Modems
There are several ways to use modems with your system, as described below.
NOTE:
Modems can connect directly to an extension jack without an adapter. 
However, if you connect a high-speed modem through the control unit, you 
may experience some degradation of efficiency and throughput, depending 
on the quality of the central office lines connected to the system. To solve 
the problem, either connect modems directly to the network interface jacks, 
or contact your local telephone company for information about upgrading 
line quality.
