The Receive Frame Pulse Output (RFPO), when the
framing alignment is found (the OOF register bit is
logic zero), is an 8 kHz signal derived from the
receive line clock. RFPO pulses high for one RCLK
cycle every 2430 RCLK cycles (STS-3c (STM-1)).
RFPO is updated on the rising edge of RCLK.
This pin is available independently for each channel.

The Receive Alarm (RALRM) output indicates the
state of the receive framing. RALRM is low if no
receive alarms are active. RALRM is high if line AIS
(LAIS), path AIS (PAIS), line RDI (LRDI), path RDI
(PRDI), enhanced path RDI (PERDI), loss of signal
(LOS), loss of frame (LOF), out of frame (OOF),
loss of pointer (LOP), loss of cell delineation (LCD),
signal fail BER (SFBER), signal degrade BER
(SDBER), or path signal label mismatch (PSLM) is
detected in the associated channel. Each alarm can
be individually enabled using bits in the S/UNI-
QUAD Channel Alarm Control registers #1 and #2.
RALRM is updated on the rising edge of RCLK.
This pin is available independently for each channel.
