Abstract: PROBLEM TO BE SOLVED: To automatically match the selection of a multiplexing clock with a correspondent node. SOLUTION: The circuit for the node of an optical communication network is configured for multiplexing one or plural input customer signals and demultiplexing an input optical signal and the multiplexing clock and a demultiplexing clock are selected out of one or plural customer clocks recovered from one or plural customer signals, the input clock recovered from the input optical signal and a local clock generated by a local clock generator. This circuit is configured as a drop/continue configuration to select both the multiplexing clock and the demultiplexing clock and when a clock losing state to the multiplexing clock selected before is detected, a hardware based switch is executed to select a backup clock as a new multiplexing clock.

Abstract: PROBLEM TO BE SOLVED: To provide high-speed automatic offline/inline provisioning for easily performing the SONET/SDH point-to-point configuration of maxing and demaxing nodes in a TDM or DWDM network without an error in data entry and transmission. SOLUTION: A circuit for the node of an optical communication network is provided with a multiplexer and demultiplexer which are embodied on a single circuit baseboard. (1): The multiplexer is constituted to connect

Abstract: Circuitry for a node of an optical communication network is configured to mux (i.e., combine) one or more incoming customer signals for transmission as a single outgoing optical signal and to demux (i.e., split) an incoming optical signal into one or more outgoing customer signals, where the muxing and demuxing clocks are selected from one or more customer clocks recovered from the one or more customer signals, an input clock recovered from the incoming optical signal, and a local clock generated by a local clock generator. When configured for an add/drop configuration, the circuitry selects (1) the muxing clock from the one or more customer clocks, the input clock, and the local clock and (2) the demuxing clock from the input clock and the local clock. When configured for a drop/continue configuration, the circuitry is configured to select both the muxing and demuxing clocks from either the first input clock or the local clock. The circuitry is configured to perform a hardware-based switch to select the backup clock as the new muxing clock upon detection of a loss-of-clock condition for the previously selected muxing clock. The node automatically coordinates its selection of muxing clocks with the other corresponding node in order to avoid loop-timing problems.

Abstract: Circuitry for a node of an optical communication network has a mux and/or a demux. In one embodiment, the circuitry has a mux and a demux implemented on a single circuit board, where (1) the mux is configured to combine up to eight different incoming OC3/OC12 - rate electrical signals into a single outgoing OC48-rate electrical signal for conversion in to two copies of an outgoing OC48 optical signal and (2) the demux is configured to split a working incoming OC48- rate electrical signal (selected from two incoming OC48-rate electrical signals converted from two incoming OC48 optical signals) into up to eight different outgoing OC3/OC12- rate electrical signals. The node is configured to perform automatic signal provisioning, which may be (a) the addition of a new OC3/OC12 signal; (b) the deletion of an existing OC3/OC12 signal; (c) the rate- upgrading of an existing OC3 signal to an OC12 signal; or (d) the rate- downgrading of an existing OC12 signal to an OC3 signal. When adding a new OC12 signal or rate-upgradin g an existing OC3 signal, the node automatically determines how to move existing OC3/OC12 signals within the OC48 frame in order to accommodate the new OC12 signal. The node automatical ly communicates with the other node corresponding to the provisioned signal to automatically initiate corresponding signal provisioning at the other node.

Abstract: Circuitry for a node of an optical communication network (102) has a mux (122) and/or a demux (132). In one embodiment, the circuitry has a mux (122) and a demux (132) implemented on a single circuit board, where (I) the mux (122) is configured to combine up to eight different incoming OC3/OC12-rate electrical signals (114) into a single outgoing OC48-rate electrical signal for conversion into two copies of an outgoing OC48 optical signal (106,108) and (II) the demux (132) is configured to split a working incoming OC48-rate electrical signal (selected from two incoming OC48-rate electrical signals converted from two incoming OC48 optical signals (110,112)) into up to eight different outgoing OC3/OC12-rate electrical signals (120). The node is configured to perform automatic signal provisioning, which may be (a) the addition of a new OC3/OC12 signal; (b) the deletion of an existing OC3/OC12 signal; (c) the rate-upgrading of an existing OC3 signal to an OC12 signal; or (d) the rate-downgrading of an existing OC12 signal to an OC3 signal. When adding a new OC12 signal or rate-upgrading an existing OC3 signal, the node automatically determines how to move existing OC3/OC12 signals within the OC48 frame in order to accommodate the new OC12 signal. The node automatically communicates with the other node corresponding to the provisioned signal to automatically initiate corresponding signal provisioning at the other node.
