following sections.
7.5.1 USA
Notice to users of the Public Switched Telephone Network
1. The BRU3 complies with Part 68 of the FCC rules. On the BRU3 is a label
that contains, among other information, the FCC registration number and
Ringer Equivalence Number (REN) for the BRU3. The label is located on
the BRU3 Case top cover, below the handle. If requested, this information
must be provided to the telephone company.
2. The Universal Service Order Codes (USOC) associated with the services
on which the BRU3 is to be connected is RJ21X. The Canadian equivalent
to the USOC is CA21A.
3. The Ringer Equivalence (REN) is used to determine the quantity of
devices which may 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. In most, but not all areas, the sum of the RENs should not
exceed five (5.0). To be certain of the number of devices that may be
connected to the line, as determined by the total RENs, contact the
telephone company to determine the maximum RENs for the calling area.
