Note: Only one function or call number can be programmed for each call key.
The following keys can be used:
■Trunk key: Calls (for the programmed call number, e.g. 11) are signalled to this key, and you can make internal and external calls via this number. A trunk key can be programmed with a substitute function (with another team member acting as the substitute). Calls for you are then signalled to the terminal of another team member. A trunk key also provides functions for managing calls. For example, you can configure call protection if you do not want to be dis- turbed, or call diversion to another telephone.
■Team key: As with a trunk key, a team key can be used to receive or make calls. However, this key cannot be used to change the settings for managing calls; it is not possible, for example, to configure call diversion to another telephone.
Calls made via a team key are signalled to all terminals with a trunk key that has been programmed with the same number. For example, the team key with the number 11 calls all trunk keys with the number 11.
■Busy key: The purpose of a busy key is to make the busy status of other sub- scribers visible. An incoming call for a busy team member is signalled on the other team member's busy key. That team member can take this call by
