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 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 statis- tics 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-to- use, 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 dedi- cated 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 phys- ical link and the Frame Relay signal to determine if an interruption has occurred. Once detected, the unit automatically initi- ates 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.
