subscription time. SVCs,  
on the other hand, have DLCIs dynamically assigned each time a  
user protocol session is established. The CPE equipment must  
request a call and the DLCI is assigned by the network switching  
equipment. This DLCI is valid until the call is disconnected and  
may be assigned a different value each time a call is requested.  
SNMP MANAGEMENT  
SNMP management capability is provided in-band with support  
for RFC 1315 (frame relay DTE MIB), RFC 1213 (MIB II), and  
ADTRAN Enterprise MIB. MIB files are available from  
ADTRAN in the support section of the ADTRAN Web page at  
www.adtran.com. TELNET capability is also supported. For  
non-TCP/ IP environments, VT 100 and front panel operation are  
supported.  
The IQ Probe's embedded SNMP feature allows the unit to be  
accessed and controlled by a network manager in-band at the  
DTE or DCE interface, out-of-band at the control port via SLIP or  
async PPP, or using a LAN connection.  
The term SNMP broadly refers to the message protocols used to  
exchange information between the network and the managed  
devices, as well as to the structure of network management data  
bases. The three basic components of SNMP follow:  
Network Manager  
Control program that collects, controls, and presents data  
pertinent to the operation or management of the network  
devices. It resides on a network management station.

Chapter 1. Introduction  
Agent  
Control program that resides in each connected network device.  
This program responds to queries and commands from the  
network manager and returns requested information or invokes  
configuration changes initiated by the manager.  
MIB  
Index to the organized data within a network device. It defines  
the operation parameters that can be controlled or monitored.  
TELNET  
TELNET provides a password-protected, remote login facility to  
the IQ Probe. TELNET allows a user on a network manager to  
control the IQ Probe through the terminal menus.  
DIAL BACKUP OPERATION  
The IQ Probe dial backup (DBU) option cards allow frame relay  
circuit outage recovery for one user-to-network interface (UNI)  
at a time. The IQ Probe can be configured to originate a call  
based on physical layer conditions and/ or PVC signaling loss.  
Once the criteria are met, the IQ Probe establishes a call to the  
configured phone number and the connection is used to carry  
traffic for the PVC(s) configured for DBU operation.  
These cards allow the unit receiving the call to continue to use  
the network frame relay circuit for PVCs that are not affected by  
the outage, while using the DBU interface for PVCs that are  
inactive due to the outage. An IQ Probe with multiple PVCs to  
multiple sites can also originate a call to one site during an  
outage and restore connection for PVCs to that destination.  
The cards are field-installable by the customer. See the chapter  
Installation for information on installing DBU cards. The DBU  
cards are compatible with other ADTRAN ESP products  
supporting DBU. The backup options are described in the  
following section, ESP Card Options. Contact the local telco  
provider to determine which services are available in your area.  
See the chapter Applications for more information, including an  
example of a dial backup application.

Applications  
This chapter provides examples of some common IQ Probe  
management options as well as an example of a dial backup  
application. The management application examples include  
VT 100 management, out-of-band SNMP/ TELNET management,  
and in-band PVC SNMP/ TELNET management. Descriptions  
and configuration tips for these options are provided in the  
sections that follow.  
The application drawings in this chapter show routers as the frame  
relay device. The frame relay device could be any device with frame  
relay capabilities. However, to use in-band management, the manage-  
ment DLCI must be RFC 1490 encapsulated IP traffic.  
MANAGEMENT APPLICATIONS  
One of the main advantages of the IQ Probe is management  
flexibility. The IQ Probe front panel interface provides complete  
configuration capabilities and viewing of key frame relay  
statistics information. Other management options described in  
this chapter provide configuration and diagnostics capabilities as  
well as all-inclusive statistics information.

Local VT 100 Terminal Management  
Connect a VT 100 terminal to the IQ Probe CONTROL port.  
This interface provides full-screen configuration and all-inclu-  
sive statistics access. VT 100 management also allows for remote  
configuration. Through this port, a remotely located ADTRAN  
IQ device is fully accessible for configuration, diagnostics, and  
statistics viewing. Figure 4-1 gives an example of a VT 100  
application.  
VT 100 remote mode is proprietary and non-intrusive. Therefore, you  
can perform all VT 100 management functions without disrupting the  
flow of data.

