STARPLUS@ SPD 4696 Digital Key Telephone System INTRODUCTION SECTION 100 INTRODUCTION 100.1PURPOSE This manual provides the information necessary to program, install, operate and maintain the StarplusDigital Key Telephone System. 100.2REGULATORY INFORMATION (U.S.A.) The Federal Communications Commission (FCC) has established rules which allow the direct connec- tion of the Starplus Digital Key Telephone System tothe telephone network. Certain actions must be un- dertaken or understood before the connection of customer provided equipment is completed. A. Telephone Company Notification Before connecting the Starplus Digital Key Telephone System to the telephone network, the local serving telephone company must be given advance notice of intention to use cus- tomer provided equipment and provided with the following information: lThe telephone numbers to be connected tothe system. 0 The Ringer Equivalence Number also lo- cated on the KSU: 1.9Bl The Universal System Ordering Code (USOC) jack required for direct intercon- nection with the telephone network: RJ2l XFCC Registration Numbers: 8. c. - For systems configured as a key system: (button appearances)DLPHKG-74722-KF-E -For systems configured as a Hybrid system: (dial access codes)DLPHKG-74723-MF-E Incidence of HarmIf the telephone company determines that the customer provided equipment is faulty and pos-sibly causing harm or interruption to the tele- phone network, it should be disconnected until repairs can be made. If this is not done, the telephone company may temporarily discon- nect service.Changes in Service The local telephone company may make changes in its communications facilities or pro- cedures. If these changes should affect the useof the Starplus Digital Key Telephone System D. E.or compatibility with the network, the telephone company must give written notice to the user toallow uninterrupted service. Maintenance Limitations Maintenance on the Starplus Digital Key Tele- phone System is to be petiormed only by the manufacturer or its authorized agent. The user may not make any changes and/or repairs ex- cept as specifically noted in this manual. If unauthorized alterations or repairs are made, any remaining warranty and the software li- cense for the system will be voided. Notice of Compliance The Starplus Digital Key Telephone System complies with rules regarding radiation and ra- dio frequency emissions by Class A computing devices. In accordance with FCC Standard 15 (Subpart J), the following information must be supplied to the end user: !CAUTIONI1 “This equipment generates and uses RF energy and if not1installed and used in accordance with the Instruction- Man- / uat, may cause interferenceto Radio Communications. It /has been tested.and found to comply with the limits for a Class A computing device, pursuantto Subpart J o# Part 15 , of the FCC Rules, which aredesignedtoprovide reasonable/ protection against such interference, when operated in aj commerciat environmenf; Operation of this equipment in a! residential area is likelyto cause interference, in which case/the user, at his own expense, will be required to take what- //ever measures may be required to correctthe interference.” ! F.Hearing Aid Compatibility All Starplus Digital Terminals are Hearing Aid Compatible, as defined in Section 68.316 of Part 68 FCC Rules and Regulations. G. OPX Circuit The Starplus Digital Key Telephone System may be equipped with Single Line Adapters (OPX) modules which provide a 48V FCC reg- istered 2500~type single linebff-premise exten- sion interface pot-t. * Each OPX port when used to support an off-premise extension requires an OL13C network circuit. * An FCC registered interface such as a RJl 1 CNV is also required to connect to the public network.Issue 1, March 1994 100-I
