When IDAS dPMR radios are connected to a PC or other external equipment, the IDAS dPMR transparent data mode provides up to 3, 600 bps data communication in a 6. 25kHz channel. Up to 16 IDASTM dPMRTM repeater connection With the optional UC-FR5000 (#12 version required), up to 16 IDAS dPMR repeaters can be interlinked over an IP network to extend your communication coverage. CACHET REVENDEUR VHF DIGITAL/ANALOGUE REPEATER UHF DIGITAL/ANALOGUE REPEATER dPMRTM Introduction and History dPMR stands for "digital Private Mobile Radio" and it is an open standard digital radio protocol published by the European Telecommunications Standards Institute (ETSI). dPMR utilizes 6. 25kHz narrowband FDMA technology with the AMBE+2TM voice codec that offers many forms of voice and data applications. The dPMR standard (TS 102 658) has three operating modes: Mode 1 Direct peer-to-peer mode Mode 2 Conventional repeater mode Mode 3 Centralized trunked network mode VHF DIGITAL/ANALOGUE TRANSCEIVERS UHF DIGITAL/ANALOGUE TRANSCEIVERS Features · Frequency coverage: 136­174MHz, 400­470MHz · Compatibility with dPMR mode 1/2 · IDAS dPMR and analog FM mixed mode operations · 512 memory channels with 128 zones · Dot matrix, multi-function LCD · Large capacity Lithium-Ion battery pack · Dust-protection and waterjet resistance equivalent to IP55 HM-170GP GPS Speaker-microphone Options IDAS dPMR products support basic conventional Mode 1 and Mode 2 operation at this stage.

(Left side is an option. ) dPMRTM MoU (Memorandum of Understanding) Group The dPMR standard is delivered by the initial responsibility of the dPMR MoU group under the mandate of ETSI. The dPMR MoU group selected the standard vocoder and will perform interoperability and conformance testing using ETSI standards. [. . . ] The dPMR MoU group selected the standard vocoder and will perform interoperability and conformance testing using ETSI standards. Through the evaluation testing, dPMR equipments will interoperate with each other, ensuring longevity of the system and a good return on investment. T Series (10-Keypad Version) S Series (Simple Keypad Version) UT-124R Man Down Unit Communication link for distant locations An IDAS dPMR IP network can extend your communication coverage and allows you to communicate like a single site. It lets you connect dispersed sites or different bands over the IP network. [. . . ]
