Introduction
PRODUCT OVERVIEW
The ADTRAN TSU IQ+ provides the visibility and control needed
for both the physical and logical connections made in frame relay
networks. The TSU IQ+ provides logical layer monitoring and
management for frame relay. Each permanent virtual circuit (PVC)
accessed through a TSU IQ+ 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 in the Frame IQ MIB
(management information base). Protocol-specific information is
also gathered, providing information concerning traffic utilization
in the frame relay connection. All information can be gathered by
management systems and used to monitor network health and
perform long-term network planning, allowing optimum use of
network resources.
The unit's embedded SNMP (simple network management
protocol) agent provides complete SNMP access to the unit. SNMP
access is available through the DTE or network port or through an
integral SLIP (serial line internet protocol) or PPP (point-to-point
protocol) async port. The TSU IQ+'s unique modular approach
provides optional 10BaseT ethernet access for SNMP.

Chapter 1. Introduction
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 the user's customer premises equipment
(CPE) such as the ADTRAN TSU IQ+.
ANSI (American National Standards Institute) standards describe
how each frame must be constructed to provide interoperability
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.
This header information contains a virtual circuit address known as
a DLCI (data link connection identifier). The header information
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.

Chapter 1. Introduction
T1/FT1 OVERVIEW
The telephone companies (telcos) have used T1 digital
communications links for voice transmission since the early sixties.
The D4 channel bank is an example of a T1 digital carrier system
that was introduced in the mid-seventies and is still widely used by
the telcos. Communication demands of businesses continued to
grow to the point that the telcos began offering T1 service directly
to the public. D4 channel banks began to be used for T1 in
corporate network topographies for voice. The technological
advances in computer development also created a demand for T1
data communication, which now is a large part of the T1 traffic.
T1 Service Offerings
T1 is a digital service that the service providers deliver to the user
over two pairs of wires. The signal operates at 1.544 Mbps and is
usually extended by repeaters that are installed about every mile
after the first 6000 feet. The T1 signal is divided into 24 time slots or
digital signal level zeros (DS0s) which operate at 64 kbps. Each time
slot is occupied by digitized voice or by data.
The T1 signal originally used a type of framing known as D4
superframe which identifies how the T1 is multiplexed. Extended
superframe (ESF) is an enhancement of that framing format. ESF
provides a non-disruptive means of full-time monitoring on the
facility datalink (FDL). The service providers originally used ESF to
monitor the performance of their service offering. Since the
introduction of ESF, equipment that is installed in private networks
can also provide the same performance information to the user.
Fractional T1
Fractional T1 (FT1) lets the buyer purchase less than a full T1 circuit
between two points. Most carriers offer fractional T1 in increments
of 56 or 64 kbps. Connection is made to the same network elements.
The network allows multiple users to share the same interoffice T1
bandwidth.

Chapter 1. Introduction
FT1 remains almost exclusively an inter-exchange carrier (IXC)
service. Local exchange carriers (LECs) typically do not offer FT1,
so the user's proximity to the IXC's point-of-presence (POP) is key
in the savings that fractional T1 offers.
SNMP MANAGEMENT
SNMP management capability is provided in-band with support
for RFC 1315 (frame relay DTE MIB), RFC 1213 (MIB II), RFC 1406
(DS1/ E1 MIB), 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-SNMP environments, VT-100 and front panel operation are
supported.
The TSU IQ+'s embedded SNMP feature allows the unit to be
accessed and controlled by a network manager in-band at the DTE
or network interface, out-of-band at the control port via SLIP or
async PPP, or using a LAN connection. LAN connection requires
the optional ethernet card (P/ N 1204005L1). This card provides a
10BaseT ethernet interface to the LAN.
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 of the network devices. It resides on a network
management station.
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.

Chapter 1. Introduction
TELNET
Telnet provides a password-protected, remote login facility to the
TSU IQ+. Telnet allows a user on a network manager to control the
TSU IQ+ through the terminal menus.
DIAL BACKUP OPERATION
The TSU IQ+ dial backup (DBU) option cards provide single or
multiple sight backup, depending on the DBU card option selected.
The TSU IQ+ can be configured to originate a call based on physical
layer conditions (i.e., port failures) and/ or PVC outages. Once the
criteria are met, the TSU IQ+ establishes a call to the configured
phone number and the connection is used to carry traffic for the
PVC(s) configured for DBU operation.
In the case of PVC outages (not physical layer port failure), the TSU
continue to use the T1 frame relay circuit for PVCs that are not
affected by the outage, while using the DBU interface for PVCs that
multiple sites can also originate a call to one site during an outage
The TSU IQ+'s unique DBU cards are field-installable by the
customer. See Installation on page 2-1 for information on installing
DBU cards. The DBU cards are compatible with other ADTRAN
products supporting DBU. The backup options are described in the
following section, Interface Card Options. Contact the local telco
provider to determine which services are available in your area. See
Applications on page 4-1 for more information, including an
example of a dial backup application.
INTERFACE CARD OPTIONS

