Cisco TCC2P Processing Module - For Data Networking 1 RJ-45 10Base-T Network LAN, 1 DB-9 RS-232 Serial - Twisted PairEthernet - 10Base-T 15454-TCC2P-K9-RF

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.
