PRODUCT OVERVIEW
The ADTRAN NxIQ option module installs in the option slot of the TSU muliplexer family of products and
provides a synchronous V.35 interface for frame-relay
applications.
Chapter 1
Introduction
The NxIQ provides the visibility and control needed for
both the physical and logical connections made in
frame-relay networks. The NxIQ provides logical layer
monitoring and management for frame relay. Each permanent virtual circuit (PVC) accessed through an NxIQ
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). This information can
then be gathered by management systems and used to
monitor network health and to perform long-term network planning.
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. When used in the “e” series of TSU products, an
Ethernet interface is available for SNMP access.
61200.255L1-1 NxIQ User Manual

Chapter 1. Introduction
2
The following are features of the NxIQ:
• Complete and comprehensive frame relay monitoring
• Real-time measurement of bandwidth utilization,
committed information rates (CIRs), and excess
burst rates on each PVC
• True non-intrusive, inband transmission of statistics
• Embedded SNMP and TELNET through the DTE,
Network, or SLIP/PPP port (or through the ethernet and SLIP ports on the “e” series TSU products)
• Control port provides SLIP and async PPP access to
SNMP or VT 100 terminal configuration
• End-to-end network round trip delay measurements for network optimization
• Frame IQ MIB is standard ANSI (American National Standards Institute) format compatible with popular enterprise reporting systems
• Optional IQ View™ software system provides a
cost-effective, easy-to-use GUI (graphical user interface) for performance management
• Standard DTE (data terminal equipment) interfaces
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 premise equipment (CPE) such as the ADTRAN NxIQ.
NxIQ User Manual 61200.255L1-1
Chapter 1.
Introduction
ANSI 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.
SNMP Management
SNMP management capability is provided inband 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 NxIQ's embedded SNMP feature allows the unit to
be accessed and controlled by a network manager inband at the DTE or network interface, out-of-band at
the control port via SLIP or async PPP, or using a LAN
connection, available in the “e” series TSU products.

Chapter 1. Introduction
4
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 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.
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.
TELNET
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 NxIQ. TELNET allows a user on a network manager to control the NxIQ through the terminal menus.

Customer Provides
For SNMP management not accessed through the DTE
or network port, the customer must provide access to
the NxIQ either through a SLIP port, Async PPP port
(requires a male 25-pin D-type connector), or a 10baseT
Ethernet port (requires an “e” series TSU product). See
Appendix A: Pinouts for the pin assignments of the con-
trol port (for SLIP and Async PPP).

Attaching the Plug-On Board
Figure 2-2 shows the proper attachment of a plug-on
board to the option module. Perform the following
steps to install the plug-on board:
1. Hold the plug-on board above the option module.
2. Using a downward and right-to-left motion, slip
the V.35 Connector plug into the opening in the
option module back panel.
3. Moving the plug-on board downward, secure the
connection of the header pins at the front of the
boards.
4. Install the two 4-40 screws at both edges of the option module.

Vt 100 Terminal Connection And Operation
To control the NxIQ using a VT 100 terminal, follow this
procedure:
1. Set the NxIQ baud rate to match the terminal
through the front panel (maximum rate is 38.4K).
2. Using the ADTRAN-provided VT 100 terminal
adapter, connect the COM port of a VT 100 compatible terminal or equivalent to the 8-pin modular
jack labeled CONTROL on the rear of the NxIQ.
