Zhone | Products | 317x | ACCULINK 317x Series E1 CSU/DSU

The ACCULINK 317x Series is a family of intelligent, full-featured E1 CSU/DSU multiplexer products providing an interface between an E1 digital network and a variety of customer-premise equipment, such as routers, front-end processors, video servers and digital PBXs.

The 317x E1 DSU/CSU series of products consists of a 2-port 3172 DSU/CSU and a 4-port 3174 DSU/CSU. Each unit acts as an interface between an E1 digital network (as specified in ITU-T standards G.703 and G.704) and the customer premises equipment, converting signals received from the DTE (Data Terminal Equipment) to signals that can be transmitted over E1 lines.

The 317x supports point-to-point and point-to-multiple point network applications, including Local Area Network (LAN)/Wide Area Network (WAN) interconnection, shared access to network-based services, and fractional E1 network applications. The 317x provides the capability to support fast, efficient, distributed applications, including remote file sharing, tele-collaboration, and “white boarding” in a most cost-effective manner.

ACCULINK 317x MANAGEMENT

Comprehensive, integrated management features means that the 317x CSU/DSU lets you easily configure, troubleshoot, and monitor your network using:

� Integrated Front Panel keypad and LCD

� ASCII Terminal Interface

� PC-based Front Panel Emulation Software

� Telnet and SNMP

Each 317x includes an integrated front panel display and keypad with an easy-to-use, easy-to-understand menu scheme that lets you configure, test, and monitor local and remote devices. The optional 317x Front Panel Emulation software enables you to configure, test, and monitor the 317x right from a PC. Enhanced functionality, multiple modes of operation, and expanded help menus make the Front Panel Emulation software straightforward to use.

Your Network Management System (NMS) can optionally “link” to the 317x, exchanging SNMP MIB traps, alarms, configurations, etc., via a breadth of schemes, including:

� PPP/SLIP router connection

� E1 in-band

� External modem

� 317x-to-317x daisy chaining
