digit conversion
A process used to convert specific dialed numbers into other dialed numbers.
digital
The representation of information by discrete steps. See also
analog
on page 388.
digital communications
protocol (DCP)
A proprietary protocol used to transmit both digitized voice and digitized data over
the same communications link. A DCP link is made up of two 64-kbps information (I-
) channels and one 8-kbps signaling (S-) channel. Digital Communications Protocol.
The DCP protocol supports 2 information-bearing channels, and thus two
telephones/data modules. The I1 channel is the DCP channel assigned on the first
page of the 8411 station form. The I2 channel is the DCP channel assigned on the
analog adjunct page of the 8411 station form or on the data module page.

digital data endpoints
Devices such as the 510D terminal or the 515-type business communications
terminal (BCT).
digital multiplexed
interface (DMI)
An interface that provides connectivity between a communications system and a
host computer or between two communications systems using DS1 24th-channel
signaling. DMI provides 23 64-kbps data channels and 1 common-signaling channel
over a twisted-pair connection. DMI is offered through two capabilities: bit-oriented
signaling (DMI-BOS) and message-oriented signaling (DMI-MOS).
digital signal level 0
(DS0)
A single 64-kbps voice channel. A DS0 is a single 64-kbps channel in a T1 or E1
facility and consists of eight bits in a T1 or E1 frame every 125 microseconds.
digital signal level 1
(DS1)
A single 1.544-Mbps (United States) or 2.048-Mbps (outside the United States)
digital signal carried on a T1 transmission facility. A DS1 converter complex consists
of a pair, one at each end, of DS1 converter circuit packs and the associated T1/E1
facilities.
digital terminal data
module (DTDM)
An integrated or adjunct data module that shares with a digital telephone the same
physical port for connection to a communications system. The function of a DTDM is
similar to that of a PDM and MPDM in that it converts RS-232C signals to DCP
signals.
digital-to-analog
converter (DAC)
A device that converts data in digital form to the corresponding analog signals. See
also
analog-to-digital converter (ADC)
on page 388.
digital transmission
A mode of transmission in which information to be transmitted is first converted to
digital form and then transmitted as a serial stream of pulses.
digital trunk
A circuit that carries digital voice and/or digital data in a telecommunications
channel.
