6 Message Reference
— Bit 15 is set to 1 for diagnostics purposes to cause the results of board configuration to be passed to
the host. When set, all confirmation messages generated internally on the board during the
configuration sequence are sent to the 0xdf module ID on the host.
— All other bits are reserved for future use and should be set to 0.
• l1_flags
Level 1 flags with the following bit significance:
— Bit 0 controls the layer 1 clock reference source. If set to 0, the clock is recovered from the onboard
oscillator. If set to 1, the clock is recovered from one of the line interfaces. Line interfaces can be
individually configured with the LIU_MSG_CONFIG message to explicitly be excluded from recovering
the clock from the interface.
— All other bits are reserved and should be set to 0.
