Data Communication (V.35, V.24, 64Kbps Co-directional) Wireless (Cellular, Microwave Radio) Communication. Interconnecting computer terminals. Interconnecting LAN (Local Area Networks). Providing leased data lines and real-time video links to subscribers at speeds ranging from 64Kbps up to 1.024Mbps, using the "N"x64, V.35 data interface card. G.703, Co-directional, synchronous data 64Kbps. V.35, synchronous data 64Kbps."N" x 64Kbps, V.35, user configurable, synchronous data interface. The value of "N" may by configured by the user according to bandwidth requirements. V.24 / RS232, asynchronous data interface for low-speed data applications ranging from 300Bps to 19.2Kbps. BRI ISDN “U” Interface. VCL-30, E1 Voice & Data Multiplexer
