Hey all (especially Kevin, Mark G, Carl, etc),
About 2 years ago I got feedback on this forum for a multiplexing protocol
convertor we were putting together. It is "soaking" with what we believe are
the last bug fixes presently in a test lab and should go to Beta early next
week. After 7 weeks in Beta, it will go into the 4 largest Digital Central
Offices in the world to allow various Support Systems enhanced access to the
switches and monitoring equipment located therein. After that, it will be
gradually released to other Digital Central Offices.
FWIW, here's what we ended up with:
1 Motorola MVME 147 (68030, 8 mb, 150mb disk) running os9, a board-to-board
routing application, X.25 network access applications, and Support System
interfaces.
1-18 Motorola MVME 333-2 (68010, 512kb ram, 64kb rom) running os9, and level 2
and 3 of any of several protocols, or a user-interface. These have 6 ports
available for async protocols and 2 ports for sync.
We have our own block-serial file managers (bfm and pfm) that handle (along
with block-serial drivers) data transfers between the 147 and the 333's and
read and write access to the 333's ports.
The 333's are just devices to the 147 (/slot3, /slot4, etc) and vice-versa
(/host). We get about 400 512-byte packets/second composite backplane data
transfer with our application fully loaded and running.
Bill West, Inc (comprised of Bill West) wrote the backplane driver and file
manager with help from developers on our team. GCOM, Inc licensed the X.25
level 2 and 3 drivers for network access and access to equipment that has X.25
interfaces directly to us.
Thanks for the input at the time!
Mark
