Which codec is supported on the Cisco PVDM2 DSP modules but not on the PVDM3 DSP
modules?

A.
G.728

B.
G.729B

C.
G.729AB

D.
G.723

Explanation:
All codecs that are supported on the PVDM2 are supported on the PVDM3, except that the
PVDM3 does not support the G.723 (G.723.1 and G.723.1A) codecs. The PVDM2 can be used to
provide G.723 codec support or the G.729 codec can be as an alternative on the PVDM3
