The Telica 89-0364-A-3 is a DS-3 (T3) input/output interface card designed for use in Telica Plexus 9000 series telecommunications systems. This module provides electrical termination and processing for DS-3 digital circuits, enabling high-capacity trunk connections between the Plexus system and external transport networks.
The card supports DS-3 signaling at 44.736 Mb/s, commonly used for aggregated voice or data traffic. It interfaces directly with the system backplane and converts external DS-3 line signals into internal system traffic for switching, multiplexing, or transport. The A-3 suffix identifies a specific hardware revision of the 89-0364 board.
