COMfortel® XT-PS

Plug-in power supply for the power supply of the key expansion module COMfortel® Xtension300

If the corresponding COMfortel system telephone on which a COMfortel Xtension 300 keyboard extension is to be operated is supplied via the system connection (ISDN bus or PoE), the optionally available COMfortel XT-PS power supply unit is required to operate the extension (exception: COMfortel 2600 IP). This power supply unit supplies all connected expansion modules. The power supply unit is required in any case from the second module.
