quick question: Is their a difference in the PBXDI-AA (rs232)
and the PBXDI-AB(V.35) --MODULES-- . The cabling is different
of course , but are the modules the same? The PSP indicates
they may be different, The modules have different variants on
the part number.
A customer has a -AB version and wants to know if all he needs is
a cable swap to be able to use the card with RS232 cables.

Based on your description (I don't have the 'official' description
immediately to hand) the modules are the same EXCEPT the jumpers
are set for 2 V.35 ports OR 2 RS-232 ports. So, starting with a
two port V.35 module, to convert to a two port RS-232 module you can
1) change cable to the two port RS-232 cable;
2) change the jumpers on the board to the RS-232 setting.
There are five jumpers per port to change. The jumper change procedure
is described in the installation manual that should have come with the
card - the same manula that describes how to set the CSR addresses.
