Features and Benefits

• Flexible protection options: The PSM is an addition to the extensive array of protection mechanisms on the Cisco ONS 15454 MSTP, which gives customers the flexibility to choose the appropriate level of protection based on cost and their requirements for network resiliency.
• Cost effectiveness: PSM-based protection is one of the most cost-effective means to provide service resiliency in an optical network. The PMS gives customers an affordable entry-level solution.
• Fast switchover performance: The PSM completes the service switchover in less than 50 milliseconds, which helps ensure minimal disruption to data traffic.
• Easy provisioning and management: The PSM fully integrates with the Cisco ONS 15454 MSTP through Cisco Transport Controller.
• Support for amplified networks: The PSM also works with the Cisco ONS 15454 MSTP amplifiers to extend the reach of the network.

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 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.
