Which ds0-group option should you select to send automated number identification information on
outbound calls for this digital T1 voice circuit?
A.
e&m-fgd
B.
e&m-fgd
C.
fgd-eana
D.
e&m-delay-dial
E.
fgd-os
Explanation:
E&M signaling is often the preferred option for CAS because it avoids glare, it provides
answer/disconnect supervision and it can receive Automatic Number Identification (ANI) with FGD
and send ANI with FGD-EANA. In other words, you can have 1 channel-group for incoming calls and 1
channel-group for outgoing calls.
