List of terms

customer identifier (CID)

The customer identifier is used in customer network management (CNM) to limit the user’s access to components that belong to the same customer identifier. A CNM operator can send commands only to components provisioned with the same CID as the operator. A CNM operator receives only data collection system (DCS) data, such as alarms, that is generated by components provisioned with the same CID as that of the operator. The special CID of 0 is reserved for the network owner, known as the network manager (Netman). A CID of zero is required to provision the overall network.

customer network management (CNM)

Allows virtual private network (VPN) user access to VPN-specific information, such as real-time alarms and the use and status of VPN network components and shared components.

D-channel

See delta channel (D-channel) (page 41).

D4

One of the framing patterns for DS1, in which there are 12 frames for each multiframe. See also extended superframe (ESF) (page 50).

data circuit-terminating equipment (DCE)

In data communications, the equipment at the network side of a subscriber link that provides both interface control and the means of digital transmission between user premises and the network nodes.

data collection system (DCS)

A software system that collects various types of management data (such as alarms, accounting records, logs, state change notifications, and traps information) and distributes it as requested.

data encryption standard (DES)

A symmetric encryption algorithm standardized by the National Institute of Standards and Technology.

data link connection identifier (DLCI)

Ten bits within the two address octets of a frame relay address header that carry information used to locally identify the virtual circuits or permanent virtual circuits. For more information, see NN10600-900 Nortel Multiservice Switch 7400/15000/20000 Frame Relay Technology Fundamentals.
