Glossary

Active (Operating)	A configuration area containing configuration options currently in use by the modem.
	Any time 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).
Active (Saved)	A nonvolatile configuration area containing the most recently saved configuration
	options.
ADp	Advanced Diagnostic protocol. An enhanced diagnostic communication protocol used
	with the 6800 Series NMS and with certain DCP diagnostic functions.
analog loop	See local analog loop.
analog signal	A signal, such as a voice, that varies continuously.
Answer mode	The modem is in a state where it is ready to receive an incoming call.
ASCII	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.
asynchronous	A data transmission that is synchronized by a transmission start bit at the beginning of a
transmission	character (five to eight bits) and one or more stop bits at the end.
AT command set	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.
AT prefix	A prefix issued before every AT command (except A/ and +++) which identifies the
	DTE's data rate, parity, and character length.
autobaud	The modem automatically determines the asynchronous DTE data rate when using AT
	commands.
automatic answer	A capability to respond to a call received over a dial line.
automatic dial backup	When leased-line operation fails, this function forces the modem to dial the telephone
	number stored in directory location 1.
