In one embodiment, a method for telecommunications includes steps of receiving a first packet through a first port, and determining whether the first packet arrived over a protected path. If the first packet arrived over a protected path, the method also includes the steps of hashing a source address of the first packet, adding a first entry into a forwarding table, and adding a second entry into the forwarding table. The protected path is coupled to at least the first port and a second port. The first entry includes the result of hashing the packet, and an identification of the first port. The second entry includes the result of hashing the packet, and an identification of the second port.

Method and system for forwarding and switching over protected paths

A system for switching communications signals between a first communications network and a second communications network is provided. The system includes a J1 interface coupled to the first communications network by a J1 span, a E1 interface coupled to the second communications network by an E1 span, and an interface processor in communication with the J1 interface and the E1 interface. The interface processor is then operable to translate signals formatted for the J1 span into an E1 format for transmission on the El span. The interface processor is further operable to translate communications signals formatted for the E1 span into a J1 format for transmission on the J1 span.
