Each DuSLIC channel has a three-party conferencing facility implemented which consist
of four PCM registers, adders and gain stages in the microprogram and the
corresponding control registers (see
This facility is available in PCM/ C mode only. The PCM control registers PCMR1
through PCMR4 and PCMX1 through PCMX4 control the timeslot assignment and PCM
highway selection, while the bits PCMX-EN, CONF-EN and CONFX-EN in the BCR3
register control the behavior of the conferencing facility and the PCM line drivers (see
