when your telephone number is called. In most, but not all areas,
the sum of the RENs of all devices connected to one line should not
exceed five (5.0). To be certain of the number of devices you may
connect to your line, as determined by the REN, you should contact
your local telephone company to determine the maximum REN for
your calling area.

An FCC-compliant telephone cord and modular plug are provided
with this equipment. This equipment is designed to be connected
to the telephone network or premises wiring using a compatible
modular jack that complies with Part 68 rules. See the installation
instructions for details.
Telephone line problems
If your telephone doesn’t work, there may be a problem with your
telephone line. Disconnect the modem to see if the problem goes
away. If it doesn’t, report the problem either to your local
telephone company or to your company’s telecommunications
people.
