Function
Receive Channel Parity
Even/odd parity signal which supplements the
number of ones of a received channel to an even/
odd quantity while sending channel data to output
RDO. The parity type is programmed by bit
RC0.RPYS.
PCM 24: Additional Function Receive
If enabled via bit ACR.DLC, this output provides a
4-kHz signal which marks the DL-bit position
within the data stream on RDO. It can be used as
receive strobe signal for external data link
controllers.
Receive Frame Synchronous Pulse (active low)
Framing pulse derived from the received PCM
route signal. During loss of synchronization (bit
RSR.LOS), this pulse is suppressed (not
influenced during alarm simulation).
Pulse frequency: 8 kHz
Pulse width:
11
488 ns [PCM 30]
648 ns [PCM 24]
