Table 3-371  Parameters for the advanced attributes of a PW

Parameter

Value

Description

RTP Header

Disable, Enable the Huawei RTP, or Enable a Standard RTP

Default value: Disable

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

The RTP header is used to load clock signals.

Value description:
  • Disable: Indicates that the RTP is disabled.
  • Enable the Huawei RTP: Indicates that the Huawei RTP is enabled.
  • Enable a Standard RTP: Indicates that a standard RTP is enabled.
Jitter Compensation Buffering Time (us)

375 to 16000

Default value: 8000

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

The Jitter Compensation Buffering Time (us) parameter specifies the size of the jitter buffer.

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

Default value: 1000

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

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.

Ingress Clock Mode

-

Specifies the clock mode for the ingress PW of the CES service.

NOTE:

This parameter is inapplicable to PWs.

Egress Clock Mode

-

Specifies the clock mode for the egress PW of the CES service.

NOTE:

This parameter is inapplicable to PWs.

Enable CES Service Alarm Transparent Transmission

Enabled or Disabled

Default value: 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 value: 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 value: 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

Specifies the sequence number mode.

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

Control Chanel Type

None, CW, Alert Label

Default value: CW

Specifies the mode of PW connectivity check.

  • The value None indicates that the control word is not supported. That is, the PW connectivity check is not supported.
  • The value CW indicates that the control word is supported.
  • The value Alert Label Indicates VCCV packets in Alert Label encapsulation mode.
Association with other parameters:

If Control Word of the PW is Not in use, do not set Control Channel Type of the VCCV to CW; if Control Channel Type of the VCCV is CW, do not modify Control Word of the PW to Not in use.

VCCV Verification Mode

None, Ping

Default value: None

Specifies the VCCV verification mode. The VCCV verification is used for PW connectivity check.

If the VCCV Ping test is required, set this parameter to Ping.

Protection Mode

1:1 or 1+1

Default value: 1:1

NOTE:

The OptiX OSN equipment supports only 1:1.

The Protection Mode parameter specifies the protection type of a PW APS protection group.

Value description:
  • 1+1: The service is dually transmitted to the working and protection channels at the transmit end and selectively received at the receive end.
  • 1:1: The service is transmitted to the working or protection channel and is received from the working or protection channel based on the status of the protection group.
Recommendations:

When you create a protection group in 1:1 protection mode, the protection channel cannot be configured with extra services. For this reason, the actual applications of 1+1 and 1:1 protection groups are the same, except for the configuration.
