Hi Plannerguy,
None of these reports have direct correlation with T200 Expiries,
Both the reports show how much percentage of SDCCH Call faliures are on ABIS, A & Air interface. But there is no separate counter for T200 because ABIS failures include so many other things in addition to T200!

So, is there any other counter to check T200 expiries?

Hi

Pls check with counter 20476 or 20065. it will tell the number of L1 errors and the number of T200 timeouts.

Else Use MML command ZDWN will specifically tell whole data.

According to the counter description for 001013, T200 is included:

When a TCH transaction ends because of a radio failure and the RRM releases the TCH. This counter is typical in connection with coverage problems. ERROR INDICATION is sent by the BTS to the BSC in the following cases:
- Sequence error in a received message (the case where retransmission is not possible).
- Timer T200 has expired N200 +1 times (MS does not respond any more).
- Unsolicited DM response when link is established.

This T200 expiry in counter TCH radio Fail is related to T200 FACCH drop not T200 SDCCH drop.

Hi Ice,

You can have it by using CTR/MTR(Cell/mobile traffic recording). You have to search for specific event & cause code in the output file. For T200 expiry(T200 expired (N200+1) times, abnormal release), event code is 16 and cause code is 1.

Thanks,
Osman

Why we have T200F and T200S "0 ms -BCF PREDEFINED VALUES" ??? Is it better to change it? What are the suitable values for NSN?

Regards

Hi ,

you can use T200S =1000 ms freely.
It will improve your CSSR.

Hi,

It is basic feature from S11.
License is activated by default. value of the time T200S is 0 ( meaning 220 ms ).
You can check parameter dictionary ( it is BCF object not BSC or segment ).
