We have to set up ISDN backup connection.
Can we use VWIC2-2MFT-G703 card for data call, so that Branch Offices with WIC-1B S/T ISDN cards can establish connection?
Or maybe with VWIC2-2MFT-T1/E1?
The router is Cisco 3845.
We know that this works with NM-1CE1T1-PRI card, and replacement for this NM is HWIC-1CE1T1-PRI but customer has only above cards.
We'll have 2 E1 ISDN-PRI links.