Control Port Mode  
Set the Control Port Mode for TERMINAL (which is the default  
setting). This selection is found in the SYSTEM portion of the  
CONFIGURATION menu (SYSTEM -> CONTROL PORT  
OPTIONS -> CONTROL PORT MODE).  
Out-of-Band Management  
This management option (shown in Figure 4-2) is commonly  
used in situations where the customer is trying to reduce the  
amount of management traffic flowing through the frame relay  
device. The IQ Probe can be managed though an established  
TELNET session or an SNMP-based network manager like HP  
OpenView®, IBM Netview®, or SunNet Manager®.  
The ADTRAN IQ Probe MIB is available in the support section of the  
ADTRAN Web page at www.adtran.com.  
SNMP and TELNET management is provided by one of the  
following interfaces:  
• A device (e.g., a router) running SLIP protocol. Connection is  
made through the IQ Probe's control port.  
• A device (e.g., a router) running async PPP protocol. Connec-  
tion is made through the IQ Probe's control port.  
• A LAN. Connection is made through the 10baseT ethernet  
interface.

In-Band Management  
The ADTRAN IQ Probe supports three modes of in-band  
management using the frame relay structure of PVCs. These  
modes are local (see Figure 4-3), shared (see Figure 4-4), and  
dedicated PVC management (see Figure 4-5). All three types  
support complete SNMP management as well as TELNET  
capabilities.

IQ Probe User Manual

Chapter 4. Applications  
All PVC-based in-band management traffic must be noncompressed IP  
and use RFC 1490 encapsulation.  
Local PVC Management  
Local PVC management refers to a PVC created between the IQ  
Probe and the frame relay router on the DTE interface of the IQ  
Probe. This type of management is ideal when local manage-  
ment is needed but an ethernet connection is not available. To  
support this type of management, all traffic on the selected PVC  
must be RFC 1490 encapsulated, noncompressed IP traffic.  
The local PVC is sent out of the WAN serial port of the router as  
normal WAN traffic and is terminated in the IQ Probe. Since the  
IQ Probe responds to Inverse ARP, it is not necessary to set up a  
static route in the router. The router will discover the IP address  
automatically; however, it will be necessary to set up a local PVC  
between the router and the IQ Probe. Accomplish this by setting  
a value (between 16 and 1007) for the DTE management DLCI on  
the IQ Probe to a value not used by the frame relay network.  
Local PVC management can be used at any location that has a  
router. Therefore, remote sites can be accessed through the  
remote router. One consideration when using local PVC man-  
agement is that if the remote router goes down, access to the  
remote IQ Probe is lost.

Shared PVC Management  
Shared PVC management refers to a PVC that is used for normal  
data traffic between locations. The IQ Probe monitors this PVC  
for packets that contain its IP address. When the IQ Probe  
detects a packet containing a destination IP address that matches  
the IQ Probe IP address, the unit intercepts the packet and  
processes its TCP/ IP information. To support this type of  
management, all traffic on the selected PVC must be RFC 1490  
encapsulated, noncompressed IP traffic.  
Shared PVC management is used to manage remote ADTRAN  
IQ devices without being dependent on services from the remote  
router. This usually requires a static route at the host location.  
By setting a local PVC management and shared PVC management on  
the remote IQ Probe, its IP address can be found through Inverse ARP.

