Event Counters Definition
The error events monitored in the receive framer’s status registers are defined in Table 32 for the hardwired
(default) threshold values. The errored second and severely errored second threshold registers can be pro-
grammed through FRM_PR11—FRM_PR13 such that the errored and severely errored second counters function
as required by system needs. DS1 errors are reported in the ET Error registers, FRM_SR20 through FRM_SR35.
For the framer to correctly report coding and BPV errors, the LIU/Framer interface must be configured as dual rail
mode.
