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

[Voll, Scott]

What are you seeing?

Look at the Prerequisites on the second doc.  

"Digital interfaces that use the TDM switching feature must be on the same network module. It is not possible to switch non-voice traffic across a router backplane to a different network module."

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

>>I need some advice regards NM-HDV2-2T1/E1. Does this module can be used to perform ISDN dial backup ?
>>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 ?