Dedicated PVC Management Application  
Minimum Configuration Requirements for Dedicated PVC  
Management  
The configuration requirements for dedicated PVC management  
are identical to those listed for shared PVC management. See the  
previous section, Minimum Configuration Requirements for Shared  
PVC Management, for more information.  
DIAL BACKUP APPLICATION  
The IQ Probe dial backup (DBU) options allow frame relay  
circuit outage recovery for one user to network interface (UNI) at  
a time. Therefore, if the host site goes down, only one remote  
site (the primary remote) is backed up. The IQ Probe can be  
configured to originate a call based on physical layer conditions  
and/ or PVC signaling loss. Once the criteria are met, the IQ  
Probe establishes a call to the configured phone number (see  
Table 4-A) and the connection is used to carry traffic for the  
PVC(s) configured for DBU operation.  
61200214L1-1  
IQ Probe User Manual  
33  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Chapter 4. Applications  
During dial backup, the IQ device receiving the call continues to  
use the frame relay circuit for PVCs that are not affected by the  
outage, while using the DBU interface for PVCs that are inactive  
due to the outage. This is done (without the attached DTE  
device's intervention) by modifying the status of PVCs that are  
in DBU state to active when the PVC status is given to the DTE.  
An IQ Probe with multiple PVCs to multiple sites can also  
originate a call to one site during an outage and restore connec-  
tion for PVCs to that destination. Since the IQ Probe can only  
make one call at a time, the other PVCs to other sites in this  
scenario will be inactive.  
Information entered into the PVC Configuration Table (see Table  
4-B) marks PVCs for DBU operation. The key element in each  
entry of the table is the DBU DLCI. For each PVC connecting  
two sites for DBU operation, the DLCI field represents the PVC  
DLCI at the local UNI and the DBU DLCI represents the PVC  
DLCI at the remote site UNI. The IQ Probe uses this information  
in the outbound side to change the PVC DLCI so the far end  
DTE device receives frames on the DBU PVC addressed in the  
same manner as when the frame relay circuit is operational. For  
PVCs not used for DBU operation, leave the DBU DLCI field set  
to zero.  
The DBU DLCI information is only required for the IQ Probe  
originating the call. In cases such as remote sites establishing  
calls to host sites, the remote site should have only non-zero  
values for the DBU DLCI fields in the PVC Configuration Table.  
Only PVCs that are used in DBU should have the DBU DLCI set to a  
non-zero value.  
The range for the DBU DLCI field is from 16-1007. Therefore,  
you cannot manually enter 0 for the PVCs not used in DBU.  
When an entry is first created with the ADD selection, it is set to  
0 by default. To reset a previously configured DBU DLCI to 0,  
delete the entry and then add it back in (using the DELETE and  
ADD selections).

None  
No flow control is used and the IQ Probe drops frames during  
severe congestion while in DBU operation.  
Hardware  
The IQ Probe varies the DTE TC clock as necessary to relieve  
congestion during DBU operation.  
FECN/BECN  
While in a congested state during DBU operation, frames across  
the DBU PVCs have FECN or BECN set depending on the  
direction. Frames outbound to the network have FECN set,  
while frames inbound to the attached DTE device have BECN  
set. This method is useful if the attached DTE devices can  
respond to congestion notification.  
CTS Option  
DSR Option  
CD Option  
Set the CTS lead to FORCED ON or FOLLOW RTS.  
Forced On  
The CTS lead is always on and the RTS lead is ignored.  
Follow RTS  
The CTS lead is on when the RTS lead is on (and off when the  
RTS lead is off).  
Set the DSR lead to FORCED ON or NORMAL.  
Forced On  
The DSR lead is always on.  
Normal  
The DSR lead is off when the IQ Probe does not receive DSR  
from the DSU/ CSU on the DCE port.  
Set the CD lead to FORCED ON or NORMAL.

Chapter 6. DTE Port Configuration  
Forced On  
The CD lead is always on.  
Normal  
The CD lead is off when the IQ Probe does not receive CD from  
the DSU/ CSU on the DCE port.  
TC Clock Option (TC CLOCK OPT)  
Normal  
Clock for DTE's transmit data normal phase.  
Inverted  
Clock for DTE's transmit data inverted phase. May be used in  
high speed circuits (>512 kbps) when the DTE's V.35 interface  
has high delay. This is usually indicated by HDLC errors on the  
IQ Probe's DTE port.  
Frame Relay Options (FR OPTS)  
These selections apply to the signaling between the router or  
FRAD and the IQ Probe DTE port.  
T392  
Set the timeout (in seconds) between polling intervals. This  
parameter needs to be a few seconds longer than the T391 setting  
of the attached frame relay device.  
N392 and N393  
These parameters define the error threshold for the UNI (user to  
network interface) formed by the IQ Probe DTE port and the  
attached frame relay device. If the error threshold is met, the  
signaling state status is changed to down, which indicates a  
service-affecting condition. This condition is cleared once N393  
consecutive error-free events are received. N392 defines the  
number of errors required in a given event window, while N393  
defines the number of polling events in each window.

