Re: SDLC, 2793 and IOP-less mode

[Pat Barber <mboceanside@xxxxxxxxxxxxxxxx>]

It would appear that they are playing games with these
feature cards: Note the function available for iop-less.

I don't believe this would be the default on a new
system but you never know.


(#9493) - Base PCI WAN for ECS

The #9493 is a WAN with modem adapter that provides connectivity for IBM 
Electronic Customer Support (ECS) only. This feature is the non-Complex 
Impedance Matching (CIM) version offered in all countries except 
Australia and New Zealand. #9493 is functionally equivalent to #0614, 
#2793, and #9793, but #9493 indicates to IBM configurator tools that the 
IOA is being used by i5/OS in an IOP-less mode. When in IOP-less mode, 
the adapter function is restricted to communicating to IBM ECS on port 0 
(modem port). Port 1 is the RVX port and is not supported in an IOP-less 
mode.

Port 0 supports V.92 56K PPP, V.92 data modem, and V.44 data 
compression. Port 0 does not provide synchronous modem capabilities 
(SDLC and synchronous PPP).
