7924-A2-GB20-20
Alternate Mark Inversion coding format.
Bipolar Violation. A type of error detected by using a modified bipolar signaling method in
which a control code is inserted. Used with AMI coding format.
Carrier Detect. A signal indicating that energy exists on the transmission circuit.
Associated with Pin 8 on an EIA-232 interface.
Central Office.
Communications port. A computer's serial communications port used to transmit to and
receive data from a DCE. The DCE connects directly to this port.
Customer Premises.
Customer Premises Equipment. Terminating equipment supplied by either the customer or
some other supplier that is connected to the telecommunications network (e.g., DSUs,
terminals, phones, routers, modems).
Cyclic Redundancy Check. A commonly used method of error detection.
Clear to Send. An EIA-lead standard for V.24 circuit CT 106; an output signal
(DCE-to-DTE).
Code Violation. This is equivalent to a BPV. Used with HDB3 coding format.
Data Communications Equipment. The equipment that provides the functions required to
establish, maintain, and end a connection. It also provides the signal conversion required
for communication between the DTE and the network.
Data Set Ready. An EIA-lead standard for V.24 circuit CT 107; an output signal
(DCE-to-DTE).
Data Terminal Equipment. The equipment, such as computers, printers, and routers, that
provide or create data.
Data Terminal Ready. An EIA-lead standard for V.24 circuit CT 108; an input signal
(DTE-to-DCE).
A data signaling rate common outside the United States. A wideband interface operating at
2.048 Mbps defined by CCITT standards G.703 and G.704.
A predetermined set of configuration options for general operation.
Frame Alignment Signal. A loss of signal (LOS) error detection.
Frame Alignment Word. A loss of synchronization error detection.
Federal Communications Commission. Board of Commissioners that regulates all U.S.
interstate, intrastate, and foreign electrical communication systems that originate from the
United States.
Far End Bit Error. Number of errors reported by the remote equipment.
High Density Bipolar 3 coding format.
High-bit-rate Digital Subscriber Loop. Provides high bandwidth, bi-directional transmission
over copper wire for both T1 and E1 services.
