chronization of Submaster/Slave
IP-CS is in a gap state)

Specify the CODEC list which is used to nego-
tiate the CODEC type and payload size be-
tween location groups to each location number
assigned by CMAD Y=29.
[Series 3200 R6.2 software required]
NOTE 1: This data setting is valid for the
voice packets that are sent to the
group that is set to “ZZ” in the first
data from the group that is set to
“XX” in the first data.
NOTE 2: The setting of small payload size is
effective for the voice quality mea-
sures in general, but the used band-
width becomes bigger. Set the
payload size considering the avail-
able bandwidth in the network.
