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

Hi Marton,

Yeah but I'm little bit confusion because as stated here: http://www.cisco.com/en/US/partner/tech/tk652/tk653/technologies_tech_note09186a0080387544.shtml
the NM-HDV2 has "enhanced time division multiplexing (TDM) capabilities" which allow to switch
audio and data bit stream between ports on the same module. The ISDN signalization is supported
here. So I wonder since the NM-HDV2 can switch ISDN data bitstrem maybe it can terminate ISDN data too.
