Abstract
Systems and methods are provided for automatically and remotely establishing a diagnostic channel between a network managed master digital service unit (DSU) and a remote fractional T1 or E1 DSU. In the preferred method, the master DSU sends a priming sequence in all of the DS0s/TS0s of the DS0/TS0 bundle intended for the remote DSU which is comprised of a two second break, followed by a relatively low frequency signal which identifies at least the diagnostic channel for the remote DSU. In response, the remote DSU sends a confirmation signal to the master over the identified diagnostic channel, after which the master DSU can send configuration information over the same diagnostic channel.
