ADTRAN's industry-leading and award-winning DSU/CSU family continues to provide more flexibility with the addition of the ADTRAN TSU IQ+™ (part# 1200275L1 ). The TSU IQ+ is a T1/FT1 frame-aware DSU with an integral DSX-1 interface that terminates voice and data from a mixed mode Frame Relay circuit. This intelligent solution allows a cost-effective approach for customers requiring equipment that supports voice and frame relay data over a single T1/FT1 circuit. Real-time measurements of Frame Relay metrics are stored in the ADTRAN TSU IQ+™ (part# 1200275L1 ). 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 ADTRAN TSU IQ+™ (part# 1200275L1 ) 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 methods of access to the collected performance data. 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 services. 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 ADTRAN TSU IQ+™ (part# 1200275L1 ) 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™, TSU IQ™, DSU IQ™, and the NxIQ module for the TSU multiplexer family. Features of ADTRAN TSU IQ+™ (part# 1200275L1 )
