The Agfeo Upgrade Kit ES5xx is a module for enhancing the performance of existing telephone systems of type ES 512, ES 516, ES 522 and ES 522 IT. It serves to extend the functionality and capacity of these systems, particularly in the area of VoIP communication. The module is integrated into existing ES 5xx systems to increase their performance and activate new functions.

Applications
This upgrade kit is specifically designed for companies that wish to continue using existing ES 5xx telephone systems without compromising on extended features such as more VoIP channels, increased Voicebox capacity, or enhanced CTI functions. It is suitable for office environments where communication requirements have increased, but a complete system replacement is not economically viable. Integration is achieved without modifying the existing hardware structure, enabling quick and cost-efficient adaptation.

Functions and Equipment in Detail
The module increases the number of VoIP channels from 4 to 8, which can be used for both external and internal connections. The Voicebox recording capacity is increased from 120 to 240 minutes, allowing for longer storage of voicemail messages. Additionally, optional licenses can increase the number of AIS channels from 1 to 4 and activate the AMS function. The maximum number of TAPI lines is increased from 10 to 20, also via an optional license. These extensions enable more flexible use of the telephone system in larger or more complex networks.

Technology Explained Simply
The upgrade kit features an integrated Dual Core CPU and generously dimensioned memory, enabling simultaneous use of multiple functions such as AIS, AMS, MoH, Voicebox, Faxbox, or 3-way conferences without blocking individual VoIP channels. The hardware is designed to maintain stable system performance even under load. The expansion of IP channels and Voicebox capacity is achieved through the additional computing power and memory of the module. The use of the CTI/UC control and operation software AGFEO Dashboard is possible via an optional, cross-system license, with demo operation also supported. AGFEO Dashboard forms the basis for using VISOfon functionality, which enables PC telephony through additional license extensions.

Compatibility and Accessories
The module is specifically developed for telephone systems ES 512, ES 516, ES 522 and ES 522 IT. Compatibility with existing systems is ensured through the specific hardware and software architecture. The use of VISOfon functionality requires the installation of the AGFEO Dashboard software and additional licenses.

Installation and Mounting
Installation is performed by inserting the module into the existing ES 5xx system. The necessary steps are described in the included installation manual. The module is designed in green, visually distinguishing it from other components. A label type plate is also included in the delivery scope to facilitate identification of the module.

Operational Advantages
By expanding the IP channels and Voicebox capacity, the communication capacity of the system is significantly increased. Simultaneous use of multiple functions without performance loss ensures stable and reliable operation. The ability to activate additional functions such as AIS, AMS, or TAPI lines via licenses offers flexibility in adapting to specific business requirements. Integration into existing systems occurs without changing the network structure, simplifying maintenance and operation.

The module is finished in green. The delivery scope includes the Agfeo Upgrade Kit ES5xx, a label type plate, and an installation manual.
