ZURICH, SWITZERLAND, September 1, 2010 — Barix AG, a pioneer in IP-based audio, intercom, control, and monitoring, continues to innovate for the radio broadcast industry.  The company will showcase its latest hardware and device firmware at IBC 2010 (Booth 8.B16, RAI Exhibition Center, Amsterdam, September 10-14), giving broadcasters more options in the way they use Barix for delivery of program audio between studios and transmission points.

Now shipping, Barix will display its Exstreamer 500 IP audio decoder to international audiences for the first time at IBC.  The Exstreamer 500 is a professional Audio over IP hardware device designed specifically for radio broadcasters, offering a one-half, 19-inch rack mount solution with encoding and decoding capability.  It is essentially a lower-cost version of its high-end device, the Exstreamer 1000, while retaining important features like balanced inputs and outputs and contact closure interfaces.  Broadcasters can purchase the Exstreamer 500 through the Barix global network of established broadcast distributors, accessible at www.barix.com.

Barix will also introduce new easy-to-configure device firmware that provides more technical options and functionality for program audio transport.  The new “STL software package,” pre-loaded onto new 500 and 1000 devices, is also available as a free update at the Barix website and can be loaded onto all existing Barix Instreamer encoders and Exstreamer decoders.  This enables new features including full-duplex audio transport (48kHz sample rate PCM, full-duplex devices only) and trap-based alarming, while reducing external hardware requirements previous necessary for such enhancements.

“The new universal, feature-filled Barix software is a fully configurable application that fits well into many different scenarios a broadcaster may have for program audio transport, such as directed or unidirectional microwave-carried IP, remote contribution, and internet-based low-bandwidth applications,” said Johannes G. Rietschel, CEO and Founder of Barix AG.  “Through manual fine-tuning of the software, we offer many of the professional features that broadcasters rely on for high-quality audio transport between locations.  This, along with quick set-up, is especially ideal for Exstreamer 1000 users that want more freedom to configure various options onto their devices.”

Barix has included the Reflector Service client on the same software load.  This previously announced service simplifies connections for broadcasters via a plug-and-play scenario.  The Reflector Service completely removes any need for user configuration:  The hosted application serves as an online center to configure and monitor the audio transport bridge while also providing a straightforward relay of the audio feed, enabling almost immediate audio streaming between two devices.  Users of the STL software package can switch between the new STL software (the default on Exstreamer 1000) and the Reflector client (default on Exstreamer 500) via web browser.

All Barix products are inexpensive, low-power devices that are scalable to the growth of the operation; offer high reliability through a PC-FREE design with no moving parts; and serve as a flexible platform for integration into virtually any operation requiring audio transport and delivery over IP networks.   Barix also offers its programmable BCL standard open to all customers to easily customize applications for specific needs.  Local control, audio relay, and low-latency streaming are a few examples of custom programs using Barix’ BCL software environment.

ZURICH, SWITZERLAND, August 24, 2010 — Barix AG, a pioneer in IP-based audio transmission, intercom, control and monitoring systems, introduces the Annuncicom 155 IP intercom and announcement device developed foremost for use on trains and in rail stations and tunnels.

The device, to be introduced at the Innotrans rail transportation show in Germany (Messe Berlin Exhibition Centre, September 21–24, Hall 4.1, Stand 216), enables systems integrators to set up tailored communication systems ranging from simple door intercom, PA and background music systems to complex monitoring functions and emergency announcement systems.  It is also the first Barix device to meet EN50155 standard requirements for rail vehicle installations.  (“Railways Applications Electronic Equipment Used on Rolling Stock.”)

The basic principle of an Annuncicom 155 communication system is both elaborate and simple.  At least two devices are connected to a standard TCP/IP LAN network to exchange live announcements as well as priority, monitoring and control information for a standalone system.  Barix SIP firmware can enable integration into conventional SIP-based telephone systems.  Control signals and a serial port allow the connection of a selector switch, buttons or display.  This allows for destination selection and the control and display of connection status.

