No.
Actually, it is, using an Adtran

cards can handle E1 or T1, and if you go E1 you'll get 30 channels instead

I have talked to a number of telcos in the US about this... they don't
have the ability to do it.

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
I have a T3 coming from my carrier. From there I want to use an Adtran
mx2800 T1 Mux to break the T3 into 28 T1/PRI which feed into seven quad
T1/PRI equipped servers.
Everything seems very straight forward with the exception of the D
channels for the T1/PRI.

Your mux will split the DS3 into 28 DS1 (T1) circuits. They are
numbered 1 - 28. You tell your carrier how and where to assign the D
channels. The mux does not have anything to do with D channels or
signaling; the telco's ISDN switch does.
A simple setup would have a D channel on every DS1
Thanks for some answers, that is what I thought.
Asterisk is NFAS capable so I am looking at seven D channels on the T3 I
guess. I don't want to put a D channel on each T1 or I will lose
several channels that could be used for calls.
I wonder if there is any way that Asterisk can do NFAS

I am unsure of * capabilities on NFAS (we do not use PCs to terminate

same bus though.
