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).

Management Applications
One of the main advantages of the NxIQ is management
flexibility. The TSU front panel interface provides 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.
This chapter provides examples of some common NxIQ
management options. The examples include VT 100
management, out-of-band SNMP/TELNET management, and inband PVC SNMP/TELNET management.
Descriptions and configuration tips for these management 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 inband management, the management DLCI must be RFC 1490 encapsulated IP traffic.
61200.255L1-1 NxIQ User Manual 19
Chapter 4. Management Applications
LOCAL VT 100 TERMINAL MANAGEMENT
Connect a VT 100 terminal to the NxIQ CONTROL port
(or to the control port on the chassis of an “e” series TSU
product). 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 NxIQ is fully accessible for
configuration, diagnostics, and statistics viewing. Fig-
ure 4-1 shows an example of 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.

Minimum Configuration Requirements for
VT 100 Management
The following options are the minimum configuration
requirements for establishing VT 100 management access.
Baud Rate
Set the baud rate to match the VT 100 terminal rate.
This is accessible from the front panel only (select CONTROL PORT from the CONFIG menu).
Control Port Mode
Set the Control Port Mode for TERMINAL. This selection is found in the SYSTEM CONFIGURATION portion of the CONFIG menu.
OUT-OF-BAND MANAGEMENT
This management option (shown in Figure 4-2 on
page 22) is commonly used in situations where the customer is trying to reduce the amount of management
traffic flowing through the frame relay device. The
NxIQ can be managed though an established TELNET
session or an SNMP-based network manager like HP
OpenView®, IBM Netview®, or SunNet Manager®.
The ADTRAN NxIQ 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 NxIQ's control
port (or the chassis control port on an “e” series
TSU product).
• A device (e.g., a router) running async PPP protocol
(or the chassis control port on an “e” series TSU
product).

INBAND MANAGEMENT
The ADTRAN NxIQ supports three modes of inband
management using the frame relay structure of PVCs.
These modes are local (see Figure 4-3 on page 24), shared
(see Figure 4-4 on page 26), and dedicated PVC manage-
ment (see Figure 4-5 on page 28). All three types support
complete SNMP management as well as TELNET capabilities.
Chapter 4. Management Applications
All PVC-based inband management traffic must be noncompressed IP and use RFC 1490 encapsulation.
Local PVC Management
Local PVC management refers to a PVC created between the NxIQ and the frame relay router on the DTE
interface of the NxIQ. 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
NxIQ. Since the NxIQ responds to Inverse ARP, it is
61200.255L1-1 NxIQ User Manual 23
Chapter 4. Management Applications
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 NxIQ. Accomplish this by setting a
value (between 16 and 1007) for the DTE management
DLCI on the NxIQ 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 management is that if the remote router goes down, then 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 NxIQ
monitors this PVC for packets that contain its IP address. When the NxIQ detects a packet containing a
destination IP address that matches the NxIQ 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.
61200.255L1-1 NxIQ User Manual 25
Chapter 4. Management Applications
Shared PVC management is used to manage remote
NxIQs 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 a shared PVC management on the remote NxIQ, 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 NxIQ. 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 firewall that restricts management data to the TSU.
Dedicated PVC management is also ideal when the user
wants to guarantee access to a remote TSU regardless of
the state of the remote LAN.

N392 defines the number of errors required in a given
event window, while N393 defines the number of polling events in each window.
These parameters define the error threshold for the
UNI (user to network interface) formed by the NxIQ
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.
61200.255L1-1 NxIQ User Manual 35
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 returns to active once the threshold is no longer exceeded.
Management DLCI (MNG DLCI)
To use local PVC management, enter the management
data link connection identifier. The management DLCI
is a special DLCI used between the attached DTE device
and the NxIQ to carry SNMP and TELNET packets to/
from the NxIQ on the DTE port.
Guidelines for Configuring Management DLCI
If the attached router or FRAD is used to route SNMP/
TELNET frames to the NxIQ, set the Management DLCI
to a unique value (between 16 and 1007) that identifies
the virtual circuit between the router/FRAD and the
NxIQ. The router/FRAD must also be configured to
route the NxIQ IP address to this DLCI. The IP address
and subnet mask for the DTE port must also be set in
the System Configuration menu.

Port from the Configuration menu. Full menu trees for
the Network Configuration selections are shown in Figure 5-2 ,Terminal Configuration Menu Tree, on page 31
and Figure 5-3, Front Panel Configuration Menu Tree, on
page 32 in this manual.
The network port terminates the user end of the framerelay UNI interface. The NxIQ 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 network 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 on page 38 appears when Network Port is selected.
In this chapter, the terminal selections are listed first, followed
by the Front Panel selections in parenthesis (if the names differ).

signaling type as the attached frame relay DTE. If
AUTO is selected and there is no DTE device attached,
the NxIQ uses ANSI T1.617-D signaling type.

N392 and N393
N392 defines the number of errors required in a given
event window, while N393 defines the number of polling events in each window.
These parameters define the error threshold for the
UNI formed by the NxIQ network port and the framerelay 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.
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 Network Port Signaling State. The status returns to active, 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 NxIQ (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.

PVC Count
Sets the maximum number of PVCs that the NxIQ 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. History intervals are displayed in the View Option Menu by Interval portions of the Statistics menus.
These views provide data which is divided into columns and 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.

Terminal Statistics Display Options
DTE port, network 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 userconfigured 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).
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
NxIQ gathers and displays the information according
to the time selected.
The NxIQ cuts short the first gathering session 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 only last 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 farthest 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 NxIQ periodically
sends test frames to the remote NxIQ which are then returned for analysis. The bandwidth required is approximately 1 Kbps for each PVC in test. See Figure 10-3 for
the terminal menu.
