A device that is, for diagnostic purposes, at the logical head of a hierarchical network. It is
the unit from which tests and commands are issued to other units on the same circuit. There
is only one control per link.
Canadian Standards Association.
Channel Service Unit. Protects the T1 line from damage and regenerates the T1 signal.
Connecting the COM port of one device to the AUX port of another device to provide
connectivity.
The name of both a family of Paradyne NMS products (System Controller, Diagnostic
Console, and Network Controller) and the network management protocol used by these
products.
The ISDN channel that carries signaling information to control call setup.
A 25-pin connector that is used to connect a cable which enables communication between
two devices.
The optional Dial Backup Module for the 3600 Series DSU. This module provides an
alternate data path in case of failure of the digital connection. DBMs available are: V.32
14.4 kbps analog DBM for backup through the PSTN, 2-wire Switched 56 DBM for digital
backup service, 4-wire Switched 56 DBM for digital backup service, and ISDN DBM for
digital backup service with one 64 kbps B-channel for data and voice and one D-channel for
signaling information. The 4-wire Switched 56 DBM is only available for use in the U.S.
A carrier-mounted dial backup unit that provides automatic dial backup and service
restoration of failed digital circuits using 2-wire access over 56 kbps switched digital
services. The primary core is disabled and the unit functions as a DBM instead of a DSU.
A carrier-mounted dial backup unit that provides automatic dial backup and service
restoration of failed digital circuits using an ISDN U-interface with two digital channels.
The primary core is disabled and the unit functions as a DBM, not as a DSU.
A carrier-mounted dial backup unit that provides automatic dial backup and service
restoration of failed digital circuits using 4-wire access over 56 kbps switched digital
services. The primary core is disabled and the unit functions as a DBM, not as a DSU.
A carrier-mounted V.32 dial backup unit that provides automatic dial backup and service
restoration of failed digital circuits over the PSTN. The primary core is disabled and the unit
functions as a DBM, not as a DSU.
A carrier-mounted dial backup unit that provides automatic dial backup and service
restoration of failed digital circuits. Can be DBM-D, DBM-I, DBM-S, or DBM-V. Primary
core is disabled and does not include DSU functionality.
Diagnostic Channel. The diagnostic interface between two network devices, used to extend
the NMS diagnostics to downstream devices.
Data Communications Equipment. The equipment that provides the functions required to
establish, maintain, and end a connection. It also provides the signal conversion required for
communication between the DTE and the network.
