Ah, yes a good point.  As mentioned at:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123cgcr/dial_r/dia_c1g.htm#wp1108669

the default is 56K and the output of the "show service-module" confirms 64K
channels:

rio_rancho_management_router#show service-module Serial0/1
Module type is T1/fractional
~    Hardware revision is 0.96, Software revision is 0.2,
~    Image checksum is 0xED22BEC5, Protocol revision is 0.1
Receiver has no alarms.
Framing is ESF, Line Code is B8ZS, Current clock source is line,
Fraction has 24 timeslots (64 Kbits/sec each), Net bandwidth is 1536
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This mismatch would certainly cause a framing error :-)
