Description
The Data Test Set (DTS)
provides a means for a technician at a remote site to implement
a full external loopback at the terminal port of a DSU or modem
and to obtain visual indication of the circuit operation. The DTS
has two physical DB-25 male connectors which support EIA-530, RS-232
(sync and async), and a variant of the V.35 interface standards.
The DTS may be attached directly to the female DB-25 connector on
a DSU or modem, or attached at the end of a cable. Only one connector
on the DTS may be used at one time. The DTS is not intended to be
used with DTE’s such as terminals or PCs
Four light-emitting diode (LED) indicators provide a means for the
technician to view the status of data, clock, and certain control
signals from the DSU or modem. Indicators for clock and data provide
status on the activity of the corresponding signal, while those
four control signals provide status on the signal level. All power
to the DTS is supplied via the DSU or modem from the interface signal
drivers.
The DTD performs a loopback between the following 4 DCE circuits
on both connectors:
| DCE

| Data

(RTS) |
The four indicators
on the DTS monitor the operation of the corresponding circuits
from the DCE. In general, for synchronous DCE all indicators ON
are indicative of a normally operating loopback circuit. For asynchronous
modems, the status of the CLOCK indicator should be ignored.
The DTS has a three year warranty and is housed in a sturdy metal
enclosure.
