Clear - Channel Bundle - A group of one or more DS0s installed on a<br />
TRK-3 span-mode card. Clear channel bundles provide<br />
connectivity between the Promina or IDNX node <strong>and</strong> off-net PX<br />
platform ports.<br />
CLEC - Competitive Local Exchange Carrier. Your local telephone<br />
service provider who is one of the new-generation providers<br />
rather than a RBOC or Independent. A CLEC is really just an<br />
Independent, albeit one formed after the divestiture of AT&T. See<br />
LEC.<br />
CLEF - commercially licensed evaluation facility<br />
CLF - Comm<strong>and</strong>er L<strong>and</strong>ing Force<br />
CLI - call-level interface<br />
CLI - calling line identification<br />
CLID - Calling Line Identification. This is the ISDN <strong>and</strong> SS7<br />
equivalent of Caller ID; I.E. the number of the calling party. See<br />
also ANI.<br />
clk - clock<br />
CLM - cable length demodulation<br />
CLNP - Connectionless Network Protocol<br />
CLNS - connectionless network service<br />
Clock - An oscillator-generated signal that provides a timing<br />
reference for a transmission link; it controls timing of functions<br />
such as sampling interval, signaling rate, <strong>and</strong> duration of signal<br />
elements. Clocking is accomplished by phase locking to the<br />
appropriate reference derived from ports he or trunks.<br />
Clock - Status - Contains information on where the clock information<br />
is obtained for the node.<br />
CLR - clear<br />
CLS - crosslink subsystem<br />
CLSA - COMSEC logistics support activity<br />
CLSU - communications security logistics support unit<br />
CLTP - connectionless transport protocol<br />
CLTS - connectionless transport service<br />
CLU - comm<strong>and</strong> <strong>and</strong> launch unit<br />
CLUI - comm<strong>and</strong> line user interface<br />
Cluster - Controller - A device that interfaces multiple terminals with<br />
data communications facilities associated with central, major<br />
computer centers. Commonly used in multipoint synchronous<br />
data networks involving distributed transaction processing <strong>and</strong><br />
host-controlled, centralized network architectures, such as SNA.<br />

CMDSA - COMSEC Materiel Direct Support Activity<br />
CMI - computer managed instruction<br />
CMI - (Coded Mark Inversion) - A CCITT line coding technique<br />
specified for the fourth-level CCITT multiplex signal. CMI is also<br />
used in other applications, notably in Japanese DS1 level<br />
systems. CMI is similar to digital biphase coding, in that an<br />
abundance of signal transitions exist, <strong>and</strong> there is no DC energy<br />
in the signal. Additionally there is no limit on the number of<br />
consecutive zeros allowed in the bit stream. CMI encodes ones<br />
(marks) as bipolar NRZ level/AMI; zeros are encoded as a halfcycle<br />
square wave of one particular phase. See waveform coding.<br />
