Abstract
A method of verifying transport within a delivery unit that interfaces telecommunications media to a switching matrix. Each channel of network data has an associated path verification code. The channels are transported within the delivery unit in subframes. For each channel, the path verification codes as well as a framing pattern are transported by accumulating path verification bits over a superframe. Path verification monitoring is performed regardless of channel position in the subframe and regardless of whether channels are in phase with each other.
