Chapter 2. Support of PU2 Platforms
The CNA-8000 supports PU2 platforms by means of a XCA-styled PU2 Gateway
function. With FICON and/or ESCON as the upstream connection, PU2 platforms are
supported on Ethernet and Token Ring. Both PU 2.0 and PU 2.1 platforms are supported.
Use of XCA technology makes the CNA-8000 a perfect replacement for Cisco CIP and
CPA products as well as a replacement for the 3745 Token Ring Gateway function.
Existing switched VTAM definitions and XCA definitions should be able to be used “as
is”.
IBM 3174 gateways, Memorex Telex/Visara 1174 gateways, and McData/ Memorex
Telex 1374 gateways can also be replaced easily but with a few more gen changes on the
host.
The following illustration shows what the network may look like with a CNA-8000.
