Receive Multiframe/Frame Synchronization. A dual function pin to indicate
frame or multiframe synchronization. RFSYNC is an extracted 8kHz pulse, one
RCLK wide that identifies frame boundaries. RMSYNC is an extracted pulse, one
RCLK wide (elastic store disabled) or one RSYSCLK wide (elastic store enabled),
that identifies multiframe boundaries. When the receive elastic store is enabled,
the RMSYNC signal indicates the multiframe sync on the system (backplane) side
of the elastic store. In E1 mode, this pin can indicate either the CRC-4 or CAS
multiframe as determined by the RSMS2 control bit in the Receive I/O
Configuration register (RIOCR.1).
Receive Signaling. Outputs signaling bits in a PCM format. Updated on rising
edges of RCLK when the receive-side elastic store is disabled. Updated on the
rising edges of RSYSCLK when the receive-side elastic store is enabled.
Analog Loss/Receive-Signaling Freeze/Framer LOS. Analog LOS reflects the
LOS (loss of signal) detected by the LIU front-end and framer LOS is LOS
detection by the corresponding framer; the same pins can reflect receive-signaling
freeze indications. This selection can be made by settings in the Global
Transceiver Clock Control register
If framer LOS is selected, this pin can be programmed to toggle high when the
framer detects an LOS condition, or when the signaling data is frozen via either
automatic or manual intervention. The indication is used to alert downstream
equipment of the condition.
