    Zypcom's L-Series modems integrate data and fax features into one reliable, low-cost communications solution. The L-Series product line includes an external and internal modem for computers using Microsoft® Windows 3.1/95. Both models incorporate V.34+ technology for line speeds up to 33.6Kbps. With V.42bis compression, data throughput can reach up to 115,200bps. Zypcom 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."

    Data and Fax
    In addition to advanced V.34+, 33, 600bps data mode capabilities, L-Series modems include the latest fax and voice features. Fax features such as 14.4Kbps line speeds, personal fax mail boxes, fax retrieval functions and fax-on-demand capabilities combine to offer the full fax functionality required at remote offices.

    The Z34-SL and Z34-PL are designed with flash memory for controller and digital signal processor (DSP) upgradeability. Future improvements and enhancements can be quickly downloaded to the modem through the PC's COM port.

    With its ease-of-use, compatibility, data and fax features, the L-Series modem offers the busy home/office worker the best price/performance ratio available. Network World said "Zypcom provides the biggest bang for the buck."
