15.2 Transmit 64kHz Synchronization Interface Operation
In the transmit path, the framer generateS the appropriate AMI waveform with the correct bipolar
violations as described by G.703 and GR.378. If an 8kHz signal is present on the TS_8K_4 pin, the
bipolar violations are generated synchronously with this signal. If it is absent, the part arbitrarily
generates the bipolar violation at an 8kHz frequency.
