<p>The invention provides a module (30) for use in a central service provider interface having access to security system (J4) and voice (J5) and data (J2) communications. The module is wired to allow the security system to seize the telephone line when necessary to indicate a security breached to the service provider by incorporating RJ31 functionality to allow the security panel to seize the primary line if activated. The module (30) is also configured to connect a modem (J2) to an Internet service provider over PSTN twisted pair cable. Primary and secondary telephone lines are passed through the modem via J2 and back via J3 before the telephones (J5) to allow filtering of the data signals.</p> |
