The WC V.35 Ethernet extender offers a simple "plug and play" method to extend a LAN connection between multiple sites.

The integrated 4-port LAN switch supports local switching, thereby removing the need for external switches or hubs in smaller LAN installations.

Ethernet Extender over Serial V35 leased lines

Please Note:

The WC V35 product has now been superceded by the much more flexible and fully manageable MetroCONNECT WCM-Serial product which offers advanced functionality at a cost-effective price point. The WC V35 is no longer available.

Applications

Connecting two LANs together using a V35 leased line

LAN extension over V.35

This application shows two LANs connected together using a V35 leased line. As a plug and play Ethernet switching device the WC V35 is a straight forward and cost effective alternative to the use of routers in small and medium sized networks.

Delivering an asymmetric Ethernet service via a V35 satellite modem

LAN extension over V.35 satellite link

This application shows an Ethernet service delivered via a V35 satellite modem. In this application the WC V35 supports local switching, wire speed filtering and asymmetric data rates up to 20Mbps with an absolute minimum of overhead. This application requires another WC V35 unit at the other end of the satellite link.

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 V35 leased line.

In most installations the WC V35 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 WC V35 to smooth out bursty traffic without packet loss.

The serial port operates in DTE mode, and requires the attached DCE (e.g. leased line NTU) to supply timing.

The WC V35 can also support asymmetric operation with a V35 satellite modem.

The WC V.35 supports a maximum packet size (MTU) of 1536 bytes which is sufficient to transport double VLAN tagged frames (Q-in-Q).

The WC V35 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 WC V35 units).