Customer Provides
The customer must provide a male V.35 interface cable.
For SNMP management not accessed through the V.35 or Network
port, the customer must provide access to the TSU IQ+ either
through a SLIP, Async PPP (requires a male 25-pin D-type
connector), or a through the 10BaseT Ethernet port (requires that an
ADTRAN Ethernet card be installed in the TSU IQ+). See Pinouts
on page A-1 for the pin assignments of the CONTROL port (for SLIP
and Async PPP) and the ETHERNET port.
Power Up
The TSU IQ+ is provided with a captive 8-foot power cord,
terminated by a three-prong plug which connects to a grounded
115 VAC power receptacle.
Power to the TSU must be provided from a grounded 115 VAC, 60 Hz re-
ceptacle.

DBU and LAN Card Slots
The TSU IQ+ rear panel has two card slots (labeled DBU Interface
and LAN Interface) for the installation of dial backup, ethernet, and
DCE cards. To insert cards, perform the following procedure:
1. On the rear panel, turn off the power switch.
2. Slide the card into the corresponding rear slot until the card
panel is flush with the TSU IQ+ chassis.
3. Push card locks in (until they click) to secure the card and
ensure proper installation.
Card slots are keyed to prevent improper installation (i.e., putting a DBU
card into the ethernet slot). The DCE card is keyed for the DBU slot.
Failure to remove power from the unit before installing or removing op-
tion cards can damage the equipment.
Network Connector
Connect the TSU IQ+ to the network by using the 8-position
modular jack labeled NETWORK. The pinout for this connector is
listed in Pinouts on page A-1.
Test Jacks
Monitor
The monitor jack (labeled MON) is used as a non-intrusive
monitoring point for the data received from the network. The
monitoring device needs to be set for high impedance bridge mode.
In/Out
The IN and OUT jacks are used to connect to a T1 test set for testing
the T1 interface of the TSU IQ+. These connections isolate the T1
interface from the RJ-45 network jack.

DSX-1 Port
The DSX-1 interface provides a short haul T1 connection to a PBX or
other customer premise equipment (CPE). This port complies with
ANSI T1.102.
Control Port
The TSU IQ+ has an 8-pin modular jack labeled CONTROL. The
Control port provides connection to a VT-100 EIA-232 compatible
interface, a device running SLIP protocol, or a device running
Async PPP protocol. An 8-foot cable with adapter connector
provides a standard DB-25 EIA-232 interface. See Pinouts on page
describes this port’s operation.
V.35 Connector
The DTE should be connected to the V.35 connector (labeled V.35
Nx56/64). The maximum cable length is 100 feet. The pin
assignments for this connector are listed in Pinouts on page A-1.
To prevent possible radio frequency interference emissions, a shielded ca-
ble is required.

Applications
This chapter provides examples of some common TSU IQ+
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 capa-
bilities. However, to use in-band management, the management DLCI
must be RFC 1490 encapsulated IP traffic.
MANAGEMENT APPLICATIONS
One of the main advantages of the TSU IQ+ is management
flexibility. The TSU IQ+ front panel interface provides complete
configuration capabilities and viewing of key frame relay statistical
information. Other management options described in this chapter
provide configuration and diagnostics capabilities as well as all-
inclusive statistical information.
Local VT-100 Terminal Management
Connect a VT-100 terminal to the TSU IQ+ CONTROL port. This
interface provides full-screen configuration and all-inclusive
statistics access. VT-100 management also allows for remote
configuration. Through this port, a remotely located TSU IQ+ is

fully accessible for configuration, diagnostics, and statistics
viewing. Figure 4-1 shows 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.

Chapter 4. Applications
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
TSU IQ+ can be managed through an established Telnet session or
an SNMP-based network manager like HP OpenView®, IBM
Netview®, or SunNet Manager®.
The ADTRAN TSU IQ+ 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 TSU IQ+'s Control port.
A device (e.g., a router) running async PPP protocol.
Connection is made through the TSU IQ+'s Control port.
A LAN. Connection is made through the optional 10BaseT
Ethernet interface provided on the ethernet card (part number
1204005L1).

