F9 - Mdm; F10-Rs232C; Establishing A Modem Connection - Comdial DX-80 Technical Manual

Maintenance and Trouble Shooting

3.5.4.10 F9 - Mdm

Remote connection to the DX-80 system is possible via modem. The optional modem may be pur-
chased allowing remote administration of the DX-80 system database and maintenance operations.
The default directory number of the modem is 199. Some working knowledge of modem operation
and connection is useful.

3.5.4.11 F10-RS232C

This function key is used to setup the PC COM port. To successfully setup the PC COM port you must
know how the PC hardware is configured. In this utility you must select the COM Port number (PC-
DBA supports COM 1 or 2 only) and the baud rate that will be used for the connection. At default PC-
DBA is setup to use COM Port 1 at 9600 bps. (9600 bps matches the default baud rate set for the DX-
80 CPM – PC-DBA Port.)
While using a modem connection, it is best to set the COM port baud rate at 2400 bps since this is the
speed of the DX-80 optional modem; setting this speed can expedite the modem negotiation process
since compression link choices will not be attempted.

3.5.5 ESTABLISHING A MODEM CONNECTION

If the system is not equipped with an automated attendant or a voice mail in auto attendant mode, make
sure the attendant is aware that a modem connection will be taking place. Use of the automated
attendant can greatly assist the modem connection process since you can enter the modem extension
remotely.
