A SS7 (C7) Signalling Link should be dimensioned so that it can handle a maximum signalling load of 40%. The value six is a weighting factor. MSUs supports the different SS7 messages: IAM, IFAM (BTNR 167), ANS, REL, CPG, etc..

Link sets should be dimensioned so that they contain a maximum of 16 signalling links. An odd configuration will lead to an imbalance with the load distribution.

Dear, Baas!
Could you write the complete equation?
Probably, '6' is average number of MSU for one connection.
