➤To make an outgoing call with DISA
1.From outside the system, call the DISA Exchange line telephone
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.
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.
...or if a DISA security code is not required, you hear Exchange dial tone.
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.
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.
If the correct code is not entered, the call is disconnected.
A timer tone plays (approximately four mins.) that both parties hear after the call was made.
