Circuitry for mixed-rate optical communication networks

摘要: Circuitry for a node of an optical communication network has mux and/or demux. In one embodiment, the circuitry and demux implemented on single circuit board, where (1) is configured to combine up eight different incoming OC3/OC12-rate electrical signals into outgoing OC48-rate signal conversion two copies OC48 (2) split working (selected from converted signals) signals. The perform automatic provisioning, which may be (a) addition new OC3/OC12 signal; (b) deletion existing (c) rate-upgrading OC3 OC12 or (d) rate-downgrading signal. When adding signal, automatically determines how move OC3/OC 12 within frame in order accommodate communicates with other corresponding provisioned initiate provisioning at node.
