Abstract:
A method of verifying connections for channels of network data along transport paths within a delivery unit that provides an interface between telecommunications media and a switching matrix, comprising the steps of:assigning a unique path verification code to each of said channels; formatting said channels for transport within said delivery unit in subframes, each subframe containing one or more of said channels, and such that each channel has an associated path verification bit, and such that for each said channel, said associated path verification bit is selected and sequenced such that said path verification code and a frame pattern are transported in a path verification superframe formed by accumulating path verification bits over a number of said subframes; transporting said subframes within said delivery unit; at the end of a transport path, for each said channel, comparing said path verification code transported during said transporting step with an expected path verification code; and registering a path verification error if said comparing stepresults in a mismatch.
