1. The off-hook counter and calibrations prevent transmission or reception of data for 402.75 ms (default) for the line
2. The caller alert signal (CAS) tone transmits from the CO to signal an incoming call.
3. The device is taken on-hook to read the line voltage in the LVS bits to detect parallel handsets. In this mode, no data
4. When the device returns off-hook, the normal off-hook counter is reduced to 8 ms. If the CALD and RCALD bits are
5. After allowing the off-hook counter to expire (8 ms), normal transmission and reception can continue. If CID data

this. To use the OFHK pin instead of the OH bit, simply enable the OHE bit (Register 5, bit 1) and drive the OFHK pin
low during the preceding sequence. This has the same effect as setting the OH bit.
