Table 17. Internal Clock Selection of Equipment
The internal clock is obtained from the crystal oscillator from itself, with ±25ppm precision.
The regenerate clock is obtained through the line G.shdsl signal, having the same precision of the
equipment providing the signal. When operating with regenerated clock, the modem automatically
switches to internal clock in case of flaw in the G.shdsl signal in its input. When configured as LTU, the
modem can not be configured with regenerated clock.
