Longitudinal Reference. VLBIAS is programmed by VOFF and supplies the longitudinal
reference voltage for the longitudinal control loop to the ASLIC device.
12/16 kHz Metering Signal. For 12/16 kHz teletax, an internally generated and shaped 12
or 16 kHz sine wave metering pulse is output from this pin.
Analog Output. The voice data from the received PCM channel (timeslot) is digitally pro-
cessed and converted to an analog signal which is present on the VOUT pin of the
ASLAC device.
Analog Reference. This pin provides a voltage reference to be used as the analog zero
