Waiting your input team

Did you check errrors on DIP ? check UAS ,SES,ES . Also check if no of devices of E1 are sufficently allocated .

[luganomu]

E1 Ts are enough E1 per 3/3/3 using abis optimization

[radenmohawk]

Have u check PGWLoad and PGW utilization in BSC?
How about other cells using ABIS optim in that BSC, did it had same case?

Increase CONFAACT on TG most probobly problem will be solved ; Actually problem is coming due to high Abis load

We got the Solution for DAR228. Site remove and recreated again by config team. Issue is now normal. we think the is was in Transceiver handler

Three reasons: 1-Transmission problem (get the DXU Log and Search for Word called (TERR) if it is So Many (more the 50) refer to TX team 2- problem in PCU/TRH/TRAP check the Bsc Load TRH/PCU/transcoder 3- check the SD congestion and Paging Load , Apply the Feature of MCcCH and Distribute the SD between the Channel groups

Other options: If you have access to ROMT or ROMT over IP, in your BSC, Maybe it can help to extract the RBS/DXU/DUG Logs. . .
