TRUNK PROCESSING (TP):

WINK: A signal sent between two telecommunications devices as part of a handshaking protocol. It is a momentary interruption in SF (Single Frequency) tone, indicating that the distant Central Office (CO) is ready to receive the digits that have just been dialed. In telephone switching systems, a single supervisory pulse. On a digital connection such as a T1 circuit attached to an Access Bank II, a wink is signaled by a brief change in the A and B signaling bits. On an analog line, a wink is signaled by a brief change in polarity (electrical + and -) on the line.

WINK OPERATION: A timed off-hook signal normally of 140 milliseconds, which indicates the avail- ability of an incoming register for receipt of digital information from the calling office.
