Technical Reference Guide
Digital PAD
Software selects A-law or Mu-Law and one of 32 possible PAD values for
each channel. These values are provided in a PROM through which the data
is routed. The idle code for A-law is 54H and for Mu-law is 7FH. The
unequipped code is FFH for both A-law and Mu-law. As the idle code and
unequipped code may be country dependent, the software instructs the
NTAK79 to use different codes for each direction. The 32 digital pads
available are illustrated below. The values shown are attenuation levels, i.e.
1.0dB is 1dB of loss and -1.0dB is 1db of gain.
