T1 Asynchronous Transceiver (T1AX)
The non-line powering T1 Asynchronous Transceiver (T1AX) plug-in card provides a DSX-1 rate interface. It operates at the T1 rate of 1.544 Mbps. Use the T1AX applications that require transport of intact T1 signals from one network location to another.

Features and Benefits

  • One T1 (1.544 Mbps) interface per card
  • Intact T1 transport
  • Customer T1 service capability
  • Front panel jack access for testing and monitoring
  • Dual memory support for upgrades
  • Easy provisioning via CLI or EMS

Included Highlights

Alarms, Test and Stastics

The T1AX 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 T1AX card does not perform signaling conversion or datalink termination, only clear transport.

Easy Provisioning

The T1AX can be easily provisioned from CUI or Tellabs Panorama Element Management System (EMS)

Many Applications

The T1AX transports intact T1 signals 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 T1AX has three LED indicators on the faceplate. The green ACTV LED indicates the plug-in card is communicating with a counter part T1AX 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.
