Explanation of the level metering function:
A signal fed to A/
μ
-Law compression via AX- and HPX-filters (from a digital loop, or externally via VIN), is
rectified, and the power is measured. If the power exceeds a certain value, loaded to XR7, bit LMR is set to
‘1’. The power of the incoming signal can be adjusted by AX-filters.

LM
Level Metering function
1)
LM = 0:
Level metering function is disabled
LM = 1:
Level metering function is enabled
LMR
Result of Level Metering function (this bit can not be written)
LMR = 0:
Level detected was lower than the reference
LMR = 1:
Level detected was higher than the reference
V+T
Add Voice signal and Tone Generator signal
V+T = 0:
Voice or Tone Generator is fed to the DAC
V+T = 1:
Voice and Tone Generator Signals are added, and fed to
the Digital to Analog Converter
