Multitone goes ESPA-X

The Multitone alarm server series of the i-Message 4.0 generation has been extended by the future-oriented ESPA-X network protocol.

Up to now, a standard serial data interface with the ESPA 4.4.4 protocol has been used to connect nurse call systems with DECT and personal information systems, especially in the hospital and elderly care sector. The ESPA 4.4.4 protocol was defined by the European Selective Paging Manufacturers Association (ESPA) more than 35 years ago and has been widely used as a communication protocol between solutions from different manufacturers.

In the recent past, however, the requirements for alarming have changed. Decentralized locations of remote building structures are increasingly networked via contemporary as well as structured network cabling with modern TCP/IP (Transmission Control Protocol/Internet Protocol) based network protocols and replace the old telephone copper cabling. VoIP with SIP replaces the previous ISDN telephone connections. Alarm messages are increasingly routed via alarm servers to a central location in order to centralize services.

In order to meet these new requirements, an open community of interest, the ESPA-X Community, consisting of manufacturers from different industries, has been founded to adapt the previous ESPA 4.4.4 protocol to the decentralized requirements of the future and according to today's protocol structures. Multitone is a member of the ESPA-X community of interest to promote the spread of ESPA-X. ESPA-X today stands for: "Enhanced Signaling Protocol for Alarm Processes - or Enhanced Signaling Protocol for Alarm Processes." It is an XML-based client-server architecture on the LAN interface. With ESPA-X, a flexible communication platform can be set up that enables the manufacturers of these systems to implement it in a standardized way. At the same time, the customer as user benefits from guaranteed, long-term investment security.
