standard telegraph level (STL)

The power per individual telegraph channel required to yield the standard composite data level. Note: 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.
