This product supports DMR and PDT conventional standards, features digital-analog compatibility, and is equipped with rich service functions. It supports interconnection and interworking with PDT trunking, LTE trunking, PSTN systems, eChat systems and other platforms, supports docking with third-party systems through a secondary development interface, supports IP interconnection to further expand the coverage of repeaters, supports an enhanced conventional mode with richer functions and higher channel utilization efficiency, and supports digital same-frequency simulcast as well as interconnection and interworking with non-simulcast systems. In addition, the conventional repeater system based on PR900 has a simple and flexible networking architecture, is easy to construct and maintain, and delivers lower network deployment costs.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eCompact 1U design, built-in DC and AC power supplies, small footprint, enabling convenient desktop, cabinet and rack mounting. Analog-digital compatible with intelligent switching: supports both digital and analog modes, and can be configured as analog, digital or mixed mode. When set to mixed mode, the repeater dynamically switches between analog and digital modes according to the type of received calls. Leading TDMA dual-slot technology: based on advanced Time Division Multiple Access (TDMA) technology, it multiplies spectrum utilization and user capacity. The dual-slot voice output in digital mode provides two-channel calls, reducing hardware equipment costs. Broader coverage: through carefully optimized RF circuits, the reverse reception performance of the repeater is greatly improved. IP interconnection support: repeaters can be interconnected via IP ports to realize large-area, wide-range voice and data communication. Enhanced conventional and same-frequency simulcast support: with optional configurations added, it can realize advanced enhanced conventional (trunking-like call) and same-frequency simulcast functions. Rich control panel: a high-definition LCD and operation keys are arranged on the front of the device body, allowing quick and convenient configuration of the repeater. Intuitive LED indication: equipped with LED indicator lights, users can clearly and intuitively grasp the operating status of the repeater. Perfect forwarding of voice and data services: supports forwarding functions for voice and data services including telephone calls, group calls, all calls, short messages and call alerts. Remote diagnosis: supports remote (connected to the Internet via IP port) monitoring, diagnosis and control of the repeater status, improving the efficiency of system communication and maintenance. Dispatch console connection: supports connection to a dispatch console to obtain more comprehensive and professional two-way radio management services. Accessory expansion: supports third-party service development through signal flow and pin control in the rear interface. Excellent heat dissipation performance: the temperature-controlled cooling fan design ensures the stable operation of the device for a long time under 100% full power conditions.\u003c\/span\u003e\u003c\/p\u003e","brand":"Caltta","offers":[{"title":"Default Title","offer_id":49657216073984,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0840\/0034\/2272\/files\/PR900.png?v=1788228589","url":"https:\/\/www.trbow.com\/products\/caltta-narrowband-digital-repeater-pr900","provider":"Trbow Solutions","version":"1.0","type":"link"}
