A phone that can only call a single destinaiton. When the phone receiver is off hook, the station automatically dials the destination.
Then you would program an analog set. (This really only works for analog stations.) On page 3, you'll find entries for a hotline destination. Put in the abbreviated dial list and member you would like to have that station call, and then make sure there is a phone number programmed in that list.
So if you put 'system" list in the List1 location, and member 20 of list 1 as the hotline destination, just put a phone number in member 20 of the system abbreviated dial list.
Anytime someone picks up that phone, it will call that number. No dialing necessary.
Be sure to turn off hookswitch flash. It tends to make things messy. You'll want each pickup to launch a new call, and each hangup to end the previous call attempt.
If you mean: Like a private broker line to the outside world (us old timers called them ARD's) the telco would drop off the circuit and tell the tech the type of circuit it was Manual or automatic. Manual circuits were defined as personal co lines and a siginal button. Automatic were assigned as trunks with the incoming destation assigned to a number on the set. The trunk group was translated as a two way immed/immed. The telco circuit was crossconnected to a tie trunk card and the tie trunk ELL was placed as the only member of the trunk group. As soon as the far end picked up the near end set would ring. On the near end you have to use TAC (Trunk Access Codes) to select and complete the calls.
