TSU IQ
Frame Relay T1/FT1 DSU/CSU
|
ADTRAN's industry-leading and award-winning 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, 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 IQ View, a powerful Windows-based network management system. IQ
View combines the features of a complete SNMP management platform and network
trend analysis tool in one easy-to-use, 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 VT 100
connection, front panel, management access through in-band dedicated or shared
PVCs, SLIPP/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.
