hi,
these timers are used in TBF Drop Rate detection... it's like the radiolink timeout for the call drop rate. Increasing it to the max means that the user feels like the network is "frozen" and will probably stop the packet connection by himself.
On top of that, the TBF is not released for a very long time, which should increase the TBF congestion rate.
In the end, I doubt it is a good idea to increase these "Nxxx" counters to a value that's too high. It's an artificial fix that only enhances the KPI, but not the end-user qos.
(that's just my opinion on the topic...)
Regards

| @Bill:I have changed the value of these parameters in my network to full value 250 each and now my drop rate is around 0.70 to 0.80 |

vicky,
no, i can't (no time, sorry)
you have to try them, and see the effects by yourself. |

@Vicky
The values are

N3103 = 10
N3105 = 10
All are default Siemens recommended values. |
