Network management information (NMI) contained in a first set of byte locations of a received frame is relocated to a second set of byte locations of another frame. The NMI is then transported through network elements using the second set of byte locations until the NMI is to be transported to a compatible network element, which can understand the NMI. At which time, the NMI is relocated back to the first set of byte locations of frames destined for the compatible network element. The relocation of the NMI from a first set of byte locations to a second set of byte locations allows the NMI to be transparently transported through incompatible network elements.

Method and apparatus for transporting network management information in a telecommunications network

The present invention discloses a method and apparatus for cross-connecting high-speed telecommunications signals at a flexible cross-connect system. A method and apparatus for controlling communications between each of the cards located within the flexible cross-connect system is also disclosed. The method and apparatus also detect and report failures within the system, receive and validate software upgrades from external sources, maintain synchronization within the system, and monitor communication maps for the system.
