Configuring Quadro with ISDN
Fig. 7: ISDN Wizard – Page 3
ISDN L3 Timers:
•
The T302 Timer text field requires the value for the T302 timer in milliseconds
(digit values from 0 to 15000) and indicates the time frame system is waiting for
digit to be dialed and when timer expires, it initiates the call.
•
The T309 Timer text field requires the value for the T309 timer in milliseconds
(digit values from 0 to 90000) responsible for call steadiness during link
disconnection within the period equal to this timer value. If the value in this field is
0, T309 timer will be disabled.
•
The T310 Timer text field requires the value for the T310 timer in milliseconds
(digit values from 1000 to 120000) responsible for the outgoing call steadiness
when CALL PROCEEDING is already received from the destination but call
confirmation (ALERT, CONNECT, DISC or PROGRESS) is not yet arrived.
•
The Alert Guard Timeout requires the value for the Alert Guard Timer in
milliseconds (numeric values from 0 to 500) between CALL PROC and ALERT
messages. Timer it is used when Quadro is connected to a slow ISDN-PBX.
Recommended values are:
- fast connection (0ms);
- normal connection (150ms), default;
- slow connection ISDN-PBX (350ms);
- very slow connection ISDN-PBX (500ms).
