Government Requirements and Equipment Return

Certain governments require that instructions pertaining to CSU connection to the
telephone network be included in the installation and operation manual. Specific
instructions are listed in the following sections.
Notice to Users of the United States Telephone Network
1. This equipment complies with Part 68 of the FCC rules. On the equipment is a label
that contains, among other information, the FCC registration number and ringer
equivalence number (REN) for this equipment. The label is located on the bottom
of the 3150 CSU. If requested, this information must be provided to the telephone
company.
2. There are two types of telephone lines associated with the standalone equipment.
The T1 network connection should be made using a Universal Service Order Code
(USOC) type RJ48C jack. The Service Order Code 6.0F should be specified to the
telephone company when ordering the T1 line. In addition, the proper Facility
Interface Code must be specified to the Telephone Company. The CSU can be
configured to support any of the following framing format and line signaling
techniques. The CSU's configuration must correspond to the T1 line's parameters.
The 3150 CSU's internal modem connects to the Public Switched Telephone
Network using a USOC Type RJ11C jack. The Facility Interface Code 02LS2 along
with the RJ11C jack should be specified to the telephone company when ordering
a dial line for the modem.

3. The ringer equivalence number (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.
