ADTRAN’s industry-leading and award­winning DSU/CSU family continues to
provide more flexibility with the TSU IQ.

The TSU IQ provides the visibility and control
you need for both the physical and logical
connections made in Frame Relay networks.
This intelligent solution for managed Frame
Relay access allows you to enjoy the monetary
savings of Frame Relay without giving up
management visibility and control.

Real-time measurements of Frame Relay
metrics are stored in the TSU IQ. 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 TSU IQ
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 software suite. Modular in
design, N-Form combines the features of a
complete SNMP management platform, with
a network trend analysis tool, in an easy-to­use, web-based, low cost package.

The TSU IQ 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 VT100 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
services. The TSU IQ 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 TSU IQ 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
TSU IQ the obvious choice for Frame Relay
monitoring. The IQ series also includes the
IQ Probe, DSU IQ™, TSU IQ+™, and the
NxIQ module for the TSU multiplexer family.
