10. CROSS CONNECTIONS FOR DIGITAL INTERFACES
Perform the cross connections for digital interfaces as shown below:
Note 1:When your system is single IMG configuration, time division switch (TSW) card is equipped with Phase
Lock Oscillator (PLO). Therefore no dedicated PLO card is required to use Digital Interfaces. However,
when the system requires a higher-precision oscillator, use the Oscillator (OSC: PA-CK14) card. The cards
may be...