In-Band Management
The ADTRAN TSU IQ+ supports three modes of in-band
management using the frame relay structure of PVCs. These
modes are local, shared, and dedicated PVC management. All three
types support complete SNMP management as well as Telnet
capabilities.
All PVC-based in-band management traffic must be noncompressed IP
Local PVC Management
Local PVC management refers to a PVC created between the
TSU IQ+ and the frame relay router on the DTE (V.35) interface of
the TSU IQ+ (see Figure 4-3 on page 4-6). This type of management
is ideal when local management 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 theWAN serial port of the router as
normal WAN traffic and is terminated in the TSU IQ+. Since the
TSU IQ+ 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 TSU IQ+. Accomplish this by setting a
value (between 16 and 1007) for the DTE management DLCI on the
TSU IQ+ to a value not used by the frame relay network.

Chapter 4. Applications
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 management is
that if the remote router goes down, access to the remote TSU is
lost.

Shared PVC Management
Shared PVC management refers to a PVC that is used for normal
data traffic between locations. The TSU IQ+ monitors this PVC for
packets that contain its IP address (see Figure 4-4 on page 4-8).
When the TSU IQ+ detects a packet containing a destination IP
address that matches the TSU IQ+ 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 TSU IQ+s
without being dependent on services from the remote router. This
usually requires a static route at the host location.
By setting local PVC management and shared PVC management on the
remote TSU IQ+, its IP address can be found through Inverse ARP.
Since the unit is set up for shared PVC management, all management
traffic will be intercepted prior to reaching the remote router.

Dedicated PVC Management
Dedicated PVC management refers to the ability to have a PVC
originated from the network and terminated in the TSU IQ+ (see
Figure 4-5 on page 4-10). This is an ideal configuration for third-
party management. It isolates the customer’s data traffic from
network management traffic, and it also acts as a fire-wall that
restricts management data to the TSU IQ+. Dedicated PVC
management is also ideal when the user wants to guarantee access
to a remote TSU IQ+ regardless of the state of the remote LAN.

Minimum Configuration Requirements
The configuration requirements for dedicated PVC management
are identical to those listed for shared PVC management. See the
previous section, Shared PVC Management on page 4-7, for more
information.
DIAL BACKUP APPLICATION
The TSU IQ+ dial backup (DBU) option cards provide single or
multiple site backup, depending on the DBU card option selected.
The TSU IQ+ can be configured to originate a call based on physical
layer conditions (i.e., port failures) and/ or PVC outages. Once the
criteria are met, the TSU IQ+ establishes a call to the configured
phone number (see Table 4-1 on page 4-13) and the connection is
used to carry traffic for the PVC(s) configured for DBU operation.
In the case of PVC outages (not physical layer port failure), the
TSU IQ+'s two-port design allows the TSU IQ+ receiving the call to
continue to use the T1 frame relay circuit for PVCs that are not
affected by 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.

Chapter 4. Applications
call to one site during an outage and restore connection for PVCs to
that destination. With all DBU cards except for the PRI card, you
can make only one call at a time. The other PVCs to other sites in
this scenario will be inactive. If you have a PRI card you can
originate or answer up to 23 calls.
Information entered into the PVC CONFIGURATION table (see Table
4-2 on page 4-13) 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 TSU IQ+ 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 PHONE NUMBER
field set for a null entry. Enter a space character from the VT-100
terminal to create a null entry for DBU PHONE NUMBER field.
The DBU PHONE NUMBER information is only required for the TSU
IQ+ originating the call.
Dial backup application examples are provided in the following
sections.
The configuration selections given may need modification based on your
network configuration.

to the DSX-1 port. To pass data to another device (such as a router),
map the channel to the NX port. Set all unassigned channels to
IDLE.
NX PORT
Configure the PHYSICAL LAYER and FRAME RELAY options for the
V.35 Nx56/ 64 port. Descriptions of the available selections follow.
Physical Layer Options (PHYS LYR OPTS)
Flow Control
This option determines how the TSU IQ+ responds to congestion
during DBU operation.
None
No flow control is used and the TSU IQ+ drops frames during
severe congestion while in DBU operation.
Hardware
The TSU IQ+ 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
Set the CTS lead to FORCED ON or FOLLOW RTS.
Forced On
The CTS lead is always on and the RTS lead is ignored.

Chapter 6. Data Port Configuration
Frame Relay Options (FR OPTS)
The frame relay protocol is a synchronous protocol used to
concentrate two different devices into a common frame relay link to
the network. The TSU IQ+ accepts frame relay frames from a
router or a FRAD (frame relay access device) and routes to/ from
the network port based on the DLCI address. Use the following
selections to determine timeout intervals and error thresholds, and
to configure PVC management settings.
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. Range is 5 to 30 seconds.
N392 and N393
These parameters define the error threshold for the UNI (user to
network interface) formed by the TSU IQ+ 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
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 DTE PORT
STATISTICS menu (see the section Signaling State on page 10-6). The
status returns to ACTIVE once the threshold is no longer exceeded.
The range is 1 to 10.

