Certain governments require that instructions pertaining to CSU and modem connection to the telephone network be

included in the installation and operation manual. Specific instructions are listed in the following sections.

United StatesNOTICE 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 standalone 3160, 3164, or 3165 DSU/CSU, and on the 3161 DSU/CSU’s circuit card.

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 DSU/CSU can be configured to support any of the

following framing format and line signaling techniques. The DSU/CSU’s configuration must correspond to the T1

line’s parameters. The standalone 3160, 3164, or 3165 DSU/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. The 3161

DSU/CSU connects to the T1 network using the multi-line USOC-type RJ48H jack and does not have a PSTN

interface.

04DU9-BN 1.544 Mbps superframe format (SF) without line power

04DU9-DN 1.544 Mbps SF and B8ZS without line power

04DU9-1KN 1.544 Mbps ANSI ESF without line power

04DU-1SN 1.544 Mbps ANSI ESF and B8ZS without line power

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.

4.If the 316x DSU/CSU causes harm to the telephone network, the telephone company will notify you in advance

that temporary discontinuance of service may be required. But if advance notice is not practical, the telephone

company will notify the customer as soon as possible. Also, you will be advised of your right to file a complaint

with the FCC if you believe it is necessary.

5.The telephone company may make changes in its facilities, equipment, operations, or procedures that could affect

the operation of the equipment. If this happens, the telephone company will provide advance notice in order for

you to make the necessary modifications in order to maintain uninterrupted service.
