List of terms

common part convergence sublayer (CPCS)

A sublayer of the AAL-5 layer.

common queuing

An ATM queuing structure in which traffic from two or more connections is placed on a single queue during node congestion. Traffic is processed in round-robin fashion within the common queue. Compare with PHB (page 101).

common transmit clock (CTC) mode

An IMA configuration in which the same transmit clock is used for all physical links in the IMA group. This configuration contrasts with independent transmit clock (ITC) mode.

community of interest (COI)

The source and destination of communications traffic. Two common COIs referred to are as follows:

1A local COI refers to the traffic entering on access ports of a Nortel Multiservice Switch node that is destined for another port on the same node.

2A network COI refers to a matrix of inter-node traffic in the network. For each node in a network, the matrix has an entry for the volume of data originating from that node and terminating on the other nodes in the network.

component

Used by the network operator or administrator to control Nortel Multiservice Switch software, hardware, capabilities, and access services. Each component represents some part of the Multiservice Switch network—a service, a piece of software, or a physical hardware element. Standardized and organized in a highly structured fashion, components provide the model for operator interaction with Multiservice Switch. All commands for provisioning, monitoring, and maintenance are addressed to components.

component administration system (CAS)

The command and control system that processes network management requests by passing them to the appropriate components for action and returns the results to the source of the request. CAS also provisions and creates components on the Nortel Multiservice Switch node. In addition, when working with the network management interface system (NMIS), CAS provides the provisioning view for external network management systems.

component description language (CDL)

A proprietary data modeling language for Passport managed objects. CDL is encoded within FrameMaker .cdf files or ASCII .cdl files.
