Ethernet Extender over E1 with Management, WCM1000 Datasheet

Metrodata Limited

The WCM1000 Ethernet extender product offers a simple "plug and play" method to extend a LAN connection between multiple sites using an E1 2Mbps G.703 leased line, whilst also offering extended management functionality.

The integrated 4-port Ethernet switch supports local switching, thereby removing the need for external switches or hubs in smaller Ethernet installations. VLAN support is also offered.

WCM1000 Overview Diagram

This application shows two LANs connected together using an unframed E1 2M G.703 leased line, such as a BT Megatream-2 circuit. As a plug and play Ethernet switching device the WCM1000 is a straight forward and cost effective alternative to the use of routers in small and medium sized networks. VLAN support and remote management allow the simple implementation of sophisticated solutions.

Full wirespeed switching and filtering between the 10/100 BaseT LAN ports is supported so that only packets destined for the remote site are forwarded over the E1 2Mbps G.703 leased line.

For simpler installations the WCM1000 requires no configuration, and is therefore truly "plug and play". The subscriber ports perform auto-negotiation and support both 10M and 100M operation in full duplex (FD) or half duplex (HD) modes. Manual selection of 100M FD operation enables connection to fixed router ports. Cabling issues are minimised through the use of automatic MDI/MDIX selection on these ports.

Sophisticated management functionality is offered either locally or remotely using Telnet and SNMP, with multiple levels of security for user access available. Telnet offers a simple menu driven method of changing all configuration parameters as well as analysing the extensive performance statistics that are available. Using SNMP a network manager will have full GET/SET access to all configurable items. SNMP access is restricted to authorised NMS systems, which will receive SNMP traps offering unsolicited remote notification of problems.

The highly efficient HDLC encapsulation of packets ensures that maximum throughput is achieved on the WAN link. Internal packet buffering enables each WCM1000 to smooth out bursty traffic without packet loss.

The WCM1000 can easily be rackmounted in either a 1U two unit rackmount kit, in a 6U eighteen unit rackmount kit or is available in a 1U quad box (1U rackmountable unit containing 4 x WCM1000 units).
