Glossary
	Page GL-7
clock	When digital signals are transmitted over a
synchronization	communications link, the receiving end must be
	synchronized with the transmitting end to receive the digital
	signals without errors using clock synchronization. A
	system synchronizes itself by extracting a timing signal
	from an incoming digital stream. All the digital facilities in a
	network operate from a single common clock, preferably a
	port connected to a digital PSTN facility on a hub system or
	a system that connects two network systems. In this case,
	all digital facilities specify a loop clock source. One system
	in a network may be specified as a local clock source when
	no functioning digital facility in the network is connected to
	the PSTN. All other digital facilities then use this clock and
	specify their clock sources as loop. Primary, secondary,
	and tertiary clock sources are specified to allow backup
	synchronization in the event that the primary source is out
	of service.
CMS	(Call Management System) DOS-based application that
	simulates the actions of a system operator by answering
	and distributing calls. Also produces reports for call
	analysis.
CO	(central office) Location of telephone switching equipment
	that provides local telephone service and access to toll
	facilities for long-distance calling.
coaxial cable	Cable consisting of one conductor, usually a small copper
	tube or wire within and insulated from another conductor of
	larger diameter, usually copper tubing or copper braid.
codec	(coder-decoder) Device used to convert analog signals
	such as speech, music, or television to digital form for
	transmission over a digital medium and back to the original
	analog form.
collected digits	Digits that a caller dials in response to an integrated voice
	response application’s menus (also called prompted digits);
	collected digits may be used to initiate screen pop at a
	system extension. See also CTI link.
combination	A private network arrangement that combines
configuration	characteristics of Virtual Private Network (VPN), a series
	configuration, and a star configuration.
common channel	See CCS.
signaling
communications	Software-controlled processor complex that interprets
system	dialing pulses, tones, and/or keyboard characters and
	makes the proper interconnections both inside and

outside. Consists of a computer, software, a storage device, and carriers with special hardware to perform the actual connections. Provides voice and/or data communications services, including access to public and private networks, for telephones and other equipment. Also referred to in this guide as “system,” short for MERLIN LEGEND Communications System.
