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 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.

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.
