connected to one line should not exceed 5. 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.

applicable FCC Part 68 rules and requirements adopted by the ACTA. A compliant telephone cord and modular plug
is provided with this product. It is designed to be connected to a compatible modular jack that is also compliant. See
installation instructions for details.
