1.6.1 'On-Hook' Operation
Figures 8a to 8c below illustrate the line signalling and FX602 I/O signals for typical 'On-Hook' (Calling Line ID)

The BT Tone Alert signal consists of simultaneous 2130Hz and 2750Hz tones. The 'Chan Seize' signal consists
of a '1010..' FSK bit sequence in all cases.
Note that the Data Retiming function is not used in these examples (RXCK is kept high).
