— In wink start mode, within a 128–256 ms period after receipt of the
seizure signal from the far-end, the called office transmits a 250 ms,
wink start, off hook/on hook signal to the calling office.

The far-end initiates calls as follows:
• The ground is placed on the E lead in E and M signaling.
• Dial pulses are subsequently applied from the far-end as ground open
on the E lead.
• If the far-end is equipped for sending, the system can operate in any
mode (immediate start, delay dial, or wink start), as assigned on a start
arrangement basis. See
Table 272 "Operation Mode" (page 756) .
— In immediate start mode, there is no start signal from the called
office. The seizure signal (off hook supervisory state) from the
far-end should be at least 150 ms. At the end of the seizure signal,
the far-end can start pulsing after the standard delay (normally 70
ms minimum).
— In delay dial mode, a 256–384 ms off hook/on hook signal is returned
to the far-end immediately after receipt of the seizure signal. When
the far-end detects the on hook signal (start signal), the far-end can
start pulsing after the standard delay (normally 70 ms minimum).
— In wink start mode, within a 128–256 ms period after receipt of the
seizure signal from the far-end, the called office transmits a 250 ms,
wink start, off hook/on hook signal to the calling office.
