15454-M-TSCE-K9-RF - Cisco Enhanced Transport Shelf Controller for M2 / M6 / CPT200 / CPT600

The Cisco TNC, TNCE, TSC, and TSCE cards incorporate a highly stable Layer 3 internal timing reference to provide system timing based on input received from an external BITS source or from an incoming SONET or SDH optical signal. Synchronous status messaging helps the system select the best timing sources, and a holdover mode maintains timing accuracy when preprovisioned synchronization references are not available.Nonvolatile database storage for communication, provisioning, and system control is provided, allowing full database recovery and survivability with complete system power loss. In addition, short-term clock recovery is also supported, reducing the need to reset the calendar and ToD settings after a brownout or complete power outage. Unique to the Cisco ONS 15454 M6, ONS 15454 M2, CPT 600, and CPT 200 is a memory module built into the chassis. This external memory is synchronized with the memory of the TNC, TNCE, TSC, and TSCE, thereby providing a backup to the node IP address, software package, and circuit database. This synchronization provides faster time to recovery when the node is used in simplex mode during a control-card replacement.The Cisco TNC, TNCE, TSC, and TSCE cards have 2 built-in interface ports for accessing the system: an RJ-45 connector and an RS-232. The RJ-45 port provides 10BASE-T Ethernet connectivity to the system, providing local and remote access to the craft-management system, Cisco Transport Controller, through a common web interface. You can also use this port for interconnection to customer operations support systems (OSSs) and network management systems (NMSs), providing integration to external element management systems (EMSs), NMSs, and OSSs.