Chapter 6. DTE Port Configuration  
For example:  
If N392=3 and N393=4, then if three errors occur within any four  
events, the interface is determined inactive.  
The status of the connection can be viewed in the Status menu  
under DTE Port Signaling State. The status will return to active  
once the threshold is no longer exceeded.  
Management DLCI (MGMT DLCI)  
To use local PVC management, enter the management data link  
connection identifier (DLCI). The management DLCI is a special  
DLCI used between the attached DTE device and the IQ Probe to  
carry SNMP and TELNET packets to/ from the IQ Probe on the  
DTE port.  
Guidelines for Configuring Management DLCI  
If the attached router or FRAD is used to route SNMP/ TELNET  
frames to the IQ Probe, set the Management DLCI to a unique  
value (between 16 and 1007) that identifies the virtual circuit  
between the router/ FRAD and the IQ Probe. The router/ FRAD  
must also be configured to route the IQ Probe IP address to this  
DLCI. The IP address and subnet mask for the DTE port must  
also be set in the System Configuration menu.  
Management PVC Option (MGMT PVC OPT)  
If this option is set to ENABLED, the management DLCI is  
included in the Full Status response to the router. Enable this  
option when the management DLCI is used to route manage-  
ment traffic to the IQ Probe.  
Signaling Responses (SIG RESPONSES)  
This option determines when PVC signaling responses are sent  
to the router.  
Always On  
If ENABLED, PVC signaling responses are sent to the router  
regardless of the network signaling state. Enable this option  
when the IQ Probe is used for dial backup.

Follows Network (FOLLOW NET)  
If ENABLED, PVC signaling responses are sent to the router  
only when the network signaling state is up. Enable this option  
when the router is going to use an alternate path for dial backup.

Configuring the DCE Port  
DCE PORT  
Access the DCE port menus by selecting DCE PORT from the  
Configuration menu. Full menu trees for the DCE Configuration  
selections are shown in Figures 5-2 (Terminal Configuration Menu  
Tree) and 5-3 (Front Panel Configuration Menu Tree) of the Configu-  
ration Overview chapter. The DCE port terminates the user end  
of the frame relay UNI interface. The IQ Probe supports three  
standard PVC signaling formats: LMI (gang of four), ANSI  
T1.617-D (Annex D), and ITU Q.933-A (Annex A). The selected  
signaling format is used to poll the DCE end of the UNI interface  
and retrieve virtual circuit information. Optionally, the polling  
process can be disabled.  
When configuring from a terminal, the screen in Figure  
7-1 will appear when DCE Port is selected.  
In this chapter, the terminal selections are listed first followed by the  
Front Panel selections in parenthesis (if the names differ).

Set the signaling type option to match the DCE signaling type.  
Choices are none, LMI (gang of four), ANSI T1.617-D (Annex D),  
ITU-T Q.933-A (Annex A), or auto. AUTO mode forces the IQ  
Probe to use the same signaling type as the attached frame relay  
DTE. If AUTO is selected and there is no DTE device attached,  
the IQ Probe uses ANSI T1.617-D signaling type.

