15. 64kHz SYNCHRONIZATION INTERFACE
The 64kHz synchronization interface conforms to G.703 requirements for Centralized Timing (option A),
Contradirectional Timing, and 64kHz Appendix II. It consists of a composite clock, where a 64kHz clock
signal is generated or decoded, along with embedded frequencies of 8kHz and 400Hz. Those signals
consist of AMI code with an 8kHz bipolar violation removed at every 400Hz. There are two separate
modes referred to in the specification, one with both the 64kHz clock and the 8kHz clock, and the second
with the 64kHz clock, the 8kHz clock, and the 400Hz clock.
Figure 15-1. 64kHz Composite Clock Mode Signal Format
15.1 Receive 64kHz Synchronization Interface Operation
In the receive path, the three clock frequencies are decoded from the AMI waveform with bipolar
violations that is received at the LIU interface. The 8kHz frequency and the 400Hz frequency are decoded
from the presence or absence of bipolar violations as described in G.703.
