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.

This section applies to countries that use the “Universal International” (UI) Modular 
Nest enclosure backplane. 

This section also is of interest to users in Hong Kong and the United Kingdom.

IMPORTANT: In Hong Kong and the United Kingdom, do not install a 3268 or 
3268FAST Modem (leased line with dial restoral) in a Busy Out backplane. 
The modem will not function.

In Hong Kong and the United Kingdom, Busy Out backplanes are hard-wired for 
Busy Out operation. These backplanes do not use pin jumpers.
