Product Overview
The Cisco TCC2 and TCC2P cards (Figure 1) provide a next-generation system processor for the
Cisco ONS 15454 MSPP. The Cisco TCC2 and TCC2P cards perform system initialization,
provisioning, alarm reporting, maintenance, diagnostics, IP address detection and resolution,
SONET and SDH data communications channel (DCC) termination, system DC input-voltage
monitoring, and system fault detection. The cards reside 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.

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 time-of-
day settings after a brownout or complete power outage.
The Cisco TCC2 and TCC2P cards have two 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. This port can also be used for interconnection to
customer operations support systems (OSSs) and network management systems (NMSs),
providing integration to external element management systems (EMSs), NMSs, and OSSs.
