LAN Extension over an E1 2Mbps G.703 leased line

The MetroCONNECT WC1000 unmanaged LAN extender product offers a simple entry level 'plug and play' to extend a LAN connection between multiple sites using an E1 2Mbps G.703 leased line. The integrated 4-port LAN switch supports local switching, thereby removing the need for external switches or hubs in smaller LAN installations.

WAN-in-a-Can Overview Diagram
MetroCONNECT WAN-in-a-Can : the "plug and play" way to connect LANs together over the WAN

Full wire speed 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.

In most installations the WC1000 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.

The highly efficient HDLC encapsulation of packets ensures that maximum throughput is achieved on the WAN link. Internal packet buffering enables each WC1000 to smooth out bursty traffic without packet loss.

The WC1000 supports a maximum packet size (MTU) of 1536 bytes which is sufficient to transport double VLAN tagged frames (Q-in-Q).

The WC1000 can easily be rack mounted in either a 1U two unit rack mount kit, in a 6U eighteen unit rack mount kit.

The WC1000 is also available in a card based format for use with the 4U 12-slot MetroCONNECT managed chassis.

Connecting two LANs together using an unframed E1 2M G.703 leased line

This application shows two LANs connected together using an unframed E1 2M G.703 leased line, such as a BT Megastream-2 circuit. As a plug and play Ethernet switching device the WC1000 is a straight forward and cost effective alternative to the use of routers in small and medium sized networks.
