Phenomenon: When bindling the DBA for TCONT of new ONT during configuring GPON service, it displays “failed: bandwidth not enough”.
it displays “failed: bandwidth not enough”.
1. By inquiring the occupied equipment bandwidth resource, found that it almost reached 1.25G of summing the bandwidth of the bundled DBA type including fix or assure of configured TCONT.
2. Check the using situation of equipment TCONT, and release the occupied bandwidth resource of abandoned TCONT.
3. Success to bundle the DBA template with new TCONT.
Cause Analysis: the surplus bandwidth of OLT related PON is not enough and cannot meet the requirement of the parameters set in DBA.
The type of TCONT includes: type1, type 2, type 3, type 4 and type 5. When bundling one type 1, type 2, type 3, type 4 or type 5, once the TCONT type contains bandwidth with fix or assure type, the surplus bandwidth resource of PON will reduce related bandwidth accordingly. But the uplink bandwidth of PON is 1.25G. So if do not need to continue to use the TCONT of ONT, please delete the bundling of unused TCONT to release the uplink bandwidth resource.
