Team Functions
On the other telephones in the team, this call number is programmed as a team
key (e.g. TK 10 on Johnson's and Smith's telephones). The team members can thus
see which number a call is for and can answer it by pressing the appropriate team
key.
The team members can call each other via the team keys. For example, Miller can
call number 12 by pressing TK 12; the call is then signalled to Smith's telephone on
TrK 12.

Line Busy Indication
If a line is busy, e.g. TrK 11 Johnson, the team keys 11 on Miller's and Smith's tele-
phones will indicate this.
Call Signalling
In this example, calls via the trunk keys are signalled acoustically. Calls via the team
keys are indicated by a visual signal (the team key LED flashes).
