The Timing, Communications, and Control Card Version Two-series card family is a next-generation system processor for the Cisco ONS 15454 Multiservice Provisioning Platform (MSPP). The TCC2-series performs system initialization, provisioning, alarm reporting, maintenance, diagnostics, IP address detection and resolution, synchronous optical network (SONET) and synchronous digital hierarchy (SDH) data communications channel (DCC) termination, system DC input voltage monitoring, and system fault detection. The TCC2-series card resides in slots 7 and 11 of the shelf assembly, providing 1:1 equipment protection. The TCC2P-version card provides additional security enhancements, allowing the user to configure the front-panel and rear/FMEC Ethernet interfaces as regenerators or provision them with individual IP and MAC addresses for segregated craft and DCC access.
