Supervision time-out (establishment of switched link).

This time-out is activated when the first call packet is on the PSTN line. It is inactivated when the statistics function notices that the line is in service. When the time-out expires, the call is cleared.
Inactivity time-out of the switched connection.
0 to 254 (steps of 1 sec).
This time-out is activated when there are no virtual circuits used on a line. When the time-out expires and there are still no virtual circuits used, the line is taken down. In case a virtual circuit has been opened, the monitoring time continues for 1 second.
Value 0 means that this mechanism is not activated.

The other characteristics of the dialogue are:
Time-out monitoring a dial attempt on the PSTN.
0 to 250 (unit = 10 s).
This time-out is activated at each PSTN dial attempt. It is inactivated when the connection is established or when a modem error message is received. When the time-out expires, a new dial attempt is made after a time-out of three seconds.
The number of dial attempts multiplied by this time-out plus 30 seconds should not exceed the value of parameter 25. If this is the case, the switched link is inactivated when the time-out of parameter 3 expires.
Number of dial attempts.
0 to 250.
Type of input/output
EBA: asynchronous standardized input (DCE defined P1 C12)
SBA: asynchronous standardized output (DTE defined P1 C12).
Remark: It concerns the direction of the call and it serves to establish the physical circuit.

01 = | EBA |
02 = | SBA. |
Number of modem initialization strings (see C20-R0).
0 = | no string |
