I think there is no formula to convert Megabytes traffic 2 erlang since the Erlang is a unit of measurement of “intensity” of voice traffic, not a measure of saturation throughput of a connection.
Unless there is an extented definition of “ERLANG”..
Any additional clarification will be welcome..
I think NIce Guy is very right , there is no direct calculation for converting Data Traffic to voice traffic or vise versa.
all This calculation found in Internet is for Voice over IP or simple term when channels/TC are very fixed ie 1 or 2 ch/TC, may ch having capacity to deliver 64 Kbps, can calculate the erlang to Kbps.
but when throughput is depend on, dynamically used Time slot and depend on request of Terminal
