AC, DC: Power indicator. ON indicates normal work. NOP: Indicator for no optical alarm. OOF: Indicator for out of frame alarm. LOS: Indicator for losing E1 signal alarm. ON indicates local E1 signal loss.
Flicker indicates remote E1 signal loss. AIS: Indicator for E1 interface alarm. ON indicates that all the signals input to local E1 interface are "1". Flicker indicates all the signals input to remote E1 interface are "1".
TEST: ON or flicking indicates optical circuit in testing (SEL:6=ON). The indicator keeps ON when loop by DIP switch, and flicking indicates loop by cable. Please note: the optical circuit in testing must be in loop status. The common method is connecting E1 input and output of remote device directly.
OK: ON indicates the above test is in normal while OFF indicates abnormal.
CONSOLE: network management and RS232 data interface. Please check below appendix A for details.
