About the HSIM-W6
The HSIM-W6 ( Figure 1 ) offers high-speed Wide Area Network (WAN) access to remote sites via
two WAN Port Interface Modules (WPIMs) to the device into which it is installed. The HSIM-W6
supports IEEE 802.1d transparent bridging, IP routing, IPX routing between the host device and
the two WAN connections, ISDN, Dynamic Host Configuration Protocol (DHCP), Network
Address Translation (NAT), and Inverse Multiplexing (IMUX) between Ethernet LANs across a
WAN resource. In addition, the ASYNC port connector can be used as a local console connection.
