Delay-Dial Trunk
G-9
After a request for service (called a seizure) is detected on an incoming trunk, the system
sends a momentary signal followed by a steady tone over the trunk. This informs the cal-
ling party that dialing can start. This type of trunk allows dialing directly into the system.
That is, the digits are received as they are dialed.
