Description
The Telica 89-0367-A-4 is a multi-port DS-1 interface card designed for use in Telica Plexus 9000 series telecommunications systems. This module provides multiple DS-1 (T1 or E1) electrical interfaces on a single board, allowing the system to terminate and process several digital trunks simultaneously.
It is used to aggregate channelized voice or data traffic from multiple DS-1 lines and pass it into the Plexus system backplane for switching or transport. The A-4 suffix identifies a specific hardware revision of the 89-0367 module, typically related to component updates or compatibility improvements.
