Note
The data listed above applies only to the dialing phase. The data format in the data phase
is set at switch 5 on the MD3 modem.
It is only necessary to set the dialing format on older modems that do not support
"Autoband". With "Autoband", the modem can determine the character and data format in
the dialing phase automatically based on the first AT string.
● Dialing command :
This is the dialing command for the local modem. The following dialing commands are
possible:
– D (AT command)
– DP (AT command, pulse dialing)
– DT (AT command, tone dialing)
– CRN (V.25bis)
– CRNP (V.25bis, pulse dialing)
– CRNT (V.25bis, tone dialing)
Default: D. This default modem dialing command should be used where possible.
●
Dialing prefix :
This is the access number (outside line) for a private branch exchange (typical entry 0 or
9) or for an alternative telephone provider. A number up to 12 digits long can be
specified. With direct connection to the dial-up network and without an alternative
telephone provider, this parameter can remain empty.
The dialing prefix can be changed again in the
Properties of subscriber dialog.
●
Own tel. number :
Here, you enter your own telephone number for the network node including the area
code. This telephone number can no longer be changed later in the
Properties of
subscriber
dialog.
Note
In dial-up networks, in which another subscriber within the same local network cannot be
dialed with the local area code, it is advisable to enter your own telephone number in the
Own tel. number box without area code and to specify the area code in Dialing prefix .
