An NMS that uses the DATAPHONE II protocol.
The digital network vendor's termination device (modular jack, terminal block, etc).
Network Interface Module. The interface provided, up to two per carrier, for the PSTN.
Network Management System. A computer system used for monitoring and controlling
network devices.
A carrier-mounted circuit card with connectors mounted onto the card. This circuit card type
requires that the DTE cables be disconnected before the circuit card is removed from the
carrier.
A dial modem operating mode characterized by a fixed output power level of –9 dBm.
The diagnostic address of a control DSU or modem derived from its location in the carrier:
its carrier and slot number.
A data network circuit with one control and one tributary device.
Provides low voltage ac power to the COMSPHERE 3000 Series Carrier; internal power
distribution bus.
The circuit card that is normally running when power is supplied to the unit. In the case of a
DBM-D, DBM-I, DBM-S, or DBM-V, the primary core and the active core are the same.
A dial modem operating mode characterized by an output power level (–12 to 0 dBm) set by
a programming resistor in the datajack. It is one of two possible modes of operation for
DSUs or modems connected to dial lines.
The rules for timing, format, error control, and flow control during data transmission.
Public Switched Telephone Network. A network shared among many users who can use
telephones to establish connections between two points.
Used for hardwiring cable circuits of a network interface.
Used with modular devices, a connector plate is installed onto the rear of the COMSPHERE
3000 Series Carrier. It contains two DTE connectors and functions as an interface between
the modular device and the DTE.
Ringer Equivalence Number. Number of wires that can be connected to a telephone line.
A type of 6-position jack normally used with permissive dial networks and telephone sets.
A type of 8-position jack normally used with programmable dial networks.
Return Material Authorization. Provided by customer assistance center for equipment return.
An Electronic Industries Association's standard defining the 25-position interface between
data terminal equipment and data communications equipment.
An EIA standard for a general-purpose, 37-position, DCE/DTE interface.
