Base stations and gateways bridge communication gaps

EFJohnson‘s 2600 Series can be configured as a repeater or as a base station in a conventional analog, Project 25 digital or mixed-mode network. When operating in mixed mode, it can detect the signaling mode of an incoming call. It then returns the call using the same protocol. The standalone 2600 supports P25 features such as group calls, emergency and System All Call. The IP25 Network Interface Unit (NIU) supports unit and talk-group validation and cross-band and cross-mode call routing across multiple sites.

C4i offers the SwitchPlus Radio Interface Unit (RIU), which uses voice-over IP to interface radios and telephony assets. The RIU supports a wide range of radio types and can stand alone as a radio-over IP (ROIP) gateway. It also can be integrated with other open-standard solutions using SIP or RTP protocols. The company also offers the SwitchPlusIP Operator Interface Unit (OIU), the communications hub of the SwitchplusIP operator position. It provides the operator with dedicated DSP audio processing resources that support a diverse range of audio equipment including mono and stereo headsets, handsets with P2T, boom mics, and monitor speakers.

Motorola‘s MOTOBRIDGE is a flexible, fixed or mobile gateway that allows public-safety radio users to connect disparate networks together for interoperability among multiple agencies. The gateway also enables radio users to be connected directly with telephone and PC users and provides advanced radio and signaling capability to ensure mission-critical performance. In addition to connecting disparate networks, the unit can be used for IP dispatch control of a single network, or as an over-IP radio voter to vote multiple receivers from the same system. The company also offers the ASTRO 25 G-series base station family, a software-definable architecture that can be configured to serve multiple purposes within an ASTRO 25 system. The G-series station supports Project 25 Phase-1 integrated voice and data.
