Bit Name
Default
Bit No.
This bit decides whether the received data should pass through or bypass the Receive Jitter Attenuation FIFO.
= 0: The received data passes through the RJAT FIFO.
= 1: The RJAT FIFO is bypassed. The delay is reduced by typically 24 bits.
= 0: The Frame Processor operates normally.
= 1: Frame searching is disabled, the RCRB holds its signaling frozen, and Auto_OOF function, if enabled, will consider OOF to be declared.
This bit is valid in framed mode.
= 0: Compare the inband loopback activate/deactivate code with all received data stream, including the F-bit. However, the result of F-bit compar-
= 1: Compare the inband loopback activate/deactivate code with the received data stream, excluding the F-bit.
This bit decides whether to send the Yellow Alarm signal automatically.
= 0: The automatic Yellow Alarm Transmission is disabled. It means that the Yellow Alarm can only be transmitted when the XYEL (b1, T1/J1-
= 1: The automatic Yellow Alarm Transmission is enabled. It means that the Yellow Alarm will be transmitted automatically when Red alarm is
This bit decides whether to start trunk conditioning (replacing data on RSDn/MRSD with the data stored in the data trunk conditioning registers in
= 0: The trunk conditioning is not activated automatically when Red Alarm is declared in the Alarm Detector block.
= 1: The trunk conditioning will be initiated automatically when Red Alarm is declared in the Alarm Detector block.
This bit decides whether to start trunk conditioning (replacing data on RSDn/MRSD with the data stored in the data trunk conditioning registers in
= 0: The trunk conditioning is not activated automatically when the INFR (b0, T1/J1-022H) is declared in the Frame Processor block.
= 1: The trunk conditioning will be activated automatically when the INFR (b0, T1/J1-022H) is declared in the Frame Processor block.
This bit decides whether the PMON and PRGD registers are automatically updated once every second.
= 0: The PMON and PRGD registers are not automatically updated. They can only be updated by MCU operation.
= 1: The PMON and PRGD registers will be automatically updated once every second.
