emtaSignalingVoiceJitterBufferType
(1.3.6.1.4.1.4413.2.2.2.1.6.4.3.0 Integer32)
This object contains the type of the jitter buffer. Setting this object
to jitterBufferTypeFixed(1) causes the eMTA to employ a fixed jitter buffer.
Setting this object to jitterBufferTypeAdaptive(2) causes the eMTA to
use an adaptive jitter buffer. If the jitter buffer type value is changed
through SNMP, then those changes take affect starting with the next phone
call (in process calls are not affected). When the voice jitter buffer
is frozen it uses the emtaSignalingVoiceJitterNomValue for the fixed size
of the jitter buffer."

emtaSignalingVoiceJitterNomValue
(1.3.6.1.4.1.4413.2.2.2.1.6.4.4.0 Unsigned32)
If the voice jitter buffer value is changed through SNMP, then those changes
take affect starting with the next phone call (in process calls are not
affected). This MIB sets the target hold time for the voice jitter buffer
in milliseconds. This is the initial hold time for the adaptive jitter
buffer. The actual target holding time will adapt above or below this
in response to observed network jitter. The MTA will reject all attempts
to set the value which is not within the interval defined by the
emtaSignalingVoiceJitterMinValue and emtaSignalingVoiceJitterMaxValue
MIB Objects. When the jitter buffer is frozen, this MIB controls the static
size of the voice jitter buffer. The default value is 0 which is interpreted
as the maximum jitter buffer size for the product.
emtaSignalingVoiceJitterMinValue
(1.3.6.1.4.1.4413.2.2.2.1.6.4.5.0 Unsigned32)
If the voice jitter buffer value is changed through SNMP, then those changes
take affect starting with the next phone call (in process calls are not
affected). This MIB sets the minimum hold time for the voice jitter buffer
in milliseconds. The target hold time cannot take on a value below the
minimum either through a MIB setting or through adaptation. That is, packets
