Glossary, Acronyms, and Abbreviations - IIUSA

DSL - dynamic simulation language
DSL - Digital Subscriber Line. Typically refers to an ISDN line or a T-
1 line, although the term is also frequently used to mean the next
generation beyond ISDN. Sometimes xDSL is used to indicate
that the writer is referring to any of a number of emerging DSL
technologies.

DSTR - destroy
DSU - (Data Service Unit) - Equipment at the customer's site that
connects to a terminal or computer via an RS-232C or V.35
interface. It receives the digital signals from the interface and
converts them to bipolar, balanced signals, and provides loopback
capabilities for network maintenance (DSU loopback). The DSU
and CSU are usually combined in one unit. Also see CSU.

DTE - (Data Terminal Equipment) - In a communications link,
equipment where a communication path begins or ends. In an
RS-232C connection, the user device is regarded as DTE, and
the modem as DCE (Data Communication Equipment). When
using serial communications such RS-232, V.35, or X.21, the DTE
is the device sending/receiving from a modem or CSU/DSU. In
contrast to DCE.

DTIC - Defense Technical Information Center
DTLS - descriptive top level specification
DTM - data transfer module
DTM - Display Traffic Metering
DTMF - Dual Tone Multi Frequency. The standard tone-pairs used
on telephone terminals for dialing using in-band signaling. The
standards define 16 tone-pairs (0-9, #, * and A-F) although most
terminals support only 12 of them (0-9, * and #). These are also
sometimes referred to as "Touch Tones" (actually a copyrighted
trade name held by AT&T). Note that while digital data terminals
have the same symbols, ISDN uses "common channel signaling"
(over the D channel) and therefore does not necessarily generate
