List of terms

control plane protection (CPP)

An IP feature designed to protect the Nortel Multiservice Switch against certain denial of service (DoS) attacks on the control plane. This control plane can be defined as all packets that have locally destined IP addresses within a VR, VCG, RTR, or VRF address space and are terminating on the Multiservice Switch node.

control processor (CP)

A type of processor card optimized to support the software that performs complex, memory-intensive processes. Among other things, these processes parse operator commands, and modify and display provisioning data. The control processor also supports the administration interfaces for the Nortel Multiservice Switch node. Each node must have an active control processor and can also have (for redundancy) a standby control processor. Each control processor contains the disk, a DCE V.24 interface, and an Ethernet interface to manage the node.

control processor (CP) switchover

The process of the standby CP becoming active. This process can occur upon CP failure, restart of the active CP, a manual reset of the CP, or when a switchover is invoked manually using the “Switchover Lp” command.

convergence sublayer (CS)

A sublayer of an ATM adaptation layer.

Coordinated Universal Time (UTC)

A time standard that Nortel Multiservice Switch software uses for establishing network time, that is equivalent to Greenwich Mean Time (GMT). GMT is the time at the Greenwich meridian (0 degrees longitude).

cooling unit

The cooling unit is a hardware component of a Nortel Multiservice Switch node. It contains a forced-air cooling system that ensures adequate cooling of the processor cards. For more information, see NN10600-170 Nortel Multiservice Switch 7400 Hardware Description or NN10600-120 Nortel Multiservice Switch 15000/20000 Hardware Description.

core networking

Encompasses the three Nortel Multiservice Switch networking systems: PORS, and DPRS.

CoS

See class of service (IP CoS) (page 28).

CP

See control processor (CP) switchover (page 35)
