List of terms
processor card section
The section of the shelf assembly that contains processor cards and the backplane that allows the processor cards to communicate with each other.
processor control system (PCS)
Nortel Multiservice Switch subsystem responsible for managing the processor cards. PCS detects when a processor becomes available for service, maps the appropriate LP to execute on it, loads its software, and monitors its execution to detect any outage that occurs. If an outage occurs, PCS invokes the appropriate recovery procedures (such as restarting the software or switching over to a spare processor card).
processor module (PM)
The part of some processor cards that handles the processing requirements for a control processor (CP) and a function processor (FP).
product engineering code (PEC)
The product engineering code (PEC) of Nortel Networks hardware identifies the part number of equipment or a set of components that combine to make an assembly or a unit. The PEC is used by hardware installers to verify the correct installation, replacement, or upgrade of equipment.
propagation delay
Is the time it takes one bit of information to travel along a transmission medium from one device (Nortel Multiservice Switch node) to its neighbor device (Multiservice Switch node). Propagation delay is a function of the speed of an electrical (optical) signal and the distance to be travelled.
protected default route (PDR)
A protected default route is a static route to the default route 0.0.0.0, provisioned as ‘protected’, and provisioned with multiple nextHops, each using a unique local IP interface. Because a PDR is protected, the operational states of these nextHops/interfaces are monitored, and the forwarding information for this route is optimally managed to enable route reprogramming within 1 second in the case of an active nextHop/interface failure. A protected default route is only supported for a