N391  
Determine how many link integrity polls occur in between full  
status polls.  
N392 and N393  
These parameters define the error threshold for the UNI formed  
by the IQ Probe DCE port and the frame relay switch. If the  
error threshold is met, the signaling state status is changed to  
down, which indicates a service-affecting condition. This  
condition is cleared once N393 consecutive error-free events are  
received. N392 defines the number of errors required in a given  
event window, while N393 defines the number of polling events  
in each window.  
For example:  
If N392=3 and N393= 4, then if three errors occur within any four  
events the interface is determined inactive.  
The status of the connection can be viewed in the Statistics menu  
under DCE Port Signaling State. The status will return to active  
again once the threshold is no longer exceeded.  
The network service provider should recommend the values entered into  
the T391, N391, N392, and N393 fields.  
Management DLCI 1 and 2 (DLCI 1 and 2)  
Enter the management data link connection identifiers (DLCIs).  
These DLCIs are used to carry management traffic to and from  
the network.  
Management DLCI 1 and 2 Mode (DLCI 1 and 2 MODE)  
Set to DEDICATED if the management DLCI is used only to  
manage the IQ Probe (and not used to carry customer traffic). If  
set to DEDICATED, the router is not notified of that DLCI. Set to  
SHARED if the management DLCI is used for carrying customer  
traffic and management data.

Chapter 7. Configuring the DCE Port  
Maximum PVC Count (MAX PVC COUNT)  
Sets the maximum number of PVCs that the IQ Probe will  
monitor for statistical information. This value determines the  
amount of history intervals available for storage. To get the  
maximum amount of statistical history storage, set this value  
equal to the number of PVCs assigned to the frame relay port. A  
smaller value increases history interval count but puts some of  
the PVC statistics into the unknown category.  
History Interval Count (HIST INT COUNT)  
Sets the number of history intervals to store for statistics. His-  
tory intervals are displayed in the View by Interval portions of  
the Statistics menus. These views provide data divided into  
columns grouped by the interval of time selected in the History  
Interval Size field (see the chapter System Configuration for more  
information). The History Interval Count field determines how  
many intervals can be stored at a time. The maximum value  
allowed is affected by the previously mentioned PVC Count  
selection.  
PVC Options (PVC CONFIG)  
The PVC Options table enables optional features such as delay  
measurement for each PVC. DLCI numbers and their corre-  
sponding CIRs are supplied by the service provider.  
When configuring PVC options using the front panel, the Next, Prev,  
Add, and Delete keys are used. See the chapter Operation for more  
information on front panel operation.  
DLCI

Only PVCs that are used in DBU should have the DBU DLCI set to a  
non-zero value.  
The range for the DBU DLCI field is from 16-1007. Therefore,  
you cannot manually enter 0 for the PVCs not used in DBU.  
When an entry is first created with the ADD selection, it is set to  
0 by default. To reset a previously configured DBU DLCI to 0,  
delete the entry and then add it back in (using the Delete and  
Add selections/ keys).  
CIR (Kbps)  
Enter the CIR (committed information rate) in kbps for the  
corresponding DLCI. The information is supplied by your  
service provider and must be entered for each PVC to ensure  
accuracy of statistical information.  
Seq Num Checking (SEQ #)  
Set to ENABLE only if there are IQ products on both ends of the  
PVC. When enabled, the IQ Probe tags each frame with a  
sequence number which is then used by the remote IQ device to  
detect lost packets. Lost packet counts are given in the Statistics  
menus.  
Delay Measurement (PVC DELAY)  
Set to ENABLE only if there are IQ products on both ends of the  
PVC. When enabled, the IQ Probe periodically transmits a  
loopback frame to the remote IQ device which is then returned  
to measure round trip delay of each PVC. Minimum, maximum,  
and average delay measurements are given in the Statistics  
menus.

Terminal Statistics Display Options  
DTE port, DCE port, DBU port, and DLCI statistics are given in  
two formats: View by Interval and View by Day.  
View by Interval  
In this view, the first column is a running total for the current  
day. All other columns are grouped into user-configured time  
frames with the most recent information displayed on the left.  
The first column's header displays the current date, and the  
interval columns display the time the intervals began. In order  
to categorize the interval columns by date also, the midnight  
time stamp is replaced with the date. Note that this column still  
represents the timed interval (not a day's worth of information).

