Re: MPTN/Anynet... on V4R1

["Lou Schmaus" <lschmaus@xxxxxxxx>]

Chuck,

We did something similar at on of our customers earlier this year, although
we only had one remote location. Upgraded the 494E to a 594E(with ethernet
AND twinax), added a Cisco 1601 on the /400 side, and put an ethernet card
in the /400. Also, we kept the 56K leased line. The 594E has a way of
fooling itself into thinking there is a frame connection. So we kept our
CSU/DSU's, got the /400 talking to the network, and got to start taking the
twinax cards out of the PC's, all for about $6000-$7000 total. Perle tech
support was very helpful throughout the process.

By the way, they noticed no degradation in response time, even though they
added another half a dozen connections to the /400 through the new ethernet
connection at the remote site.
