High SDCCH drop with cause : ERR IND T200 expired !!

[fahmi]

Dear All,

We face a strange behavior of SDCCH Call Drop due to ERROR IND received on SDCCH (T200 Expired).

What could be the reason ??

Hmmm.... Interesting...

Check if there any discrepancy in parameters.....like N200 SDCCH, SACCH etc etc.. Also check the loading of ABIS Link.

Moreover routine optimization like interference checking , SDCCH shifting and faulty hardware.

Err Indication is mostly because of T200 expiry and this happens due to multiple reasons, it can be due to radio quality or ABIS fluctuations.
