I have a 2821 router with VIC2-BRI-NT/TE and I am connecting this to a U-port on Telos (BRI broadcast device) via a RJ11 cable. But Layer 1 Status is
DEACTIVATED. I think the issue might be related BRI S/T port of Cisco2811.
I am just wondering for this connection, does an external BRI NT1 is required for Cisco BRI port as VIC2-BRI-NT/TE is S/T port only instead of U-port? And which Voice Module has BRI-U port for this connection?
Very appreciated your help.
