This is the circuit card function that is normally running when power is supplied to
the unit. In the case of a DBM-V, DBM-S, or DBM-D, the primary core is the only
core.
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
operating modes for a DBM connected to dial lines (see permissive interface).
Public Switched Telephone Network (also called the dial network).
Used when the DSU or DBM operates at a speed greater than the DTE. This
capability is enabled automatically when the port speed is set lower than the line
speed.
A plate that contains two DTE connectors and is used with a modular circuit card.
The rear connector plate allows the removal of a modular circuit card from the front
of the carrier without first disconnecting the DTE cables at the rear of the carrier.
A circuit that accepts data signals from a transmitter.
EIA Request-to-Send lead (V.24 circuit 105).
EIA Received Data lead (V.24 circuit 104).
Application data may be disrupted when running a test, or running the test may
cause the application session to be dropped or terminated. The result depends upon
the protocol, the front-end processor, the time-out parameters, etc.
Diagnostic messages with a duration of .5 seconds or less that are sent over the
primary data channel. These messages may interrupt customer data, causing errors
requiring retransmission of data blocks. They should not, however, cause
termination of the communication session.
A feature that allows carrier-mounted DSUs to share the same control panel.
Installed on one COMSPHERE 3000 Series Carrier, it controls and monitors the
DSUs in all the carriers in the cabinet. A single SDCP can control up to eight
carriers, with a total of 128 DSUs and, if present, 128 DBMs.
A circuit card that plugs into a dedicated slot (slot 0) in the COMSPHERE 3000
Series Carrier to provide the shared diagnostic control panel (SDCP) and network
management interfaces to the DSUs in the carrier. It translates the network
management protocol to the devices in the carrier and routes incoming messages to
the appropriate slots.
The Model 3610 DSU that is designed for desktop operation. A standalone DSU
can be configured as either a control or a tributary.
A service provided by local exchange and interexchange carriers (LECs and IECs)
that allow customers to use high-speed switched digital data capability without
having to subscribe to private network services.
Used in networks containing only 3600 Series DSUs, it is a mode of operation
using control mode idle (CMI) and data mode idle (DMI) signaling in order to
ensure protocol independence of primary data while trapping diagnostic data in the
DSU.
