How to determine whether the clock of the PW service of the MA5635 is locked?
The MA5635 has strict requirements for the clock when the DDN and little smart services are configured. In deployment and maintenance, you can determine whether the clock is locked by performing the following operations:
1. Enable the transparent channel of the COPA board.
MA5635(su)%%transparent on 0/4
2. Check whether the clock is locked.
MA5635(su)%%dsp show pll
Running Time After locked : 65535(s)
DSP PLL State : locked
FIFO 3 Mode : Acquired
FIFO 4 Mode : Unknown
FIFO 5 Mode : Unknown
FIFO 3 Waterline : 0x00007ffb
FIFO 4 Waterline : 0x00007fed
FIFO 5 Waterline : 0x0000dda9
Output Frequency : -21 ppb
Note: In the preceding display, DSP PLL State indicates the clock state. If the time in the first line of the display exceeds 1400s and the clock is not clocked yet, it indicates that the board may be faulty or a severe packet loss occurs in the network.
3. Disable the transparent channel.
