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 backup 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 NTIII applications, IBM0 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."

  • Hot-swappable modem cards, power supplies and control cards

The Zypcom Z32CH chassis system provides a growth path solution for dial-up networking applications. The Z32CH's modular design can be configured as a basic modem pool or an advanced network access solution that operates with your existing SNMP-V2 manager.

Central Site Consolidation

The Z32CH chassis provides a high-density rack-mounted solution for housing modems at a central site or LAN/Internet access point. Requiring only seven inches of vertical height, the Z32CH mounts in a standard 19-inch equipment rack, is convection cooled, and can be stacked up to nine high (288 modems) in a standard seven-foot cabinet.

Configuration Flexibility

The Z32CH's modular design accommodates three different chassis control cards (manual, LCD front-panel and SNMP-/WWWmanageable) to fit varying customer requirements. Four different power supply options (AC, DC, dual AC
and dual DC) are available. With three different modem cards for a wide range of modulation types and speeds, the Z32CH allows you to configure the system that your application requires.

Front-Panel Control

Zypcom's rack-mounted modems contain status and interface LED displays. To augment the modem LEDs, the LCD-equipped Z3200 control card adds full front-panel and VT100 port control. The Z3200 control card can address one to thirty-two modems in the Z32CH chassis and allows for configuration, diagnostics, and monitoring. All modem software based-features can be controlled from the front-panel LCD or the VT100 port either locally or remotely.

SNMP Management

The Z3200E control card adds an embedded SNMP agent to the Z32CH chassis. The Z3200E's MIB-IT agent complies with RFC 1696 and allows for fault monitoring, diagnostics, configuration, security management, operational statistics and new firmware downloads. The Z3200E controller can work with your existing SNMP client or with the Zypcom-supplied SNMPc by Castle Rock to lower network operating costs and maximize access.

WWW Access

The Z3200E controller also includes an embedded WWW server for managing your Zypcom modems and chassis with a Web browser. Use your browser over the WWW or across the corporate LAN to access the Z3200E's home page for complete modem management capabilities.

The Intelligent Choice

The Z32CH is a full-featured network access solution for traditional mainframe and minicomputer access to the newer client/server and remote LAN node applications.
