The "WAN-in-a-CAN" WC-155 provides a low cost, high performance LAN extension over fibre. The WC-155 uses GFP (Generic Framing Procedure) encapsulation over a selectable OC-3 or STM-1 155.52Mbps fibre interface. The WC-155 is a virtually "plug and play" device with configuration options selectable on bit switches where non default operation is required.

The WC-155 provides a single user port presented as an RJ45 supporting a 10/100BaseT interface. Auto-negotiation and automatic MDI/MDI-X crossover switching are available by default, though full manual control is available using the bit switches. The user port will perform MAC address based filtering of local packets and will forward all other packets.

The "WAN-in-a-CAN" product family performance is shown in the table below and shows the maximum performance gained against a LAN tester, and also the performance when overloaded with wire speed LAN traffic, 148810 pps.

In more complex installations using VLANs, the "WAN-in-a-CAN" supports large frames up to 1522 bytes thereby allowing the transport of VLAN tagged packets.

The WAN port is presented as a duplex SC Fibre transceiver and variants support Multi-Mode, Single Mode Short Haul and Single Mode Long Haul applications. The WAN interface operates at 155Mbps and supports either SONET OC-3 or SDH STM-1 framing. The WC-155 offers both internal and loop timing modes. LAN traffic is transported across the WAN using the GFP (Draft
Rev 2 ANSI T1X1.5). The WC-155 requires the full OC-3 or STM-1 bandwidth to transport the user LAN traffic and offers full wire speed, full duplex operation.

For critical applications, an external alarm relay is provided to indicate power failure and WAN port alarm conditions. LEDs also indicate unit status.

The WC155 can easily be rackmounted in either a 1U two unit rackmount kit, 1U quad (4 x WC155) box or in a 6U eighteen unit rackmount kit .

Also available in modular form for our 4U 12 slot managed centralised management option - MetroRack.
