ADTRAN’s industry-leading and award-
winning product family continues to provide
more flexibility with the addition of the IQ
Probe.
The IQ Probe is a monitoring device
placed between a router and a DSU/CSU. The
unit provides comprehensive Frame Relay moni-
toring independent of the physical connection
to the network and is derived from the estab-
lished ADTRAN DSU IQ
™
and TSU IQ
™
.
Real-time measurements of Frame Relay
metrics are stored in the IQ Probe. These metrics
include statistics on throughput and utilization
per port and PVC, availability, utilization by
protocol, top talkers, lost frames and PVC state,
excess bursting above CIR, network congestion
(FECN, BECN, and DE), and end-to-end delay
on any or all PVCs. This data is crucial for
pinpointing specific traffic demands and
problem sources in the network, for analyzing
traffic patterns, and for general maintenance
and troubleshooting of the Frame Relay circuit.
The statistics are stored in the IQ Probe in a
standard ASN.1 format making the statistics
available to any SNMP management platform or
trend analysis package. ADTRAN offers N-Form,
a powerful proactive network management soft-
ware suite. Modular in design, N-Form combines
the features of a complete SNMP management
platform, with a network trend analysis tool, in
an easy-to-use, web-based, low cost package.
The IQ Probe supports multiple ways to
access the collected performance data. This
management flexibility accommodates both the
service provider and the end user in any type of
network configuration. Options include simple
VT 100 connection, front panel, management
access through inband dedicated or shared
PVCs, SLIP/PPP or ethernet, and combination
management. Combination management allows
for simultaneous and independent management
by the service provider and the end user.
The IQ family provides automatic dial
backup upon interruption of Frame Relay serv-
ices. The IQ Probe monitors both the physical
link and the Frame Relay signal to determine if
an interruption has occurred. Once detected, the
unit automatically initiates a dial-up call around
the Frame Relay network. A host IQ unit initiates
and accepts calls to and from IQ units at remote
sites. Once connected, the host unit merges
backup traffic with the primary traffic still being
received from unaffected remote sites. The
router or Frame Relay device connected to the
IQ Probe still receives all data as Frame Relay
traffic over the primary connection, allowing a
virtually transparent transition. Once the failed
condition has been cleared and the Frame Relay
interruption is over, the IQ unit automatically
restores traffic to the primary link.
Additional features such as an easy-to-use
front panel interface and modular option
cards combined with the quality, service and
support that ADTRAN is known for makes the
IQ Probe the obvious choice for Frame Relay
monitoring. The IQ series also includes the
DSU IQ, TSU IQ, and the Nx IQ module for the
TSU multiplexer family.
