Market value (communications engineering)

Traffic balance in communication theory

In communications technology, the traffic value  y is the traffic volume  Y, which relates to an observation period t:

${\displaystyle y={\frac {Y}{t}}}$

The market value is measured in Erlang . So if a line is observed for an hour and a total of 30 minutes of that is busy, it has a traffic value of 0.5 Erlang.

The market value forms a basis for the dimensioning of communications systems.

Some market values ​​as an example:

• Connection of a telephone system : 0.2 Erl
• private subscriber line: 0.12 Erl
• Connection line in a local network : 0.8 Erl.
