Dear s.Vijay & Mohsin,
To calculate the signalling load between two Point codes u need to know
1) Total number of MSUs in an hour
2) Total number of Octets in SIF in an hour
3) Now each MSU = 8 + SIF Octets
using 1 , 2 & 3 u can find total number of Octets in an hour.
Now the signalling Traffic on a 64 kbps slot = (Total Number of Octets) * 8/64000/3600
Now u use above formula for both Tx and Rx direction and Maximum of this will give u effective traffic on this link in Erlangs.
