The system can operate in either of two modes; PBX or Key. The selected mode affects the system's outgoing call routing and incoming call routing settings.
The default setting for the system's Mode is determined by the type of SD card installed in the system.
•IP Office U-Law SD Card
A system fitted with this type of card defaults to U-Law telephony and IP Office Basic Edition Key System operation. Intended for North American locales.
•IP Office A-Law SD Card
A system fitted with this type of card defaults to A-Law telephony and IP Office Basic Edition PBX System operation. Intended for locales outside North America.

•In addition, any existing button programming is removed and all buttons are defaulted according to the requirements of the selected mode.

The Number of Lines setting is used to automatically assign line appearance buttons on all extensions with programmable buttons. To make external calls the user should select an available line appearance button. Outbound call routing is determined by which line appearance button the user selects before dialing or by the user's automatic line selection settings.
No line appearances are automatically assigned to programmable buttons. The Outside Line setting is used to set the dialing prefix that indicates that the call is an external one for which an available line should be seized. The Alternate Route Selection settings are used to determine which lines are used for each outgoing call. Line appearance buttons can also still be configured for making and answering external calls.
