Framer Register Architecture
The following registers are dedicated to the exchange termination and its remote end interface. The alarm condi-
tions to trigger errored seconds and severely errored seconds are defined in Table 32 and the ET and ET-RE
enable registers, FRM_PR14 and FRM_PR15. The thresholds are defined in registers FRM_PR11—FRM_PR13.

ET Errored Second. A 1 indicates the receive framer detected an errored second at the
exchange termination (ET).
ET Bursty Errored Second. A 1 indicates the receive framer detected a bursty errored
second at the ET.
ET Severely Errored Second. A 1 indicates the receive framer detected a severely
errored second at the ET.
ET Unavailable State. A 1 indicates the receive framer has detected at least ten con-
secutive severely errored seconds. Upon detecting ten consecutive nonseverely errored
seconds, the receive framer will clear this bit. ITU Recommendation G.826 is used
resulting in a ten-second delay in the reporting of this condition.
ET-RE Errored Second. A 1 indicates the receive framer detected an errored second at
the exchange termination remote end (ET-RE).
ET-RE Bursty Errored Second. A 1 indicates the receive framer detected a bursty
errored second at the ET-RE.
ET-RE Severely Errored Second. A 1 indicates the receive framer detected a severely
errored second at the ET-RE.
ET-RE Unavailable State. A 1 indicates the receive framer has detected at least ten
consecutive severely errored seconds. Upon detecting ten consecutive nonseverely
errored seconds, the receive framer will clear this bit. ITU Recommendation G.826 is
used resulting in a ten-second delay in the reporting of this condition.
