The FEP-4600, by inclusion of the DLSw feature eliminates the need on the host side of
the network to move LLC2 protocol over the LAN and in some cases may result in a
simplified network. The host connectivity for the DLSw feature is the XCA feature
described previously. The downstream connectivity can be a router with DLSw capability
or some other device capable of communicating with RFC 2166, 1795, or 1434.

Note the improvements:

 DLSw feature moved from Router to the FEP-4600.
 Token Ring connection converted to Ethernet and possibly just a connection from

the FEP directly into the router.

 LLC2 protocol eliminated from the host side LAN
 If Visara 1174 remote controller used, elimination of LLC2 traffic from the

remote LAN as well.

 DLSw eliminated from the remote routers.
