Receive Channel Parity
Even/odd parity signal assigned to time-slots on RDO (bit ACR.DLC has
to be reset). Its sense is programmed via bit RC0.RPYS.
Transmit Channel Parity
Even/odd parity signal assigned to time-slots on XDI. This function is
enabled via bit XC0.EPY (bits ACR.DLC and ACR.EXMF have to be
reset). Its sense is programmed via bit XC0.EPYS.
PCM 30: Doubleframe Parity
Even parity signal of the previously received doubleframe.
PCM(+) and PCM(–) output signals which may be used for external
diagnostic loopback. The output sense is selectable via bit XC0.XTDS.
