CAUTION
To protect the system, keep the following in mind:
1.
Make sure that both connector cases (frame ground) of the RS-232C straight cable (shielded cable)
are conductive. If they are not conductive, make sure that both connector cases of the cable are firmly
connected.
2.
If this is not possible, connect the frame of the PBX to the frame of the external modem using an earthing
wire in order to prevent difference in the electrical potentials.
After connecting the PBX and the external modem, set the power switch of the external modem to "ON", then
the external modem will be initialised with the default values.
The following AT command settings may be required for the modem:
•
The Data Terminal Ready (DTR) signal should be ignored.
•
The Data Terminal Equipment (DTE)/Modem flow control should be turned off.
•
Data compression should be disabled.
•
Error Correction is not necessary.
Note
•
An AT command (for initialisation, enabling automatic answer, etc.) can only be programmed by the
Maintenance Console. "AT&F" is stored as the default value.
•
For more information about the AT command, refer to the external modem's instructions.
