Glossary
S/T Interface~WSIU
S/T Interface
Reference interface points (“S” or “T”) of an ISDN network. S/T interfaces are
RJ45, 8-wire connection interfaces for ISDN equipment. An NT-1 is needed to network U-
type BRI lines to S/T type interfaces.
TAPI
Telephone Application Programming Interface.
TA
Terminal Adapter or ISDN modem that converts PC and other types of protocol into a signal
that works with ISDN. Generally, TAs support RJ11 voice ports and RS-232C or V.35 or
V.449 data interfaces.
T1/DS-1
See RDTU.
TCIU1
Caller ID—An optional PCB that provides the Caller ID option in the Strata DK424.
TCIU2
Caller ID—An optional PCB that provides the Caller ID option in the Strata DK40.
TCOU
Four-Circuit Loop Start CO Line Board— An optional PCB providing four loop start CO line
circuits in the Strata DK40.
TDDU
Four-Circuit DID Line Digital Telephone Interface Unit— An optional PCB providing four DID
line circuits in the Strata DK40.
TE
Terminal Equipment. This refers to devices using ISDN service (telephones, faxes,
computers, etc.). TE1 supports ISDN formats with S/T or U-type intefaces.
TSPI
Telephony Service Provider Interface.
TSIU
RS-232 Ports—An optional PCB that provides up to two RS-232 interface ports (modular
jacks) enabling the DK40 to connect to various hardware devices.
TTY
Flexible RS-232 port which can be used for maintenance SMDI and MIS (ACD).
U Interface
A single twisted pair of copper wire on an RJ11 jack. The wiring is identical to POTS, with
different signaling. Only one U-interface device can be attached per line.
universal slot
Slots in a telephone KSU/cabinet that are used for a variety of optional PCBs.
WSIU
Serial Interface Board (DK14)—Provides two serial ports for either a Station Message Detail
Recording (SMDR) device or a maintenance terminal or modem, or Caller ID interface.
