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.
