7. Radio interfaces l RS232 serial interfaces – for digital radio stations connection – TETRA or TETRAPOL radio stations l TETRA interface – pins for Tx Audio, Rx Audio, GND, RTS (RS232), CTS (RS232), Tx (RS232), Rx (RS232) l TETRAPOL interface – pins for Tx Audio, GND, Rx (RS232), Rx Audio, Tx (RS232) l RS232 serial interfaces – for analogue radio stations connection l Analogue interface – pins for PTT, CD, GND, Rx – audio, Tx – audio & 3 pins for channel steering l E&M analogue interfaces – for analogue radio stations connection l 4 wires analogue interfaces – Rx, Tx, PTT & Squelch l E&M signaling types I, II, III, IV, V – hardware configuration

8. Main features l Individual private call, half duplex l Full duplex on private calls for TETRA l Group call, half duplex l Group monitoring (sequential scanning), half duplex l Emergency incoming group call, half duplex l PTT sent/receive to/from the IP network through SIP info messages l Receive (Rx), Transmit (Tx), PTT and SQUELCH detection l Monitor for each radio station

9. Configuration tools l Local and remote configuration available l OAM application – Operation, Administration and Maintenance software which can be accessed via Ethernet or serial RS232 interface l SSH – to edit configuration text files l Secured access for administration and configuration – password protected l Several access levels defined for administrator, user with corresponding rights l SNMP monitoring l Telnet configuration

10. OAM application l Allows add/remove radio boards in the equipment – analogue or digital – TETRA and TETRAPOL l Define active channels for analogue radio stations l Defining time intervals for scanning radio channels l Defining time intervals for locking radio channels l Allows defining groups of radio stations - when activity is detected on a channel belonging to a group of channels - the application will not transmit on any other channel which belongs to the same group

11. Reports and statistics l Detailed reports and statistics related to the calls passed through the radio gateway equipment l Status monitoring for ports – open, available, in alarm, invalid position l Status monitoring for cards – installed card, open line, in alarm position l Several parameters related to calls details such as IP source, destination ports, start and end time of the calls, call duration l Alarms available in case of hardware and software errors

12. 112 Emergency System l TOPEX IP Radio Gateway integrated in Romanian 112 Emergency System l Interconnection with Ericsson Coordcom entity l The communication between Ericsson Coordcom and TETRA radio stations is made through TOPEX Radio Gateway solution l TOPEX Radio Gateway configuration is loaded into Coordcom solution via SIP OPTIONS messages l TETRA services like private calls, group calls and monitoring are implemented via standard SIP sessions l Each radio gateway has an unique ID defined in the commanding system

13. Benefits l Improved control with more efficient communications and accurate dispatch l Enhanced response to incident through complete range of communications l Interconnection with all types of radio networks l Easy integration with Mission Critical Application systems l User friendly Graphical User Interface for maintenance and configuration l High quality of information and voice quality
