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 acr

I am unsure of * capabilities on NFAS (we do not use PCs to terminate
any PRIs), but it allows bonding of desparate PRIs to use a single
d-channel. ie, you can have 1 d-channel (optional backups) for the
entire DS3. Not sure if * can communicate across cards like that in the
same bus though.

What I would really like to do is have one D channel coming in on the T3
and have it split between each of the T1/PRI or even better one D
channel per quad (I know Asterisk can do that).
Is it possible?
No.
Actually, it is, using an Adtran Atl

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

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
