[cisco-voip] NM-HDV2 and ISDN data backup

[MIHI]

Sure, NM-HDV and NM-HDV2 support data, but I think they support only channel
groups, see this doc:
http://cco.cisco.com/univercd/cc/td/doc/product/software/ios123/123newft/123
t/123t_7/hdd_vfnm.htm#wp1046592 
"Up to 32 HDLC channel groups with a total bandwidth of 2.048 Mbps"
So they say "HDLC channel groups" not isdn PRI timeslots with data.

As far as I know it can be used for data:

used for data because the carrier card is voice only.

MFT-2T1/E1 card in a hwic slot, have internal DSP's, and I believe you could
then split the duty of the card.  The only potential issue would be the line
clocking.

>>Q&A
(http://www.cisco.com/warp/public/cc/pd/nemnsw/callmn/prodlit/sopra_qa.pdf)
is stated that it doesn't "...support integrated voice and serial WAN data
access over PRI" but I wonder about "INTEGRATED voice and serial WAN". Is
that mean voice and data couldn't be used on single interface, or at all ?
Can I configure E1 PRI (voice) on one port and E1 PRI (Data) on the second
and perform ISDN dial-in backup from other routers ?
