Dear ninjafine,
Could you please share the formula, meaning & usage of below mentioned counter in your PPT
(Erlang Minutes between drops) on NW Level

Hi! Usually this one is used:
Erlang Minutes per Drop (EMD) = Traffic Volume (Erlang) x 60 / No of call drops.
Definition: Total of Erlang minutes in one period measurement per drop call.

Gentlemen, I would like to take a doubt. On my network changed the parameters T305 and T309 using the default value of Radio link. If I change the radio link to the maximum value using the values ​​of T305 and 309 would increase the number of drops?

The default value of the counters in the MSC currently allows low drop call is performing the disconnection before the end of the MS T200 correct?

Hello Can you please share default value for below

T305
T309
T200
T3019
Alos which formula is correct

T305 + 2*T308 < (N200+1)*T200

or
T305+2*T308+T3109<(N200+1)*T200

Thx