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 TSU IQ+ to
carry SNMP and TELNET packets to/ from the TSU IQ+ on the
DTE port.
Guidelines for Configuring Management DLCI
If the attached router or FRAD is used to route SNMP/ TELNET
frames to the TSU IQ+, set the MANAGEMENT DLCI to a unique
value (between 16 and 1007) that identifies the virtual circuit
between the router/ FRAD and the TSU IQ+. The router/ FRAD
must also be configured to route the TSU IQ+ IP address to this
DLCI. The IP ADDRESS and SUBNET MASK for the DTE (V.35) 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 management traffic to the
TSU IQ+. Options are ENABLED and DISABLED.
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 TSU IQ+ is used for dial backup.
Follow 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.
Always Off
If enabled, PVC signaling responses are NOT sent to the router,
regardless of the network signaling state. Enable this option to
simulate a PVC failure when the router is going to use an alternate
path for dial backup.

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
CONFIGURATION 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 TSU IQ+ gathers and
displays the information according to the time selected. An
example of a STATISTICS screen in the VIEW BY INTERVAL format is
shown in Figure 10-2 on page 10-5.
The TSU IQ+ cuts the first gathering session short in order to begin fall-
ing 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. There-
fore, 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. An example of a STATISTICS screen in the
VIEW BY DAY format is shown in Figure 10-3 on page 10-5.
The first day's column (i.e., the column furthest to the right) does not rep-
resent a full day's worth of information (unless the unit or the statistics
information was reset at exactly 12 AM).

ARP
•
For Layer 3 tracking to function, the data must be RFC-1490
encapsulated data or RFC-2427 encapsulated data (RFC-2427
superseded RFC-1490). For an IP packet to be recognized, it must
be carried by an RFC-2427 IP header or an RFC-2427 SNAP header
for bridged ethernet. If the SNAP header is carrying a bridged
ethernet packet, the MAC header is examined for the protocol type.
SNAP headers are also examined for IPX and ARP traffic.
The ARP option actually tracks inverse ARP where addresses are resolved
across the WAN link. SNA traffic is recognized by its RFC-2427 header.
Information is gathered for the two protocol types you choose and
is displayed with P1 representing information for PROTOCOL 1 and
P2 representing information for PROTOCOL 2.
There are four different views of the Layer 3 Statistics:
•
•
•
•
Network Port, View by Interval
Network Port, View by Day
DLCI, View by Interval
DLCI, View by Day
Descriptions of the fields found in these menus follow. Field
descriptions are the same for both protocol selections, so “x”
represents the protocol number.
Px Type (current)

Chapter 10. Statistics
Px Type (listed for each interval)
The protocol type being examined for the given interval is
displayed in this field.
When the PROTOCOL type selection is changed (see Protocols 1 and 2 on
page 9-4) the new selection is not accepted by the TSU IQ+ until the end
of the current timed interval. For example, if the TSU IQ+ is configured
for 5-minute timed intervals, and the PROTOCOL type selection is
changed at 12:25, the change will not be recognized until 12:30. This al-
lows the unit to display an accurate interval history of the PROTOCOL
TYPE field.
When the PROTOCOL type selection is changed, the PROTOCOL TYPE
field (P1 TYPE or P2 TYPE) for the current day total (left-most column
on the VIEW BY INTERVAL screens) displays MIXED, indicating that the
displayed information represents more than one protocol type. Mixed is
also displayed for the day total on the VIEW BY DAY screen once the 24
hour period is complete.
Px Rx Frames
In the Network Port view, this is the number of frames received on
the network port that match the selected protocol type. In the DLCI
view, this is the number of frames received on a particular DLCI
that match the selected protocol type.
Px Rx Bytes
In the Network Port view, this is the number of bytes received on
the network port that match the selected protocol type. In the DLCI
view, this is the number of bytes received on a particular DLCI that
match the selected protocol type.
Px Rx Dist%
The distribution percentages show what portion of the data can be
attributed to the protocols being tracked.
Px Tx Frames
In the Network Port view, this is the number of frames transmitted
on the network port that match the selected protocol type. In the
DLCI view, this is the number of frames transmitted on a particular
DLCI that match the selected protocol type.

