Reply To: BHCC and BHCA

Farzad Tabrizi

In calculations provided by NEC corporation for NEAX switching system, they calculate the BHCA of subscribers as follow
((no o sub.*erlang of each*1.35*.5)*3600)/70
I can not understand the meaning of factors 1.35 and .5 on above relation. Can anyone help & explain those factor’s or me?
With best regards