The Annuncicom 155 system can operate as a standalone system or in conjunction with PCs and central IT management in a standard network, enabling low-cost and quick configuration of the communication system while guaranteeing future expansion.

“As with all Barix products, the Annuncicom 155 is based on standard TCP/IP and works with Audio-over-IP.  This means it can be integrated very easily and conveniently into existing networks, and allows for wide-range networking and deployment – even in Multicast mode to simultaneously address any number of subscribers,” said Johannes G. Rietschel, CEO and Founder of Barix AG.  “Its stable design is perfectly suitable for harsh everyday operation in trains, buses and ships, as well as for deployment in general applications under harsh environments, including transport and industrial.”

The Annuncicom 155 conforms to the usual transportation standards including EN50121 and EN50155.  Devices without EN50155 conformity are typically not used in trains, carriages and other rolling stock for railways.

“The requirements for such devices are quite demanding, and we are happy to offer the first Barix product to the rail transportation industry that meets requirements for on-board use,” said Rietschel.

But .. how do you connect a door intercom or door station to them ?

Fortunately, the latest SIP firmware for the Annuncicom makes a perfect companion for the Siemens Gigaset IP phones, it can talk with the Siemens phone via IP !

• A visitor, who presses the “ring” button on the phone, places a SIP call to the Siemens base. This can be done “peer-to-peer”, so it won’t consume an account entry, and it does not need a PBX or server to work.

• The DECT phones will ring, indicating a call from the IP address of the Annuncicom

• The user can answer the phone talk to the person in front of the door, and also open the door by typing a configurable number sequence on the keypad (for example, “11″).

• Even multiple Annuncicoms can be used in this fashion, for example, for front door and back door !

The solution works, of course, also with other SIP PBXes like Asterisk, but the beauty with the Siemens IP phones is that there is no servers, no PBX, only little configuration needed.

Barix developed a “Multicast routing/tunneling” firmware for the Barionet which turns that device into a flexible, multi site multicast forwarder/router. Effectively, it bridges multiple multicast groups between multiple sites, and can also include single hosts. The functionality is independent on the actual protocols used with the Multicast, being it automation, IP Audio, Video, VoIP, SIP or RTP.

Here is the rough concept:

• A Barionet is installed in every subnet where multicast traffic needs to be pickeed up or delivered.
• The device(s) does “UDP” tunnelling to forward the Multicast packets to the other Barionet(s) in the other subnet(s). At the same time, they serve as a tunnel receiver/endpoint to receive encapsulated Multicasts from the other networks.
• Up to 8 independent multicasts (address/port) can be configured, and up to 8 destinations – either Barionets in other networks as tunnel endpoints, or hosts which then receive the packets unicast.
• The TTL field of the multicast blocks can be “ignored and set to configured value” or handled as usual (decrementing).
• Tunnelling can be configured to use “IP over IP” or plain UDP – both have advantages and disadvantages.
• Monitoring of the application is possible via SNMP.

The first customer uses the application to route VoIP/VHF radio traffic between multiple operations centers in a large company. However, applications can be found wherever multicast needs to be routed between subnets and routers, IT providers or policies prevent that.

Please contact Barix if you are interested in that solution!

the Barionet, the IP Automation device from Barix, would tweet ?

This is quite simple to achieve. We have sample BCL code, which allows you to do just that. Being it contact closures or temp sensors, these can be monitored, and in case of out-of bound data, the Barionet can directly talk to the twitter servers and “tweet” an alarm message.

Contact us for the source code (and beware, it’s sample code ..)

If you want to read about the Reflector, what it does – how it works, please check it out here: www.barixreflector.com. In an essence, it allows you to use UNCONFIGURED – zero config – devices  on both ends of a “virtual audio cable over the internet”. You just log into the website, open a project, list the devices you want to use, do trivial feature selection, plug the devices on at two ends of the internet, anywhere (as long as the devices can get OUT to the internet) .. and audio magically streams !
