Actually every US made switch I've ever seen is 2.048MHz to the core. 
They then rate change to the T1s. It makes export easier to handle. Any 
mixof E1/2/3.. or T1/2/3..  cards will just plug in and go timing wise. 
The issue is probably more of not being set up for mixed ulaw/Alaw 
working. I don't think anyone is really set up for that within the switch.
