   Wink Start – when the originator goes off hook, the other end transmits a short (140-290ms) off-hook signal and returns to on-hook. The originator detects the wink and then sends the dialed digits. The other end goes permanently off-hook (seized) when the call is answered.

   Delay Start – the originator goes off hook, waits a pre-defined delay, and then checks for on-hook from the other end before sending the digits.

   Immediate Start – The originator goes off hook, waits 150ms and then sends the dialed digits.
