Function
RFPO
Output
AB13
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.
RALRM
Output
AB15
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), path trace identification mismatch
(TIM), path signal label mismatch (PSLM) is
detected in the channel. Each alarm can be
individually enabled using bits in the S/UNI-STAR
Channel Alarm Control registers #1 and #2.
RALRM is updated on the rising edge of RCLK.

The transmit differential clock outputs (TXC+, TXC-)
contain the 155.52 Mbit/s transmit clock.
TXC+/- must be enabled by setting the TXC_OE
register bit to logic one.
