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 un it'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.

• Real-time measurement of bandwidth utilization, committed
information rates (CIRs), and excess burst rates on each PVC
• True non-intrusive, in-band transmission of statistics
• Embedded SNMP and Telnet through the DTE, network, or
SLIP/PPP port (or through the optional ethernet interface)
• Controlport provides SLIP and async PPP access to SNMP or
VT-100 terminal configuration
• DSX-1 port provides short haul T1 interface for operation with
aPBX
• Dial backup (DBU) available with DBU cards; options include
4-wire Switched 56 (SW56), V.34, PRI, and ISDN
• End-to-end network round trip delay measurements for
network optimization
• 10BaseT ethernet port available with ethernet card
• FrameIQMIBisstandardANSIformatcompatiblewith
popular enterprise reporting systems
• Optional IQ View™ s oftware system provides a cost-effective,
easy-to-use GUI (graphical user interface) for performance
management
• Standard DTE (data terminal equipment) interfaces
The 4-wire SW56 DBU card is compatible with AT&T Accunet and
Sprint SW56 type services. The V.34 DBU card allows switched
backup over the public switched telephone network (PSTN). The
ISDN 1 B+D card supports a U-interface to the basic rate ISDN and
is compatible with National ISDN and AT&TDMS. The DSX-1 port
complies with ANSI T1.102.
The PRI DBU card allows the TSU IQ+ to accept or place up to 23
dial backup calls simultaneously.
The TSU IQ+ provides a V.35 electrical and physical DTE interface
to accommodate a variety of applications.

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 premisesequipment
(CPE)suchastheADTRANTSUIQ+.
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 connectio n 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 t wo points. Most carriers offer fractional T1 in in crements
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.
1-4 TSU IQ+ User Manual 61200275L1-1
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 f rom 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 operationare
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

Chapter 1. Introduction
The term SNMP broadly refers to the message protocols used to
exchange informationbetween 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 o r 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
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, while using the DBU interface f or PVCs that
are inactive due to the outage. A TSU IQ+ 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.
TheTSUIQ+'suniqueDBUcardsarefield-installablebythe 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
Ethernet Card
This option card connects to an ethernet LAN, providing
communication of management traffic between the LAN and the
TSU IQ+.
1-6 TSU IQ+ User Manual 61200275L1-1
4-Wire Switched 56 DBU Card
This dial-up 4-wire SW56 card allows you to pay for data
connection only for the time the unit is active. The regional
operating companies provide the 4-wire local loop service to SW56
customers. The 4-wire SW56 DBU card is compatible with AT&T
Accunet and Sprint SW56 type services.
V.34 DBU Card
The V.34 DBU card provides switched backup of the leased line
application. This module allows backup data rates of up to
33.6 kbps over th e public switched telephone network (PSTN).
ISDN DBU Card
TheISDN1B+DcardsupportsaU-interfacetotheBasicRateISDN
and is compatible with NationalISDN and AT&T DMS. 1B+D Basic
Rate ISDN service provides a switched 56/64 kbps circuit.
Chapter 1. Introduction
PRI DBU Card
The PRI DBU 23 B+D (primary rate interface dial backup) card
allows the TSU IQ+ to accept or place up to 23 dial backup calls
simultaneously. This card supports 64Kbps data service. Incoming
calls will be accept ed for 56Kbps or 64Kbps service. Bonding is not
supported. Fractional PRI capability is supported.
DCE C ard
This module is used to connect a TSU IQ+ to an external DBU
device such as an ISDN terminal adapter. The DTR lead is used to
control the dial process in this case.

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 inband 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 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 allinclusive statistical information.
Local VT-100 Terminal Management
Connect a VT-100 terminal to the TSU IQ+
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.

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
Netview
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
• A device (e.g., a router) running async PPP protocol.
• A LAN. Connection is made through the optional 10BaseT

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 m anagement. 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.

Local PVC Management
Local PVC management refers to a PVC created between the
TSU IQ+ and the frame relay router on the DTE (
)interfaceof
V.35
theTSUIQ+(seeFigure4-3onpage4-6). Thistypeofmanagement
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.
61200275L1-1 TSUIQ+ User Manual 4-5
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

packetsthatcontainitsIPaddress(seeFigure4-4onpage4-8).
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 se ttin g 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 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 thirdparty 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.

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.
4-10 TSU IQ+ User Manual 61200275L1-1
Chapter 4. Applications
A TSU IQ+ 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 e ntered into the PVC C
ONFIGURATION
table(seeTable
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
thesamemanneraswhentheframerelaycircuitisoperational. For
PVCs not used for DBU operation, leave the DBU P

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

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 com mon 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
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.
