Telephone Company Compliance—U.S.A. Models

The Telenetics 326X Series Modem complies with Part 68 of the FCC rules. The modem card includes a label with the FCC registration number for this equipment. If requested by the telephone company, you must provide this information. Generally, the ringer equivalence number (REN) is also requested for telephone equipment. The REN is listed on the FCC registration label.

The REN is used to determine the number of devices that can be connected to the telephone line. Excessive RENs on the telephone line may result in the devices not ringing in response to an incoming call. The sum of the RENs should not exceed five. To be certain of the number of devices that can be connected to the line, contact the telephone company to determine the maximum REN for the calling area.

NOTE: The telephone company may make changes in its facilities, equipment, operations, or procedures that could affect equipment operation. If this happens, the telephone company will notify you in advance so that you can make the necessary modifications to maintain uninterrupted service.

This equipment uses the following USOC jacks: RJ11C, RJ16C, RJ45S, RJ4MB, and for the leased line, JM8.

Refer to the 326X Series Modem User’s Guide, Appendix C, Country-Specific

Information, for regulatory agency information for your country.
