Installing the Telephony Modem 2-11
Telephony Modem Installation Guide Release 4 Standard 3.0 Aug 2004
Procedure 2-4
Connecting the Telephony Modem
Follow these steps to make RF, power, data, and telephone connections to the
Telephony Modem. Before proceeding, complete “Mounting the Telephony
Modem” on page 2-8.
Considerations
• Do not connect the same computer to both the Ethernet and USB ports.
• RF and telephone cables must be provided by the installer.
• The RF connectors both at the Telephony Modem and the wall jack need
to be tightened to a torque pressure of 17 to 23 Kg-cm (15 to 20 in-llb.). If
a torque-limiting wrench is not available, tighten the connections by hand
then tighten a further 1/8 to 1/4 turn with a wrench.
• Improperly tightened RF connectors can allow noise into the network,
possibly causing data errors or dropped calls.
