E1 X Clock. This clock signal is used to generate E1 AIS
(all 1s). It must be 2.048 MHz ± 50 ppm, or x16, x32 of
2.048 MHz.
DS1 X Clock. This clock signal is used to generate DS1
AIS (all 1s). It must be 1.544 MHz ± 32 ppm, or x16, x32 of
1.544 MHz.
DS2 AIS Clock. A 6.312 MHz ± 30 ppm clock input used as
DS2 AIS clock or DS2 data output clock.
VC11 AIS Clock. A 1.664 MHz input. In the VTMPR mode,
this clock is used to generate VC11 AIS.
E2 AIS Clock. A 8.448 MHz ± 30 ppm clock input used as
E2 AIS clock or E2 data output clock.
VC12 AIS Clock. A 2.224 MHz input. In the VTMPR mode,
this clock is used to generate VC12 AIS.
DS3 X Clock. A 44.736 MHz ± 20 ppm clock input for DS3
DJA.
E3 X Clock. A 34.768 MHz ± 20 ppm clock input for E3
DJA.
