But in the rest of the world besides The U.S. and Japan they use E1 lines
which give you 30 time-slots each. This means you could bring two E1's in
and have the full 60 dial-in users. I wish we had E1's instead of T1's
here :(

I use 5x10-modem cards in a PM3 with 2xCT1. This gives me two spare
modems and an extra slot (see below). Also the numbering is normal and
doesn't skip where the 9th and 10th modems *would* be on each card but
aren't since it is an 8-port card. :)

When Livingston upgrades our modem cards they will exchange any number of
modems; 6x8-port cards for 4x10+1x8 since they are both 48 modems. The
second instance would give you a spare slot.
