Data Link Control Identifier (DLCI)
DMA (Direct Memory Access)
◆
A fast method of moving data
between two subsystems without processor intervention.
DMS/DMS100
◆
The name of a central office switch manufactured by
Northern Telecom. These switches use custom (proprietary) or
National ISDN-1 (NI-1) software.
DSR, Data Set Ready
◆
RS-232 (V.24) interface control signal, sent
from the data communications equipment to the data terminal equip-
ment on pin 6. Indicates that the DCE is connected to the telephone cir-
cuit. Usually a prerequisite to the DTE issuing request-to-send. (See
.)
DSU
◆
CSU/DSU (Channel Service Unit/ Data Service Unit)
.
DTE (Data Terminal Equipment)
◆
Equipment serving as the data
source, the data sink, or both. Refers to terminals, computer ports, and
printers. Also interface signals typically presented by this equipment.
DTR (Data Terminal Ready)
◆
RS-232 (V.24) interface control signal,
sent from the data terminal equipment to the data communications
equipment on pin 20. Indicates the DTE is ready for data transmission
and requesting connection of the DCE to the telephone circuit. (See
.)
EIR
◆
Excess Information Rate
EIS
◆
The SNA Server Emulator Interface Specification.
Encapsulation
◆
Process by which an interface device places an end
device’s protocol-specific frames inside a Frame Relay, X.25, or PPP
frame to a frame relay network must perform encapsulation.
ETS
◆
European Telecommunications Standard from ETSI
ETSI
◆
The European Telecommunications Standards Institute
EuroISDN
◆
The European implementation of Q.931, providing a
common standard for ISDN signalling within Europe. Issued by ETSI
under the ETS 300 series standards. Net3(BRI) and Net5(PRI). See
