Functions of the clock module on a system control board
The clock module on a system control board processes only the clock signals sent from an OSC board. When ESC is used, an STG board is used to process the clock signals. The STG board extracts the line clock signals on optical ports of service boards. Optical signals are at a specific frequency. After the optical module converts an optical signal into an electrical signal, the CDR restores the clock (high frequency) and data of the signal. The low frequency (about 8 kHz) derived by frequency dividing on the clock frequency, is the line clock.
