Glossary
Alternating current.
A product family and a registered trademark.
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-D, DBM-I, DBM-S, or DBM-V, the primary core
and the active core are the same.
Advanced Diagnostic protocol. An enhanced diagnostic communication protocol used with
the 6700 and 6800 Series NMS and with certain front panel diagnostic functions.
A single bit stream that combines two or more bit streams.
Alarm Indication Signal. A signal transmitted instead of the normal signal to continue
transmission continuity and to indicate to the receiving terminal that a transmission fault
exists at either the transmitting terminal or upstream of the transmitting signal. Sometimes
referred to as Blue Alarm.
An abnormal condition affecting modems, multiplexers, and data services units, usually
requiring attention. Major alarms indicate a service disruption; minor alarms are less severe,
but are indications of a developing problem.
The unused Port 1, either the V.35 or the EIA-232-D interface, provides an aggregate data
path for an external dial backup unit.
A type of signal composed of continuously variable values, used to transmit voice or data
over telephone lines.
ACCUNET Spectrum of Digital Services. 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.
This feature allows a device to be controlled from an async (asynchronous) terminal like an
ASCII terminal. When enabled, the async terminal menus emulate the front panel without
being limited by the 2-line, 16 character LCD, which can accommodate only three selections
per screen.
A group of commands, issued from an asynchronous DTE, that allow control of the modem
while in Command mode. All commands must begin with the characters AT and end with a
carriage return.
