The WAN-in-a-Can range of LAN extender products extend LAN connection over a wide area link. The integrated 4-port LAN switch supports local switching , thereby removing the need for external switches or hubs in smaller LAN installations. Full wirespeed 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 link. Different WAN-in-a-Can models support E1 , E3 and DS-3 leased line links, and also serial X.21 and V.35 connections.

Rear: WC3445 - Ethernet over E3/DS3
The WAN-in-a-Can family requires no configuration in most installations, and is truly "plug and play". The subscriber ports are auto-sensing and support both 10M and 100M in full or half duplex modes. Manual selection of 100M FD operation enables connection to fixed port routers. 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 WAN-in-a-Can product to smooth out bursty traffic without packet loss.
For low bandwidth applications such as BT's Kilostream , the WC-X.21 and WC-V.35 models offer a choice of X.21 or V.35 DTE interfaces. The X.21 interface is presented on a 15 way D-Type connector and the V.35 on a 34 way M-rack connector. An external cable can be used to convert an X.21 interface into EIA-530 . The serial port operates in DTE mode, and requires the attached DCE to supply timing. The X.21 port may also be operated in a dual-clock, EIA-530 mode to support asymmetric operation.
The WAN in a CAN can easily be rackmounted in either a 1U two unit rackmount kit, 1U quad (4 x WAN in a CAN's) box or in a 6U eighteen unit rackmount kit.
THE WC1000 and WC3445 are also available in modular form for our 4U 12 slot managed centralised management option - MetroRack.
