206 Installation Manual
External Modem Connection
After connecting the Hybrid IP-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.
• The data compression should be disabled.
• Error Correction is not necessary.
Notes
• Use an RS-232C straight cable for connection between the Hybrid IP-PBX and
external modem.
• An AT command (for initialisation, enabling automatic answer, etc.) can only be
programmed by KX-TDA Maintenance Console. "AT&F0E0V1X1S10=30S12=50" is
stored as the default value.
• For more information about the AT command, refer to the external modem's
instructions.
