Raytheon's JPS Communications introduces its new Analog Radio Adapter, the ARA-1. Comparable to an analog telephone adapter (ATA), which allows a standard telephone to operate on a session initiation protocol (SIP) network; the ARA-1 provides the same functionality to radios.

"The ARA-1 is a perfect marriage between land mobile radios and IP-based networks," states Mike Cox, vice president of engineering for JPS Communications. "It combines a supremely capable radio interface to the standards-based open SIP protocol that is rapidly becoming the acknowledged pathway to the convergence of voice, data and video."

ARA-1 Case Study
Alberta's Shock Trauma Air Rescue Society (STARS) has improved its emergency communications at its new Grande Prairie base by deploying Raytheon JPS Communications' new ARA-1. Using the ARA-1, an interoperability device that provides an interface between a radio and an IP-based network using SIP, STARS communications specialists can now communicate in a more timely and efficient manner.

Need to communicate where your SIP telephone can't?
The addition of radio interface capability using the ARA-1 not only brings existing radio networks into the SIP arena but also allows SIP-based communications to be extended into areas that are not serviced or cannot be reached using a SIP network. For example, an ARA-1 can be used with an LMR system to extend the SIP network into areas of rugged terrain, across bodies of water, or into tunnels.

Need IP-addressable radios?
With the ARA-1, IP-addressable radio interoperability is now available in the SIP environment. The ARA-1 provides to radio networks all of the features available with SIP. These include interoperable communications among disparate radio systems that is as easy as creating a typical PBX conference call and other PBX features such as Call Logging, Call Forwarding, and Call Recording.

The radio side of the interfaces makes full use of the broad suite of digital signal processor algorithms, hundreds of interface cables and numerous problem solving techniques that JPS has evolved during more than a decade as the market leader in radio interoperability.

SIP & Mobility: Bringing Radio into the 21st Century
The adoption of SIP in the mainstream telephony world has numerous and proven benefits: open standards, a rich feature set, and readily available equipment from multiple vendors. Now SIP brings all of these benefits to land mobile radio (LMR) users plus entirely new interfacing and interoperability options. This article explores how to interface radio equipment with SIP infrastructure and explains the features radio users can expect to enjoy. To read the full article, please click here.

Why SIP?
The main goals of modern communications system design include: convergence of voice, data and video; standards-based open protocols; and individual IP addresses for all end-devices. SIP is widely seen as the preferred pathway to achieving them.

ARA-1 Benefits/Features:

• Radio-to-SIP interfaces brings radio to SIP networks or SIP to radio networks.


• Interoperability is as simple as creating a conference call within a SIP PBX.


• Brings SIP PBX features into a radio arena - including call logging, forwarding and recording.


• Extends SIP-based communications to rugged terrain areas.


• Enables communications between radios and network communications devices such as SIP phones and softphones.


• Applicable to a wide range of network topologies.


• Supports making calls both with and without a proxy server.


• Supports operations behind a NAT firewall.
