Single Line Digital Telephone Features Direct Inward System Access (DISA)
➤
To make an outgoing call with DISA
1. From outside the system, call the
DISA Exchange line telephone
number:___-_____.
See the System Administrator for
this number.
2. Listen for repetitive ringback tone,
then listen for dial tone.
Try again if you hear busy tone.
The dial tone is present for 10 seconds to allow direct
dialling of a station internal number or Exchange line access
code. If a number is not dialled, the system automatically
causes the DISA Exchange line to ring at telephones as a
normal incoming call. Then, if the call is not answered
within 15 seconds after the ringing starts, it disconnects.
3. Dial an Exchange line number or
line group access code. See Table 14
on page 156 .
4. If a DISA security code is required
(see the System Administrator), dial
the code and listen for Exchange
dial tone.
If the correct code is not entered, the call is disconnected.
...or if a DISA security code is not
required, you hear Exchange dial
tone. A timer tone plays (approximately four mins.) that both
parties hear after the call was made.
5. Press
0
to reset the timer four more
minutes; otherwise, the call
disconnects approximately one min.
after the tone.
6. Dial a telephone number.
