A TC system can be connected to the Access system via SIP trunk or PABX gateway. TC systems without VoIP-capable network interface can be connected via analogue, ISDN or SBC gateway. Depending on the TC system, it may need to be extended in order to con- nect to the Access system: • Hardware: (e.g. retrofitting VoIP assemblies/PCBs) • Software/software licences: (e.g. system update and additional licences from the TC manufacturer)These extensions are not part of the scope of supply of the Access system and must not be confused with the user and application licenses which are needed for the operation of the Access system.16
