Which configuration output indicates a properly configured T1 digital voice interface?
A. controller T1 0/0/0
framing esf
linecode b8zs
pri-group timeslots 1-24
!
B. isdn switch-type primary-ni

controller T1 0/0/0

C. isdn switch-type primary-ni

Then the answer should be A (without isdn switch-type )
Correct is C but without “isdn switch-type primary-ni” under controller T1, that command correctly input in enable mode.
Right,
use the command isdn switch-type switch-type in the global or interface configuration mode.
