A switching matrix interface for a delivery unit that transports network data on telecommunications media to a switching matrix. The interface shares a &ldquo;common building block&rdquo; format with other modules of the delivery unit. Specifically, a bus interface port of the interface transports network data from the delivery unit (prior to switching) and back to the delivery unit (after switching) in a common data format. Buffers provide timing and align for transport to and from the switching matrix. The interface provides a path verification scheme using a superframe format for path integrity bits.

OC-3 delivery unit; switching matrix interface

A delivery unit for interfacing telecommunications media to a switching matrix. The delivery unit functions are partitioned into a number of application modules. Each application module has a controller that handles control messages. Each controller is built from the same circuitry and operates in the same manner so as to provide a common software platform for originating and terminating control messages within the delivery unit.
