asterisk users - Nov 2004 - Can isdn data calls routed through 2 t100p's

I have a pri comming into a t100p in my asterisk box.  I have a second t100p
configured as pri_net connected to a nas server.  I can route modem calls to the
NAS with no problem, but I am concerned about isdn data connections.

Will asterisk route 64k isdn calls between 2 t100p's?  Also, should I expect
worse modem connections than normal?

It is possible to make your ISDN calls terminate on the asterisk boxs
with ZapRas. While I haven't tried to connect any data to anything
outside of asterisk, it should just work. Same goes for your modems. The
echo cancellers should drop out and leave the modem with the pure phone
call.

Not exactly what you asked, but Asterisk routes Unrestricted Digial 
connections between two pri:s on the same TE405P for us. I guess it should 
work between two T100Ps as well. 

There are differences between the two setups. When using separate cards
you have the possibility of timing slips since the clock can not be
carried from one card to another. Also, when bridging within a card the
data stream does not have to touch the pci bus / main cpu.
