COM300 Voice Communication Modem

3. Hardware Installation

3.1 Site Installation

NOTE Connection to telephone company-provided COIN service (Central Office ImplemeNted systems) is prohibited. Connection to party line service is subject to state tariffs.

The COM300 is designed to be used on standard device telephone lines. The COM300 connects to the telephone line by means of a USOC RJ11C jack (standard modular telephone jack).

Connect the cable from the telephone RJ11C jack to the modem as shown in Figure 2. If the telephone company has not installed surge protection in the telephone line (no RJ11C jack), one must install surge protection (Model 6362 or 2372-01) and connect the ring and tip terminal blocks as shown in Figure 3.
