GPON BWIDTH Profile

Port

Port number

Index

A unique Id number for the OLT.

ONU ID

The ONU number for this OLT to which we are allocating bandwidth.

Cannot be greater than number of ONUS for the OLT.

This field cannot be changed once the alloc-id has been created.

Guaranteed BW (KB/S)

Specifies the upstream bandwidth for the GEM port. The value should be multiple of 512 and cannot exceed 1,048,576 Kbps.

Note that the guaranteed-upstream-bw is for CBR and UBR only and not used in DBA. If DBA is disabled the guaranteed upstream bandwidth should be non-zero.

Traffic Class

Specifies the upstream traffic class value. This is not used in DBA.

Values:

cbr Constant Bit Rate. The CBR class of traffic is used by connections that require a constant and guaranteed rate. The sampling time for CBR is constant, with no delay.CBR would be appropriate for real-time applications, such as voice and video applications.

ubr Unspecified Bit Rate. The UBR class of traffic does not specify traffic-related guarantees. No numerical commitments are made with respect to the packet loss or delay. With UBR service, the available bandwidth is fairly distributed to the active UBR subscribers. UBR would be appropriate for delay-tolerant or non-real-time applications, such as data application.

Default: ubr

Compensated

CBR compensation mode. Sometimes CBR access will be skipped after OLT and ONU exchanged GPONOAM messages. If you select true in compensated mode, CBR access can be compensated immediately after exchange of the GPON OAM messages to prevent possible jitter of the CBR channel.

Compensation mode is used for both DBA and non-DBA.

Default: False
