Chapter 5: Installing ISDN TA/V Without Using the
Intro
Program
8) Optionally connect a PSTN telephone handset, or any other compatible
analogue equipment, operating in DTMF (tone not pulse) mode to your
ISDN TA/V by connecting the phone’s telephone-line plug into the
socket marked with a handset symbol on the back of the ISDN TA/V.
This port is in effect an analogue to digital converter which allows you to
use your conventional PSTN telephone on an ISDN line.
It is capable of supporting ringing current and call-progress tones, and
will support analogue devices to a maximum of REN=1. Providing one of
the two 64000-bps ISDN channels is not being used by the DTE interface,
it is available for you to make voice calls over the ISDN via this analogue
port.
Incoming ISDN traffic carries a voice/data identifier which enables the
ISDN TA/V to automatically direct incoming voice calls to the handset
port, and incoming data calls to the DTE interface.
9) Plug the unattached end of the supplied line cable into the ISDN wall
socket.
5.2 Powering ON the ISDN TA/V
Having carefully followed the instructions for connecting your ISDN TA/V,
swith on power to the unit by pressing the half of the back-panel
ON/OFF
switch marked with a line. Then switch on power to your computer.
Nine LED indicators on the ISDN TA/V’s front panel are used in conjunction
with the LCD display to report the unit’s current status.
When the ISDN TA/V is initially powered-on it initiates a self-test, which is
shown by the LCD reporting
Self Test
followed shortly afterwards by
Passed
or
Failed
If a self-test failure is reported, or the
POWER
LED fails to light, refer to
Chapter 8, Troubleshooting,
for help.
