Installing a Remote-Access Modem

On systems that do not provide an internal modem in the switch for remote access, you must connect an external modem to serial port 1 for remote dial-up access. On systems that provide an internal modem in the switch, the use of an external modem is not necessary.

To install a remote-access modem, do the following:

1.Place the modem in a convenient place, near enough to the system module, a power source, and access to a phone line.

2.Connect one end of the modem cable to the modem connector labeled RS-232Con the back panel of the modem.

3.Connect the other end of the cable to the communications port on your system module.

4.Using an RJ11 telephone cable, plug one end into the telephone wall jack.

5.Plug the other end of the RJ11 telephone cable into the jack labeled TO LINE on the back panel of the modem.

6.If you plan to use a telephone at this position, using another RJ11 telephone cable, plug one end of the cable into the plug labeled TO PHONE on the back panel of the modem. Plug the other end of the telephone cable into your telephone set.

7.Plug the rounded end of the supplied power cord into the jack labeled POWER on the back panel of the modem.

8.Plug the other end of the power cable into an AC outlet.

9.Refer to the documentation that accompanied your modem for further details.
