Introduction
PRODUCT OVERVIEW
The ADTRAN TSU IQ Rackmount provides the visibility
and control needed for both the physical and logical connections made in frame relay networks. The TSU IQ Rackmount provides logical layer m onitoring and
management for frame relay. Each permanent virtual circuit (PVC) accessed through a TSU IQ Rackmount is managed end-to-end as if it were a leased-line connection.
Real-timestatistics on throughput,bandwidth utilization,
availability, bursting, congestion, and network delay are
collected and stored in the Frame IQ MIB (management
informationbase). This information can then be gathered
by management systems and used to monitor network
health and perform long-term network planning.
The unit's embedded SNMP (simple network management protocol) agent provides complete SNMP access to
theunit.SNMPaccessisavailablethroughtheDTEor
network port or through an integral SLIP (serial line internet protocol) or PPP (point-to-point protocol)async port.
10BaseT ethernet access is also provided for SNMP.

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. Virt ual circuits are addressed using
header information at the beginning of each frame. These
frames are formatted by the Enterprise Networking users
(END) such as the ADTRAN TSU IQ Rackmount.
ANSI (American National Standards Institute) standards
describe how each frame must be constructed to provide
interoperability between END 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.
Chapter 1. Introduction
Frame relay virtual circuits may be definedas permanent
(PVC) or switched (SVC). PVCs have the same DLCI for a
givenpatheachtimeauserprotocolsessionisestablished. 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 END 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 demandforT1datacommunication,whichnowisalarge
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
1.544Mbps and is usually extended by repeaters 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 framingknown 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.
1-4 TSU IQ Rackmount User Manual 61200277L1-1
Fractional T1
FractionalT1 (FT1) letsthe buyer purchaseless 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.
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-ofpresence (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.
Fornon-SNMPenvironments,VT-100 andfrontpanel operation are supported.
Chapter 1. Introduction
The TSU IQ Rackmount'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-ofband at the control port via SLIP or async PPP, or using a
LAN connection.
The term SNMP 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 databases. 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.
61200277L1-1 TSU IQ Rackmount User Manual 1-5
Chapter 1. Introduction
TELNET
Agent
Control program that resides in each connected network
device. This programresponds 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 provides a password-protected, remote login facility to the TSU IQ Rackmount. TELNET allowsa useron a
network manager to control the TSU IQ Rackmount
through the terminal menus.
DIAL BACKUP OPERATION
The TSU IQ Rackmount dial backup (DBU) option cards
providesingleormultiplesitebackupdependingonthe
DBU card option selected. The TSU IQ Rackmount 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 Rackmount establishes a call
to the configured phone number and the connection is
used to carry traffic for the PVC(s) configured for DBU
operation.

inactive due to the outage. A TSU IQ RM 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.

Applications
Thischapterprovidesexamplesof somecommon TSU IQ
Rackmount 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 man agement DLCI must be RFC 1490
encapsulated IP traffic.
MANAGEMENT APPLICATIONS
One of the main advantages of t he TSU IQ Rackmount is
management flexibility. The management options described in this ch apter provide configuration and diagnostics capabilities as well as all-inclusive statistics
information.
Local VT-100 Terminal Management
Connect a VT-100 terminal to the TSU IQ Rackmount
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 Rackmount 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.

In-Band Management
The ADTRAN TSU IQ Rackmount supports three modes
of in-band management using the frame-relay structure
of PVCs. These modes are local, shared,anddedicated PVC
management and are described in the following sections.
All three types support complete SNMP management as
well as TELNET capabilities.

All PVC-based in-band management traffic must be noncompressed IP
and use RFC 1490 encapsulation.
61200277L1-1 TSU IQ Rackmount User Manual 4-5
Chapter 4. Applications
Local PVC Management
Local PVC management refers to a PVC created between
the TSU IQ Rackmount and the frame relay router on the
DTE interface of the TSU IQ Rackmount (see Figure 4-3).
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 the WAN serial port of the
router as normal WAN traffic and is terminated in the
TSU IQ Rackmount. Since the TSU IQ Rackmount responds to Inverse ARP, it is notnecessary to set up a static
routein the router.The router willdiscover the IP address
automatically; however, it will be necessary to set up a local PVC between the router and the TSU IQ Rackmount.
This is done by setting a value (between 16 and 1007) for
the DTE management DLCI on the TSU IQ Rackmount 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.
When using local PVC management, 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 (see Figure 4-4). The
TSU IQ Rackmount monitors this PVC for packets that
contain its IP address. When the TSU IQ Rackmount detects a packet containing a destination IP address that
matches the TSU IQ Rackmount IP address, the unit interceptsthe packet and processesits 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 Rackmounts without being dependent on services
from the remote router. This usually requires a static
route at the host location.
ONFIGURATION>SYSTEM>TRAPMGROPTIONS
.
By setting local PVC management and shared PVC management on the
remote TSU IQ Rackmount, 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.

DIAL BACKUP APPLICATION
The TSU IQ Rackmount dial backup (DBU) option cards
provide single or multiple site backup, depending on the
DBU card option selected. The TSU IQ Rackmount 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 Rackmount establishes a
call to the configured phone number (see Table 4-1 on
page 4-14) and the connection is used to carry traffic for
the PVC(s) configured for DBU operation.
InthecaseofPVCoutages(notphysicallayerport
failure), the TSU IQ Rackmount's two-port design allows
the TSU IQ Rackmount receiving the call to continue to
usetheT1framerelaycircuitforPVCsthatarenot
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.
A TSU IQ Rackmount 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. 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 4-14) 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 Rackmount
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 P
HONENUMBER
field set
for a null entry. Enter a space character from the VT-100
terminal to create a null entry for DBU P

field.
The DBU phone number information is only required for
the TSU IQ Rackmount originating the call.
Examples of dial backup for non-PRI and PRI, are shown
in the following sections.

DBU Application 1 (non-PRI)
The following application shows the critical configuration required for a case where all end points of the frame
circuit are equipped with single call DBU units (see Figure 4-6). This setup allows any remote site to place a call
to the host site or the host site to place a call to each remote site based on PVC failure. This setup also allows the
host to design primary and alternate sites to call based on
port failure criteria using the call order parameter.

Chapter 6. DTE Port Configuration
Hardware
The TSU IQ Rackmount 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.

TC Clock Option
Normal
Clock for DTEs transmit data normal phase.
Inverted
Clock for DTEs transmit data inverted phase. This setting 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's DTE port.
Frame Relay Options
The frame relay protocol is a synchronous protocol used
to concentrate two different devices into a common frame
relay link to the network. TheTSU IQ Rackmount accepts
frame relay frames from a router or a FRAD (frame relay
accessdevice) and routes to/from the network port based
on the DLCI address.
T391
Set the time-out (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 TSU IQ Rackmount DTE port and the attached frame relay device. If
the errorthreshold is met, the signaling state status is
OWN
changed to D
, 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.

To use local PVC management, enter the management
DLCI. The management DLCI is a special DLCI used between the a ttach ed DTE device and the TSU IQ Rackmount to carry SNMP and TELNET packets to and from
the TSU IQ Rackmount 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 Rackmount, set the M
AGEMENT
DLCI to a unique value (between 16 and 1007)
AN
that identifies the virtual circuit between the router/
FRAD and the TSU IQ Rackmount. The router/FRAD
must also be configured to route the TSU IQ Rackmount

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 begin. 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).

YSTEM
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 Rackmount gathers and displays the information according to the time selected.
The TSU IQ Rackmount 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 lastreset 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.
This view provides historical information for the last seven days (notincludingthe 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).
