We have 4 750's and one TSU 600 working with PC anywhere for data
communications for our support department.  We have on this system 2
T400P's.  The only thing I can say is who are you getting your timing from.
We are able to get modem calls and faxes without problems.  But this is only
using PRI from Allegenice.  We also have a LD service T1 from Sprint that is
in no way able to handle any data calls.  Our Adtrans are out of the box
without any changes to them.   This is our settings in our zapata.conf.

; Enable echo cancellation
echocancel=yes
;echocancelwhenbridged=yes
immediate=no
;adsi=yes
usecallerid=yes
hidecallerid=no
;callwaiting=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
musiconhold=default
signalling = fxo_ks

Hope this helps.
