      Zypcom's SX-Series of modems are designed for commercial data communication applications. All SX-Series modems can operate on dial-up or point-to-point leased lines. The feature-rich SX-Series modems are proven leaders in data throughput — even on impaired telephone lines. Network World said "the best overall performer" of high-speed modems. Data Communications bestowed their "Top Performer" award. Byte said "sends and receives data faster than any modem." Zypcom's Z34-SX modem incorporates V.34 technology for line speeds up to 33.6Kbps. The Z32t-SX modem incorporates V.32terbo technology for 19.2Kbps line speeds. The Z32b-SX modem incorporates V.32bis technology for 14.4Kbps line speeds.

      Operational Flexibility

      The SX-Series modem family is a versatile network modem that offers a wide range of operational flexibility as well as application flexibility. SX-Series modems are ideal for mission critical applications over dial-up lines, 2-wire leased lines or 4-wire leased lines. Advanced leased line back-up over a single dial-up line reduces your restoral line costs by 50% compared to dual-line back-up modems.

      Application Flexibility

      SX-Series modems are ideal for router-to-router communications, remote LAN and Windows NTTM applications, IBM® synchronous communications, disaster recovery and X.25 network applications. The SX-Series family of modems have multiple autodialing protocols for compatibility with a wide range of computer hardware. Sophisticated remote diagnostics and modem control, combined with an optional PC-based SNMP network management system and features too numerous to mention, deliver unmatched performance, reliability, and functionality. On the Z34-SX, future controller and DSP enhancements are added quickly with the flash memory design.

      One Modem, Lower Costs

      With its operational and application flexibility, ease-of-use, compatibility, security options, manageability, superior signal-to-noise performance and the highest full-duplex data throughput of any modem today, the SX-Series offers the data communications professional the best price/performance ratio available. Network World said "Zypcom provides the biggest bang for the buck."