Chapter 10. Statistics  
To configure the interval time frame, go to the System Configu-  
ration menu under History Interval Size and select the time you  
want the history interval to be set for (from 5 to 30 minutes, in  
five minute intervals). The IQ Probe gathers and displays the  
information according to the time selected.  
The IQ Probe cuts the first gathering session short in order to begin  
falling on the selected time boundary. For example: If the unit or the  
statistics information was last reset at 12:03 and the History Interval is  
set for five minutes, then the first interval session will last only two  
minutes. Therefore, the first interval column (i.e., the column farthest  
to the right if no columns have been deleted yet) normally represents a  
time shorter than the other columns.  
View by Day  
This view provides historical information for the last seven days  
(not including the current day). The most recent information is  
displayed on the left.  
The first day' s column (i.e., the column furthest to the right) does not  
represent a full day' s worth of information (unless the unit or the  
statistics information was reset at exactly 12 AM).

PVC Loopback  
A PVC loopback test is a non-intrusive loopback option for each  
PVC. During this test, the IQ Probe periodically sends test  
frames to the remote IQ device which are then returned for  
analysis. The bandwidth required is approximately 1 kbps for  
each PVC in test. See Figure 11-3 for the terminal menu.

Glossary  
ANSI  
American National Standards Institute. Devices and proposes recommendations  
for international communications standards.  
ASCII  
American National Standard Code for Information Interchange. The standard  
and predominant 7-bit (8-bit with parity) character code used for data  
communications and data processing.  
asynchronous  
A method of data transmission which allows characters to be sent at irregular  
intervals by preceding each character with a start bit, followed by a stop bit.  
attenuation  
The loss of signal amplitude during transmission. The received signal is lower in  
signal amplitude than the transmitted signal due to losses in the transmission  
medium (resistance in the cable). Attenuation is measured in decibels.  
bandwidth  
The bandwidth determines the rate at which information can be sent through a  
channel (the greater the bandwidth, the more information that can be sent in a  
given amount of time).  
BECN  
backward explicit congestion notification. A bit set by a frame relay network to  
notify an interface device (DTE) that congestion avoidance procedures should be  
initiated by the sending device.

Glossary  
bit  
A binary digit. A signal, wave, or state is represented as either a binary 0 or 1.  
bits per second (bps)  
The number of bits passing a specific point per second. Examples of common  
rates are:  
• A Kilobit is one thousand bits per second (kbps)  
• A Megabit is one million bits per second (Mbps)  
bridge  
A device that supports LAN-to-LAN communications. Bridges may be equipped  
to provide frame relay support to the LAN devices they serve. A frame relay  
capable bridge encapsulates LAN frames in frame relay frames and feeds them to  
a frame relay switch for transmission across the network. A frame relay capable  
bridge also receives frame relay frames from the network, strips the frame relay  
frame off each LAN frame, and passes the LAN frame on to the end device.  
Bridges are generally used to connect LAN segments to other LAN segments or  
to a WAN. They route traffic on the level 2 LAN protocol (e.g. the Media Access  
Control address), which occupies the lower sub-layer of the LAN OSI data link  
layer. See also router.  
byte  
Generally, an 8-bit quantity of information, used mainly in referring to parallel  
data transfer, semiconductor capacity, and data storage. Also, it is generally  
referred to in data communications as an octet or character.  
carrier  
The provider of the data service to the customer site. Carriers can be local  
telephone companies, regional telephone companies or any inter-exchange  
carrier such as AT&T, Sprint, or MCI.  
CD  
carrier detect. A signal generated by a modem or DSU/ CSU. CD indicates the  
presence of a carrier signal on a communications link.  
channel bank  
Equipment in a telephone central office or customer premises that performs  
multiplexing of lower speed digital channels into a higher speed composite  
channel. The channel bank also detects and transmits signalling information for  
each channel; thereby transmitting framing information so that time slots  
allocated to each channel can be identified by the receiver.