Top Talkers
The TOP TALKERS STATISTICS menu provides information
regarding the top five talkers in each direction (Rx and Tx) based
on their source IP addresses. This information is useful in
diagnosing network problems. If a user is experiencing slow
response times, this screen shows whether the problem is the result
of the line not having enough total bandwidth to support the
number of users, or if a small number of users are using excessive
amounts of bandwidth. Lower distribution percentages indicate
that there are too many users for that line. High distribution
percentages indicate that some users may be using an excessive
amount of bandwidth (possibly due to the type of applications they
are using). See Figure 10-6 for an example of a TOP TALKERS
menu.

Appendix D
Glossary
AIS
alarm indication signal. A signal transmitted instead of the normal signal to
maintain continuity of transmission. The AIS indicates to the far end the exist-
ence and direction of the transmission fault on the line.
ANSI
American National Standards Institute. Devices and proposes recommenda-
tions 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 communi-
cations 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.
B8ZS
A method of ensuring the ones density requirements in the data flow (12.5%
must be ones) are met by replacing eight zero bits with a code containing inten-
tional bipolar violations (BPVs).

Appendix D. Glossary
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.
BES
bursty errored second. A second in which between 2 and 319 CVs (code viola-
tions) occurred.
bipolar
The predominant signalling method used for digital transmission services, such
as DDS and T1. In this method, the signal carrying the binary value successively
alternates between positive and negative. Zero and one values are presented by
the signal amplitude at either polarity (no-value spaces are at zero amplitude).
bipolar violation
See BPV.
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)
T1 operates at 1.544 Mbps per second.
BPV
bipolar violation. A violation in the alternate mark inversion line code for which
consecutive 1s are represented by pulses of opposite polarity. Bipolar violations
that are not intentional (B8ZS) are counted as errors. Could also be the presence
of two consecutive 1 bits of the same polarity on the T-carrier line.

Appendix D. Glossary
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.
bursty errored second
See BES.
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 T1 service to the customer site. Carriers can be local tele-
phone 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 mul-
tiplexing 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.
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 con-
gested. When rates exceed the CIR, frames may be discarded.

Appendix D. Glossary
clocking
An oscillator-generated signal that provides a timing reference for a transmis-
sion 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.
code violation
See CV.
control port
The electrical interface between the TSU IQ+ 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 tele-
phones.
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 (T1 or
Switched 56 line) coming in from the phone company to either a multiplexer,
channel bank, or directly to another device producing a digital signal (for exam-
ple: a digital PBX, a PC, or data communications device). A CSU performs cer-
tain line-conditioning and equalization functions and responds to loopback
commands sent from the central office. A CSU regenerates digital signals. It
monitors them for problems, and provides a way of testing the digital circuit.

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 sig-
nal 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
DDS
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.
digital data service. AT&T private line service for transmitting data over a digi-
tal system. The digital transmission system transmits electrical signals directly,
instead of translating the signals into tones of varied frequencies as with tradi-
tional 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 qual-
ity of service within the network. Frames with the DE bit set are considered
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
DTE
data service unit. A device designed to transmit and receive digital data on dig-
ital transmission facilities.
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.
EER
excess error rate. The number of code violations (CVs) are counted to determine
a current error rate. If this rate exceeds a threshold set by the user, the line is said
to be in an excess error rate (EER) condition or state.
encapsulation
A process by which an interface device places an end device's protocol-specific
frames inside a frame relay 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 net-
work sometimes referred to as DTE. As a source device, it sends data to an inter-
face 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.
ESF
extended superframe. A framing format which consists of 192-bit frames
grouped into 24-frame superframes where 12 of the 24 framing bits are used as
an out-of-band communications channel. Of these twelve bits, six are used for
frame synchronization and six are used for a cyclic redundancy check (CRC).
This method greatly increases performance monitoring capability and enables
remote performance monitoring not available in superframe (SF).

of service are defined by network management. Analogous to an X.25 perma-
nent virtual circuit, a PVC consists of the originating frame relay network ele-
ment address, originating data link control identifier, terminating frame relay
network element address, and termination data link control identifier. Originat-
ing refers to the access interface from which the PVC is initiated. Terminating

equipped to provide frame relay support to the LAN devices they serve. A
frame-relay-capable router encapsulates LAN frames into frame relay frames
and feeds those frame relay frames to a frame relay switch for transmission
across the network. A frame-relay-capable router also receives frame relay
frames from the network, strips the frame relay frame off of each frame to pro-
duce the original LAN frame, and passes the LAN frame on to the end device.
Routers connect multiple LAN segments to each other or to a WAN. Routers
route traffic on the Level 3 LAN protocol (e.g., the internet protocol address).
