2.5.3 TELEPHONE CONNECTIONS
The RFL 9660 is equipped with a two-wire I/O module. The substation phone will not be disabled once the
RFL 9660 is connected to the telephone line; you will still be able to make outgoing calls.
The RFL 9660's modem will automatically answer after four rings (two rings on "double-ring" telephone
systems). This number of rings is programmable up to 255; consult the factory if you wish to make a change.

standard telephone deskset to the PHONE jack. (See Figure 2-5.) Telephone line cords are not provided with
the RFL 9660. They can be purchased locally, or obtained from your local telephone company.