Glossary  
CIR  
committed information rate. Less than or equal to the access rate, the CIR is used  
by the service provider for rate enforcement when the network is congested.  
When rates exceed the CIR, frames may be discarded.  
clocking  
An oscillator-generated signal that provides a timing reference for a transmission  
link. A clock provides signals used in a transmission system to control the timing  
of certain functions. The clock has two functions: (1) to generate periodic signals  
for synchronization and (2) to provide a time base.  
control port  
The electrical interface between the IQ Probe unit and a control terminal. The  
control terminal is used to communicate commands to the unit.  
CPE  
customer premise equipment. All telecommunications terminal equipment  
located on the customer premises including telephone sets, private branch  
exchanges (PBXs), data terminals, and customer-owned coin-operated  
telephones.  
C/R bit  
In the Q.921 protocols, a bit that identifies a data-link-layer frame as either a  
command or a response.  
CRC  
cyclic redundancy check. A computational means to ensure the accuracy of  
frames transmitted between devices in a frame relay network. The mathematical  
function is computed, before the frame is transmitted, at the originating device.  
Its numerical value is computed based on the content of the frame. This value is  
compared with a recomputed value of the function at the destination device.  
CS  
See CTS.  
CSU  
channel service unit. A device used to connect a digital phone line coming in  
from the phone company to either a multiplexer, channel bank, or directly to  
another device producing a digital signal (for example: a digital PBX, a PC, or  
data communications device). A CSU performs certain line-conditioning and  
equalization functions and responds to loopback commands sent from the central

Glossary  
office. A CSU regenerates digital signals. It monitors them for problems, and  
provides a way of testing the digital circuit.  
CTS  
clear to send. A signal on the DTE interface indicating that the DCE is clear to  
send data.  
dB  
The standard abbreviation for decibel. A decibel is a unit of measure for signal. A  
decibel is usually the relation between a transmitted signal and a standard signal  
source. Therefore, 6 dB of loss would mean that there is a 6 dB difference  
between what arrives down a communications circuit and what was transmitted  
by a standard signal generator.  
DCE  
data communications equipment. A device that provides all the functions  
required for connection to telephone company lines and for converting signals  
between telephone lines and DTE. Also see DTE.  
DDS  
digital data service. AT&T private line service for transmitting data over a digital  
system. The digital transmission system transmits electrical signals directly,  
instead of translating the signals into tone of varied frequencies as with  
traditional analog transmission systems. Digital techniques provide more  
efficient use of transmission facilities, resulting in lower error rates and costs  
than analog systems.  
DE  
discard eligibility. A user-set bit indicating that a frame may be discarded in  
preference to other frames if congestion occurs, to maintain the committed  
quality of service within the network. Frames with the DE bit set are considered  
Be excess data.  
DLCI  
data link connection identifier. A unique number assigned to a PVC end point in  
a frame relay network. Identifies a particular PVC endpoint within a user's  
access channel in a frame relay network and has local significance only to that  
channel.

DSU  
data service unit. A device designed to transmit and receive digital data on  
digital transmission facilities.  
DTE  
data terminal equipment. The end-user terminal or computer that plugs into the  
termination point (DCE) of a communications circuit. The main difference  
between the DCE and the DTE is that pins two and three are reversed.  
encapsulation  
A process by which an interface device places an end device's protocol-specific  
frames inside a frame rely frame. The network accepts only frames formatted  
specifically for frame relay; therefore interface devices acting as interfaces to a  
frame relay network must perform encapsulation. See also interface device and  
frame-relay-capable interface device.  
end device  
The ultimate source or destination of data flowing through a frame relay network  
sometimes referred to as DTE. As a source device, it sends data to an interface  
device for encapsulation in a frame relay frame. As a destination device, it  
receives de-encapsulated data (i.e., the frame relay frame is stripped off, leaving  
only the user's data) from the interface device.  
far end  
The unit or units not on-site (at the customer's premises or the other end of the  
data link).  
FECN  
forward explicit congestion notification. A bit set by a frame relay network to  
notify an interface device (DTE) that congestion avoidance procedures should be  
initiated by the receiving device. See also BECN.  
file server  
In the context of frame relay network supporting LAN-to-LAN communications,  
a device connecting a series of workstations within a given LAN. The device  
performs error recovery and flow control functions as well as end-to-end  
acknowledgment of data during data transfer, thereby significantly reducing  
overhead within the frame relay network.
