Chapter 1 INTRODUCTION The 2864 series of V.34 modems includes three sub-series of models, namely the Supreme, Elite and Omni series. The Supreme and Elite series models have ISDN capability or can be upgraded to have ISDN capability. The Omni series does not have ISDN capability. The Supreme series provides an LCD display panel while the Elite series has a front panel with LED indicators only. Many features are common to all three series. If not noted otherwise, a feature illustrated with one series model in this manual applies to the other models and series as well. The Elite 2864 series of high-speed modems features four base 10models. They differ only in the implemented line interface module, everything else is equivalent except for the panel LED indicator designations. The models are Model Name Elite 2864 Elite 2864L Elite 2864I Elite 2864IU Line Interface Module Dial-up line DAA Dial-up and leased line DAA ISDN S-interface ISDN U-interface Phone Line Used Dial-up analog PSTN line Dial-up and/or 2/4-wire leased analog line ISDN line, S-interface ISDN line, U-interface The Elite 2864 has a 2-wire dial-up line DAA (Direct Access Arrangement) module for connection to a normal PSTN (Public Switched Telephone Network) 2-wire dial-up phone line. The Elite 2864L has a DAA with both a dial-up and leased line interface. A 2 or a 4-wire leased line can also be used besides the normal 2-wire dialup line. Dial back-up capability is provided while using leased line. The Elite 2864I has an ISDN S-interface module that will connect to an ISDN S-interface line. It will connect to an ISDN call or a modem/fax call from PSTN made to this ISDN line. A U-interface ISDN module is available for the USA market. The Elite 2864IU is the ISDN model with the U-interface module. By changing the line interface module, one Elite model will essentially become another Elite model. Each Elite model has different markings on its front and rear panels. Thus, in addition to the line interface module the front and rear panel also need to be changed in order to transform one Elite model into a different Elite model. Note that each Elite model has its own telecommunication authority approval 1-1
