Maximum Distance for NM-4B-U

[JustForVoice_2]

I need to Integrate a paging system with VG router using ISDN BRI. the manufacture for the paging system told us to use NM-4B-U module in our cisco router and I need to know what is the maximum distance supported between the two devices.

Few miles, as it is an U interface.

Check again with the manufacturer as NM-4B-U does not supports voice and they may not know what they're talking about.

Very nice.

We've already ordered the module. and we ordered two modules :)

The account manager will be very happy

About me, I evaluated you reply as extremely helpful but I did not check "Resolved my issue" because I have now new problem :)

No worries. When buying Cisco products, always make sure a reputable professional reviews everything before, because it's complicated stuff, and it's easy to make mistakes.

How I can know if the module support Voice or not?

[paolo bevilacqua]

The voice modules have V in the part number, like VIC, WVIC.
