RTP Head

Disable or Enable the Huawei RTP

Default: Disable

The RTP Header parameter specifies whether the RTP header function is enabled.

The RTP header is used to load clock signals.

Source Jitter Compensation Buffering Time (us) 375 to 16000

Default: 8000

NOTE:
The OSN 580 supports the value range of 875 to 16000.

Specifies the jitter buffer size of the service source.

The jitter compensation buffering time is configured to absorb jitters on the network side.

Impact on the System:

The jitter compensation buffering time affects the delay of services.

If the jitter compensation buffering time is set, the subsequent operations are performed after the system has received packets for more than a half of the jitter compensation buffering time.

Recommendations:

The value of the jitter compensation buffering time ranges from 125 to 64000 in steps of 125.

Association with other parameters:

The packet loading time is closely related to the jitter compensation buffering time. The jitter compensation buffering time must be greater than double packet loading time.

Sink Jitter Compensation Buffering Time (us) 375 to 16000

Default: 8000

NOTE:
The OSN 580 supports the value range of 875 to 16000.

Specifies the jitter buffer size of the service sink.

The jitter compensation buffering time is configured to absorb jitters on the network side.

Impact on the System:

The jitter compensation buffering time affects the delay of services.

If the jitter compensation buffering time is set, the subsequent operations are performed after the system has received packets for more than a half of the jitter compensation buffering time.

Recommendations:

The value of the jitter compensation buffering time ranges from 125 to 64000 in steps of 125.

Association with other parameters:

The packet loading time is closely related to the jitter compensation buffering time. The jitter compensation buffering time must be greater than double packet loading time.

Packet Loading Time (us)

125 to 5000, with a step of 125

Default: 1000

The Packet Loading Time (us) parameter specifies the packet loading duration.

The efficiency of packet loading can be improved after the packet loading time is set.

Impact on the System:

The packet loading time affects the number of frames of E1 signals in each packet.

Recommendations:

The value of the packet loading time ranges from 125 to 5000 in steps of 125.

Association with other parameters:

The packet loading time is closely related to the jitter compensation buffering time. The jitter compensation buffering time is suggested to be greater than double packet loading time.

If the PW is bound with services, Packet Loading Time cannot be changed.

Enable Alarm Transparent Transmission

Disabled or Enabled

Default: Disabled

Specifies whether the alarm information of the CES service can be transparently transmitted.

If this function is enabled, the fault on the AC side of the CES service is notified to the remote end. On receiving the fault notification from the network side or the remote end, the local NE inserts the corresponding alarm on the AC side.

Threshold of Entering R Bit Inserting Status

1 to 65535

Default: 100

Specifies the threshold of entering R bit inserting status.

If the alarm information of the CES service is transparently transmitted and the number of consecutive lost packets crosses the threshold, the logic inserts the R bit to the network side and reports the corresponding alarm.

Threshold of Exiting R Bit Inserting Status

1 to 65535

Default: 5

Specifies the threshold of exiting R bit inserting status.

If the number of consecutive lost packets crosses the threshold, the logic quits inserting the R bit to the network side and reporting the corresponding alarm.

Sequence Number Mode

Huawei Mode or Standard Mode

Default: Huawei Mode

Specifies the sequence number mode.

The Sequence Number Mode must be set to the same value at both ends of a radio link.
