T1X Transceiver (T1X-XCVR)
The non-line powering T1 Transceiver (T1X-XCVR) plug-in card provides an indoor ANSI/T1 DSX-1 level interface. It transmits and receives up to 24 DS0s of voice or data originating from either the channel units in the CBA subscriber slots, another T1 transceiver card, or a digital carrier line unit in a digital switch. It operates at the T1 rate of 1.544 Mbps. Use the T1X-XCVR card for applications requiring interface to multiplexers or other co-located equipment.
Features
- One T1 (1.544 Mbps) interface per card
- SF and ESF framing formats
- Provisionable line coding
- Front panel jack access for testing and monitoring
- Dual memory support for upgrades
- Easy provisioning via CLI or EMS
Features
Alarms, Test and Stastics
The T1X-XCVR has selectable alarm thresholds, BER calculation, performance monitoring statistics, and alarm history.
Line Coding and Signaling
Line coding options are AMI or B8ZS. The T1X-XCVR card performs signaling conversion and datalink termination.
Easy Provisioning
The T1X-XCVR can be easily provisioned from CUI or Tellabs Panorama Element Management System (EMS)
Cost Savings
The transciever can be provisioned as a cost-saving uplink to an ATM network
