Standard telegraph level

释义

In telecommunication, standard telegraph level (STL) is the power per individual telegraph channel required to yield the standard composite data level.

For example, for a composite data level of -13 dBm at 0-dBm transmission level point (0TLP), the STL would be approximately -25 dBm for a 16-channel VFCT terminal computed from STL = - (13+10log₁₀ n ), where n is the number of telegraph channels and the STL is in dBm.
