Zetron RoIP Gateway

Zetron’s RoIP (Radio-over-IP) Gateway is designed to transport analog wireline two-way radio control circuits over IP networks. Each RoIP Gateway connects to one (Model 6301) or two (Model 6302) radio circuits, and each circuit supports analog audio, binary control (PTT & COR) as well as RS232 serial data.

The analog audio is field-selectable between a balanced 4-wire connection suitable for most fixed station radios, and unbalanced transmit and receive audio suitable for direct connection to most mobile radios.

In many cases, a mobile radio’s programming and/or control head serial data can be transported over IP as well. A pair of RoIP Gateways is thus able to transport one or two analog radio circuits across an IP network.

Product features include: transports voice (3-wire unbalanced or 4-wire balanced), I/O (PTT & COR) and data (RS232) for up to two radio circuits; handles Tone Remote Control (TRC) and Local/E&M radio circuits; remote PTT operation controlled by VOX or COR; use of TCP and Unicast UDP allows operation over standard IP networks; and compatible with many IP-based RTP voice recorders.

Other features include: field-selectable voice compression includes PCM (64 Kbps) and ADPCM (16-32 Kbps); fully configurable via web browser, including all audio levels; embedded operating system, and no moving parts; designed for harsh, unattended radio site environments; optional 1U x 19″ rack mount for two units; operates from 12 VDC; optional direct, built-in support for the Department of Homeland Security (DHS).
