The WC3445 LAN extender offers a simple "plug and play" method to extend a LAN connection between multiple sites over E3 or DS3.
The integrated 4-port LAN switch supports local switching, thereby removing the need for external switches or hubs in smaller LAN installations.
LAN Extension over E3 and DS3 leased lines
The WC3445 product has now been superceded by the much more flexible and fully manageable MetroCONNECT WCM3100 product which offers advanced functionality at a cost-effective price point. The WC3445 is no longer available.

This application shows two LANs connected together using an E3 leased line, such as a BT Megastream-34 circuit. As a plug and play Ethernet switching device the WC3445 is a straight forward and cost effective alternative to the use of routers in small and medium sized networks.
This application shows two LANs connected together using an unframed clear channel DS3 leased line, such as a BT Megastream-45 circuit. As a plug and play Ethernet switching device the WC3445 is a straight forward and cost effective alternative to the use of routers in small and medium sized networks.
N.B. Care must be taken when using the WC3445 with services which are terminated in North America as the WC3445 requires clear channel DS3 circuits for correct operation.
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 E3 or DS3 leased line.
In most installations the WC3445 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 WC3445 to smooth out bursty traffic without packet loss.
In auto-negotiation mode the maximum packet size (MTU) is 1518 bytes for non-tagged frames and 1522 bytes for VLAN frames which is sufficient for passing single tagged 802.1q VLAN frames. In fixed 100M full duplex mode the MTU is 1536 bytes which is sufficient to transport double VLAN tagged frames (Q-in-Q).
The WC3445 can easily be rack mounted in either a 1U two unit rack mount kit, in a 6U eighteen unit rack mount kit or are available in a 1U quad box (1U rack mountable unit containing 4 x WC3445 units).
