Method and apparatus for coupling terminal equipment to a node in an optical communications network
First Claim
1. A method for automatically discovering a cable interconnection between an optical network node and a CSI expansion shelf, comprising:
- coupling an identifying module to each end of a cable connecting a port on the optical network node and a port on the CSI expansion shelf; and
storing a cable identification in each of the identifying modules.

Abstract
An apparatus for automatically discovering a cable interconnection topology in an optical communications network between an optical network node and a CSI expansion shelf employs a memory module attached to each end of a fiber optic cable connecting the node and the shelf. A connector houses a rewritable memory module that stores identification information regarding the type of cable and is capable of storing node and port identification regarding the port to which the end to which the memory module is attached, as well as the node and port identification about the port to which the other end of the cable to which the memory module is attached. The port and node connected information is then broadcast via the control channel to all appropriate entities, such as the master node, or other entity maintaining network topology information. Optionally, a presence indicator causes an interrupt in the port equipment when the cable is initially connected to the port and if and when the cable is disconnected from the port.
