The Cisco Timing, Communications, and Control Version Two Plus card provides a next-generation system processor for the Cisco ONS 15454 MSPP. The Cisco TCC2 card performs system initialization, provisioning, alarm reporting, maintenance, diagnostics, IP address detection and resolution, SONET data communications channel (DCC) termination, system DC input-voltage monitoring, and system fault detection. This card resides in slots 7 and 11 of the shelf assembly, providing 1:1 equipment protection.

The Cisco TCC2 and TCC2P cards incorporate a highly stable Stratum 3 internal timing reference to provide system timing based on input received from an external Building Integrated Timing Supply source or from an incoming SONET or SDH optical signal. Synchronous status messaging helps the system to select the best timing sources, and a holdover mode maintains timing accuracy in the event that preprovisioned synchronization references are not available.

The card provides 60 Gbps of nonblocking, high-order switch capacity, 1152 x 1152 STS-1s or 384 x 384 VC-4s unidirectional ports and 5 Gbps of low-order switch capacity, 2688 x 2688 VT1.5/VC-11, or 2016 x 2016 VT-2/VC-12 unidirectional ports. The XC-VXC card is installed in slots 8 and 10 as identified by the green cross (+) icon at the bottom of the faceplate and below the shelf slot. The platform's eight multiservice card slots (1 to 4 and 14 to 17) receive 2.5 Gbps of capacity and the high-speed card slots (5, 6, 12, 13) receive 10 Gbps of capacity. The timing, communications, and control (TCC) card works with the XC-VXC card to provision, set up circuits, and maintain connections within the system. The XC-VXC card provides in-service upgrade capabilities, given shelf assembly support, from other cross-connect cards, including the XC, XC-VT, XC-10G, XC-VXL-2.5G, and XC-VXL-10G.

The Cisco ONS 15454 60G/5G High-Order/Low-Order XC-VXC Cross-Connect Card expands the low-order bandwidth management capabilities of the Cisco ONS 15454 SONET and SDH multiservice provisioning platforms (MSPPs).
