This object specifies the packetization period for a
particular CODEC in VBD (Voice Band Data) upspeed.
The packetization period represents the time for the
media gateway to collect the data from TDM side before
it sends out the packet.
This object is not applicable if cvapCodecConfigAdaptType
is set to 'aal2(4)' since the packetization period for
a CODEC in VoATM with AAL2 depends on the associated
profile.
