Wrong.  You can bond two B channels just fine with a TA.  I do it
all the time.

You can't do 128K, but you can do 115.2K.

Hard to say - depends on the RAS.  Most modern TAs will do multilink
PPP, but you'd need to make sure it's interoperable with the RAS.  I
just use a TA on each end for my link and let them speak their own
bonding protocol ("bonding mode 1" for the ADTRAN L1) so it works
seamlessly.
