Thanks Again TouchToneTommy !!
The next time I'll be traveling that way will be (roughly) in a couple of weeks and if I have enough time I will try what you've suggested.
The system is in place and functioning acceptably - all except for the PC Admin.
It was attempted from a total of 5 different PCs, some with normal serial ports, some with the USB to serial adapters - many times - and the best it did was to connect briefly, then fail.
Part of what -may- be wrong is that I did make my own cable by using the info I found here & at all the various articles I could find about it.
(Time & life simply did not allow me the luxury of buying a pre-made 355AF due to a forced & sudden house move.)
I suspect that the Admin port is what gave up, which means it may cast a shadow upon the ACS's main module and that perhaps it is time to seek a good deal on a spare.
The Cisco cable idea would have been possible a year or so ago - but since then I got rid of all the excess stuff I had sitting around and no longer have one.
Finally - I am also duplicating here what I've posted to the Avaya Support Forum in case it may be helpful for anyone else, or if anyone would like to clarify and/or condense it into a better form than I did:

I bought a serial cable already made up from Radio Shack.
I stripped back one end, matched the color wires to the pins using a continuity tester.
Then I soldered 1, 6 and 8 together and attached one wire to it.
Then I put a piece of heat shrink tubing over the end and crimped it to an RJ45.

Here a useful pinout for anyone who wants to connect their PC to devices such as key or PBX (Private Branch eXchange) phone system or other devices that have a serial port connected to a 8P8C jack. In fact, phone systems may have more than one port of this kind. For example, Avaya Partner ACS and Avaya Merlin Magix have two ports with this pin layout - the Admin port and the SMDR port.
Please note that there are several competing pinouts for this kind of connection. For example, Cisco console adapter has different pin layout even though it is also a DB9-to-8-pin connector device.

Ultimately what I did was to compare all the above for consistencies and used what was most consistent between all of them to connect a sliced off, nicely stranded CAT5 cable with a DB9 breakout adapter - and carefully verified correctness/connection via continuity.
As said above - it worked very well - for a while - and now it will not.
Thanks for any further info !!
