Key Telephones

Key telephones have several line keys and an internal key. For incoming traffic
each line key of a key telephone is a routing destination addressed using the rel-
evant call distribution element. This means for example that calls with a different
DDI number can be offered on any line key.
For outgoing traffic each line key is linked with a separate routing. This means for
example that a specific exchange line can be used for dialling by operating a line
key.
With the internal key a key telephone can be operated like an ordinary feature-
phone.
Using Terminals as Key Telephones
The following system terminals can be configured as key telephones:
• Office 35
• Office 45
• Office 30
• Office 40
A system terminal automatically becomes a key telephone as soon as a KT line is
placed on one of the terminal's line keys.
