T1 Asynchronous Transceiver (T1A)

SKU: 0110-0192 Category:

The line powering T1 Asynchronous Transceiver (T1A) plug-in card provides a DSX-1 rate interface and line-powering. The T1A card operates at the T1 rate of 1.544 Mbps with a receiver sensitivity of -36 dB. Use the T1A card in applications that require transport of intact T1 signals from one network location to another.

Material Status

Production

  • One T1 (1.544 Mbps) interface per card
  • Intact T1 transport
  • Customer T1 service capability
  • Line-powering capability
  • Front panel jack access for testing and monitoring
  • Dual memory support for upgrades

Power and Repeaters

The T1A power feed system (60 mA constant current source at -130 Vdc) can power multiple span line repeaters in any of several power feed options. The number of repeaters is a function of the repeater voltage and wire gauge used between repeaters. The external power feed resistance of the T1A card must not exceed a 2000 Ω equivalent resistance for the network.

Alarms, Test and Stastics

The transceiver has selectable alarm thresholds, BER calculation, performance monitoring statistics, and alarm history.

Line Coding and Signaling

Line coding options are AMI or B8ZS. The T1A card does not perform signaling conversion or datalink termination, only clear transport.

Easy Provisioning

The T1A can be easily provisioned from CUI or Tellabs Panorama Element Management System (EMS)

Many Applications

The T1A transports intact T1 sig nals from the customer premises to the Tellabs 1000 MSAP or from one network location to another. The card also features line powering for applications requiring line-powering capabilities.

Faceplate LED Indicators

The T1A has three LED indicators on the faceplate. The green ACTV LED indicates the plug-in card is communicating with a counter part T1A in another Tellabs 1000 terminal. The ACTV LED blinks rapidly (120 flashes per minute) during self-test and provisioning, and slowly (60 flash es per minute) during a loopback test. The red FAIL LED indicates a plug-in card failure or problem communicating with the CPU. The red FAIL LED blinks when there is illegal signaling. The red LOC LED indicates a problem receiving incoming data (LOS or high BER). The green AIS LED is reserved for future use.
