Glossary:
communications system
A software-controlled processor complex that interprets dial pulses, tones, and keyboard characters, and makes the proper
connections within the system and externally. The communications system consists of a digital computer, software,
storage devices, and carriers, with special hardware to perform the connections. A communications system provides
communications services for the telephones on customer premises and the data terminals on customer premises, including
access to public networks and private networks. See also
COM port
A communications port. UNIX recognizes only COM1 and COM2, and presents COM1 and COM2 to the user as TTY
ports. DOS recognizes COM1 and COM2, and also recognizes COM3 an COM4, although there is contention for the
interrupt line when all COM ports are in use.
compression
An audio coding process that reduces 64-Kbps audio streams to sub-16-Kbps rates, at the expense of delay and audio
quality. Compression is useful for transport over the limited-bandwidth dial-up connections that are used with point-to-
point protocol (PPP). Compression is usually referred to as CODEC compression/decompression. Common standard
CODECs are G.723a and G.729. See also
computer telephony integration (CTI)
The combination and interworking of telephony functions and computer operations.
concentration highway
A serial time-division multiplex (TDM) bus that is used to interconnect communications devices.
confirmation tone
A tone that confirms that the system activated, deactivated, or canceled a feature as requested.
connectivity
The state in which a domain of connected devices all adhere to the same set of connection rules. Connectivity is the
property of a network by which dissimilar devices can communicate with each other.

constant bit rate (CBR)
Digital information, such as video and digitized voice, that is represented by a continuous stream of bits. CBR traffic
requires guaranteed throughput rates and service levels.
contiguous slotting
Term that describes adjacent DS0s within one T1 facility or one E1 facility, or adjacent TDM slots or fiber time slots. The
first TDM bus and the last TDM bus, DS0, or fiber time slots are not considered contiguous (no wraparound). For an E1
facility with a D-channel, DS0s 15 and 17 are considered contiguous.
Controlled Local Area Network (CLAN) circuit pack
A circuit pack (TN799B) in a DEFINITY port network (PN) that provides TCP/IP connectivity to adjuncts over Ethernet
or Point-to-Point Protocol (PPP). The CLAN circuit pack serves as the network interface for a DEFINITY server. The
CLAN terminates IP (TCP and UDP), and relays those sockets and connections up to the DEFINITY server.
controlled station
A station that a domain-control association monitors and controls. See also
