PRODUCT OVERVIEW
The ADTRAN IQ Probe provides the visibility and control
needed for both the physical and logical connections made in
frame relay networks. The IQ Probe provides logical layer
monitoring and management for frame relay. Each permanent
virtual circuit (PVC) accessed through an IQ Probe 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. The statistics are viewable through the IQ Probe using
the front panel, the VT 100 interface, or the Frame IQ MIB
(management information base). This information can be
gathered by management systems via SNMP (simple network
management protocol) and used to monitor network health and
perform long-term network planning.
Chapter 1. Introduction
Chapter 1
Introduction
The unit's embedded SNMP agent provides complete SNMP
access to the unit. SNMP access is available through the DTE or
DCE port or through an integral SLIP (serial line internet
protocol) or PPP (point-to-point protocol) async port. The IQ
Probe also provides integrated 10baseT ethernet access for
SNMP.
The following are features of the IQ Probe:
• Complete and comprehensive frame relay monitoring
• Real-time measurement of bandwidth utilization, committed

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 a device such as a router
or FRAD (frame relay access device) and monitored by the IQ
Probe.
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.
2 IQ Probe User Manual 61200214L1-1
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 in-band with support
for RFC 1315 (frame relay DTE MIB), RFC 1213 (MIB II), 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-TCP/IP environments, VT 100 and front panel operation are
supported.
Chapter 1. Introduction
The IQ Probe's embedded SNMP feature allows the unit to be
accessed and controlled by a network manager in-band at the
DTE or DCE interface, out-of-band at the control port via SLIP or
async PPP, or using a LAN connection.
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 or management of the network
devices. It resides on a network management station.
61200214L1-1 IQ Probe User Manual 3
Chapter 1. Introduction
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.
TELNET
TELNET provides a password-protected, remote login facility to
the IQ Probe. TELNET allows a user on a network manager to
control the IQ Probe through the terminal menus.
DIAL BACKUP OPERATION
The IQ Probe dial backup (DBU) option cards allow frame relay
circuit outage recovery for one user-to-network interface (UNI)
at a time. The IQ Probe can be configured to originate a call
based on physical layer conditions and/or PVC signaling loss.
Once the criteria are met, the IQ Probe establishes a call to the
configured phone number and the connection is used to carry
traffic for the PVC(s) configured for DBU operation.
These cards allow the unit receiving the call to continue to use
the network frame relay circuit for PVCs that are not affected by
the outage, while using the DBU interface for PVCs that are
inactive due to the outage. An IQ Probe 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.
The cards are field-installable by the customer. See the chapter
Installation for information on installing DBU cards. The DBU
cards are compatible with other ADTRAN ESP products
supporting DBU. The backup options are described in the
following section, ESP Card Options. Contact the local telco
provider to determine which services are available in your area.
See the chapter Applications for more information, including an
example of a dial backup application.
