Spectrum of
Digital Services (ASDS)
An AT&T network service offering the alternatives of fractional T1, 9.6, 56, or
64 kbps (clear channel) digital, and analog access to a digital core network.
active core The core that is transmitting data. For example, the DBM is the active core when
the unit is in Backup mode. In the case of a DBM-V, DBM-S, or DBM-D, the
primary core and the active core are the same (also see core).
Advanced Diagnostic protocol
(ADp) The network management protocol used by the COMSPHERE 6700 and
6800 Series NMSs. It provides diagnostic communication for the network.
ASPEN Asynchronous-to-Synchronous with Prism ENhancements chip. This is a chip
upgrade that includes an async/sync converter to support the Single-Port
Async/Sync feature, which also supports the same functionality as earlier versions
of the 3600 Series DSU.
Async Terminal This feature allows a Model 3610 DSU to be controlled from an asynchronous
(async) terminal. When this feature is enabled, the async terminal menus and
displays emulate the DCP without being limited to the 2-line LCD display.
asynchronous transmission A data transmission that is synchronized by a transmission start bit at the beginning
of a character (five to eight bits) and one or more stop bits at the end.
auto backup A function of the dial backup module (DBM) or carrier-mounted dial backup unit,
whereby the DSU activates the DBM to automatically reestablish a line when a
facility alarm is detected from the DDS network.
auto restoral A function of the DBM where the DSU automatically returns to the DDS network
when service is restored over the private line. On point-to-point circuits, the DSU
test the integrity of the DDS network before switching data back to the private line.
AWG American Wire Gauge.
backbone network The main circuit that carries the data before it is split into extended circuits going to
their final destination.
backplane A common bus at the rear of the COMSPHERE 3000 Series Carrier connecting
each circuit card slot to the shared diagnostic control panel (SDCP) and/or shared
diagnostic unit (SDU). It also distributes low-voltage ac power to each slot.
backup See auto backup.
broadcast A method of transmission. The simultaneous transmission to two or more
communicating devices.
