User's Manual 1028 Document #: LTRT-27045
Mediant 1000B Gateway & E-SBC
Parameter Description
The valid range is 20 to 65,000 msec. The default is 10,000.
Note: To enable No-Op packet transmission, use the
NoOpEnable parameter.
no-operation-interval
[RTPNoOpPayloadType]
Defines the payload type of No-Op packets.
The valid range is 96 to 127 (for the range of Dynamic RTP
Payload Type for all types of non hard-coded RTP Payload
types, refer to RFC 3551). The default is 120.
Note: When defining the parameter, ensure that it doesn't
cause collision with other payload types.
RTP Control Protocol Extended Reports (RTCP XR) Parameters
For more information on RTCP XR, see ''Configuring RTCP XR'' on page 837.
Enable RTCP XR
configure voip > media rtp-rtcp >
voice-quality-monitoring-enable
[VQMonEnable]
Enables voice quality monitoring and RTCP XR, according to
RFC 3611.
 [0] Disable (default)
 [1] Enable Fully = Calculates voice quality metrics, uses
them for QoE calculations, reports them to SEM (if
configured), and sends them to remote side using RTCP
XR.
 [2] Enable Calculation Only = Calculates voice quality
metrics, uses them for QoE calculations, reports them to
SEM (if configured), but does not send them to remote side
using RTCP XR.
Note: For the parameter to take effect, a device reset is
required.
Minimum Gap Size
[VQMonGMin]
Defines the voice quality monitoring - minimum gap size
(number of frames).
The default is 16.
Burst Threshold
[VQMonBurstHR]
Defines the voice quality monitoring - excessive burst alert
threshold.
The default is -1 (i.e., no alerts are issued).
Delay Threshold
[VQMonDelayTHR]
Defines the voice quality monitoring - excessive delay alert
threshold.
The default is -1 (i.e., no alerts are issued).
R-Value Delay Threshold
[VQMonEOCRValTHR]
Defines the voice quality monitoring - end of call low quality
alert threshold.
The default is -1 (i.e., no alerts are issued).
RTCP XR Packet Interval
configure voip > media rtp-rtcp >
rtcp-interval
[RTCPInterval]
Defines the time interval (in msec) between adjacent RTCP
XR reports. This interval starts from call establishment. Thus,
the device can send RTCP XR reports during the call, in
addition to at the end of the call. If the duration of the call is
shorter than this interval, RTCP XR is sent only at the end of
the call.
The valid value range is 0 to 65,535. The default is 5,000.
Disable RTCP XR Interval
Randomization
configure voip > media rtp-rtcp >
disable-RTCP-randomization
Determines whether RTCP report intervals are randomized or
whether each report interval accords exactly to the parameter
RTCPInterval.
 [0] Disable = (Default) Randomize
