Glossary

A configuration area containing configuration options currently in use by the modem.
Anytime a power cycle occurs or a reset is performed or a save is issued using the DCP,
this area is updated with the contents of Active (Saved).
A nonvolatile configuration area containing the most recently saved configuration
options.
Advanced Diagnostic protocol. An enhanced diagnostic communication protocol used
with the 6800 Series NMS and with certain DCP diagnostic functions.
See local analog loop.
A signal, such as a voice, that varies continuously.
The modem is in a state where it is ready to receive an incoming call.
This code (American Standard Code for Information Interchange) is a 7-bit code which
establishes compatibility between data services. ASCII is the standard for data
transmission over telephone lines. The ASCII code consists of 32 control characters
(nondisplayed) and 96 displayed characters. Refer to Appendix E.
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.
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.
A prefix issued before every AT command (except A/ and +++) which identifies the
DTE's data rate, parity, and character length.
The modem automatically determines the asynchronous DTE data rate when using AT
commands.
A capability to respond to a call received over a dial line.
When leased-line operation fails, this function forces the modem to dial the telephone
number stored in directory location 1.
