OC3 delivery unit; unit controller
First Claim
Patent Images
1. A controller for use in a delivery unit that interfaces telecommunications signals to a switching system, comprising:
- a common carrier unit having a bus interface to delivery unit buses, a control interface unit that formats control data transported on said delivery unit buses, a local bus for communications within said common carrier unit, and a bridge from said local bus to an expansion bus;
a processor unit having a processor and associated memory, said processor having a local bus and a bridge to said expansion bus and said processor being programmed to handle administrative and maintenance functions within said delivery unit;
a basic interface unit operable to provide an upper level manager communications link to an upper level manager unit that performs administrative and maintenance functions superior to those of said unit controller;
an expansion interface unit operable to provide a switching system communications link to said switching system;
wherein said processor unit, said common carrier unit, said basic interface unit, and said expansion interface unit are each in communication with said expansion bus.

Abstract
A unit controller for a delivery unit that interfaces telecommunications media to a switching matrix. The unit controller is partitioned into “generic” units, that can be easily configured for use as a line/trunk processor in an OC3 delivery unit. The same unit controller can be adapted for use in other types of delivery units, as well as for higher level controller applications.
