Register Description
LATCH_ALM
0x47—Alarm 1 Status (ALM1)
ALM1 reports the current status of receive alarms. Any change in the current status activates the corresponding
interrupt status bit [ISR7; addr: 004].
Unused bits are reserved and should be written to 0.

Enable OneSec Latching of Alarms—Determines the interval for which latched active alarms
remain held in alarm interrupt status [ISR7, ISR6; addr: 004, 005].
Receive Multiframe Yellow Alarm—Real-time or integrated RMYEL status depends on the
selected framer mode and the yellow alarm integration mode [YEL_INTEG; addr: 045].
See
mode summary and
Receive Yellow Alarm—Real-time or integrated RYEL status depends on selected receive
framer mode and yellow alarm integration mode [YEL_INTEG; addr: 045]. See
for information on the parameter reported by RYEL. See
Table 8-15
Receive Alarm Indication Signal—Criteria for detection and clearance of RAIS per ITU G.775
and ANSI T1.231.
