Clock Leads (pins 15, 17, 24)

Note: The Clock lead is available in OPTIMA, ULTRA, and Millennium 8000 products.

Transmit signal element timing (pin 15) and receive signal element timing (pin 17) provide timing information to the DTE. Both leads are OFF (marking state) unless &Q1-&Q3 is in effect and the modem is in the online or online command state. If &Q1-&Q3 and &X1 are in effect, the transmit clock (pin 24) from the DTE provides the transmit clock source while the modem is in the online or online command state.
