Connecting Ethernet over long distances normally requires Routers which require complex configuration.
However, Metrodata's LAN Extension products extend the plug and play functionality of Ethernet switches to join Ethernet LANs together, which means less equipment, fewer configurations and lower maintenance costs.
These LAN Extension products enable you to interconnect your local area network (LAN)/ Ethernet over a wide area network (WAN) without the need for expensive and complex routers. An example application would be to connect a remote office network to the headquarters over an external network. Metrodata also offers more sophisticated LAN extension and ethernet convergence products, see the MetroCONNECT Ethernet Service Delivery product range.
Connecting a remote office network to the head office over a leased line
Metrodata offer various solutions with their LAN Extension family:
- The WAN-in-a-Can family extend the plug and play functionality of LAN switches to provide LAN extension and Ethernet service provision over X.21, V.35, E1, E3, DS3 and STM-1/OC-3 leased line services
- The MetroCONNECT family provides managed LAN extension, Ethernet Demarcation and Ethernet Service delivery over E1/T1, E3/DS-3, STM-1/OC-3, and serial leased line services
- The LH1000 offers LAN extension over HSSI and serial interfaces, primarily designed to transmit LAN frames over satellite links via serial modems
- The LV2000 offers LAN extension over LVDS (EIA644) Crypto and satellite modems, as well as radio relay systems

The WAN-in-a-CAN® family enables Layer 3 Ethernet switches to be linked directly over the Wide Area Network (WAN)
The Metrodata WAN-in-a-Can range of LAN extension products extend LAN connection over a wide area link. Available for the following:
The Metrodata LH1000 is designed to enable the transmission of LAN frames across satellite links via serial modems. The LAN interface is auto-sensing and supports 10M, 100M, full or half duplex working. Manual selection of 100BaseT FD operation enables connection to fixed configuration router ports. The LH1000 supports a high speed HSSI port which operates at up to 110Mbps, and a medium speed multi-serial port which operates at up to 20Mbps over EIA530, RS449, X.21 and V.35, plus at lower rates over asynchronous RS232.

The LVDS DTE port can operate at asymmetric speeds since it is clocked using the DCE supplied Send & Receive Timing signals. The LVDS port is presented on a 25-way D-type male connector and supports data rates of up to 52Mbps. The LV2000 also offers Crypto Resync capability.
