Glossary

Automated	IS II/III, MERLIN LEGEND MAIL, and Lucent Technologies
Attendant	Attendant application that automatically answers incoming
	calls with a recorded announcement and directs callers to a
	department, an extension, or the system operator.
Automated	See ADDS.
Document Delivery
System
automatic	Process that occurs in private network when all available
immediate cycling	routes for a call specify systems with matching switch
	identifiers. The call is routed from the originating system to
	the destination system and back to the originating system
	in a continuous loop. Switch identifiers labelling systems
	must be unique across a network.
Automatic Line	See ALS.
Selection
Automatic Number	See ANI.
Identification
automatic	See automatic-start tie trunk.
ringdown tie-trunk
Automatic Route	See ARS.
Selection
automatic-start tie	Tie trunk on which incoming calls are routed to an operator
trunk	or other designated destination without a start signal, as
	soon as the trunk is seized; the destination is specified
	during programming. Also called “automatic ringdown” or
	“auto-in” tie trunk.
auxiliary power	Device that provides additional power to the system.
unit

B

B8ZS	(bipolar 8 zero substitution) Line-coding format that
	encodes a string of eight zeros in a unique binary sequence
	to detect bipolar violations.
backup	Procedure for saving a copy of system programming onto a
	floppy disk or memory card. See also restore.
bandwidth	Difference, expressed in hertz, between the highest and
	lowest frequencies in a range that determines channel
	capacity.
barrier code	Password used to limit access to the Remote Access
	feature of the system. In a private network, it is especially
	important that barrier codes be required for all types of
	remote access.
basic carrier	Hardware that holds and connects the processor module,
	power supply module, and up to five other modules in the
	system. See also expansion carrier.
