Abstract

Methods, apparatus and systems for signaling information between an optical cross-connect switch and attached network equipment such as Internet Protocol (IP) routers, WDM terminals, SONET add/drop multiplexers and ATM switches. In one embodiment, an out-of-band signaling interface between an optical cross-connect switch and attached network equipment is realized by using an out-of-band communication channel over a network. In another embodiment, a decentralized signaling interface is provided by one or more dedicated signal lines between an optical cross-connect switch and attached network equipment.

Claims

AMENDED CLAIMS
[received by the International Bureau on 07 January 2002 (07.01.02), original claims 1 1 -49 cancelled, remaining claims unchanged (1 page)]
the network equipment has one or more optical-electrical -optical converters each providing an electrical signal responsive to optical signals re.ce_.ved from the optical cross- connect switch.
9. The signaling interface of claim 8 wherein, the signals transmitted from the network equipment to the optical cross-connect switch is responsive to electrical signals converted from optical signals received from the optical cross- connect switch by the one or more optical- electrical-optical converters.
10. The signaling interface of claim 1 wherein, the optical cross-connect switch further includes a network management controller to couple to the network to transmit and to receive signals regarding the optical cross-connect switch and network equipment over the signaling channel .
