Telos VX Broadcast VoIP Telefoon Hybride System

VX is the world's first VoIP (Voice over IP) talkshow system -- a broadcast phone system that's so powerful it can run all of the on-air phones for your entire plant, but economical enough for stations with just two or three studios. VX connects to traditional POTS and ISDN telephone lines via standard Telco gateways. But it also connects to VoIP-based PBX systems and SIP Trunking services to take advantage of low-cost Internet-delivered phone services.
VX also weds modern networking to the remarkable power of digital signal processing. VX uses Ethernet as its connection backbone, significantly cutting the cost of phone system installation, maintenance and cabling.Ethernet is a powerful, yet simple way to share phone lines among studios and connect system components.This also makes VX naturally scalable, capable of serving even the largest of facilities -- while remaining surprisingly cost-effective for even single stations with more modest needs.
VX plugs right into Axia IP-Audio networks, connecting multiple channels of audio and control via a single CAT-5 cable. Don't have an IP-Audio network yet? No problemoptional VX interfaces break out audio into analog and digital formats, along with GPIO logic commands.And with informative new VSet phones, talent finds it easier than ever to take control of their callers, moving and sharing lines between studios at the touch of a button.
Why VoIP for Broadcast?
VoIP has taken the business world by storm, increasing the flexibility of office phone systems and PBXs while simultaneously lowering maintenance and equipment costs. In fact, most Fortune 500 companies have replaced their older PBX systems with VoIP for just these reasons.
VoIP is a natural for broadcasters, interconnecting the phone system CPU with audio interfaces, phone sets, console controllers, and PCs running screening software by way of efficient, low-cost Ethernet. Using VoIP, you can finally share phone lines among multiple studios and route caller audio anywhere in your facility, easily and instantly. Got a hot talkshow that suddenly needs more lines in a certain studio? Just a few keystrokes at a computer and you're ready -- no delays, and no cables to pull. VX can even connect with your business office's VoIP PBX to allow easy call transfers.
But it's not just VoIP - It's VoIP from Telos. Every incoming line has its own fifth-generation Telos Adaptive Digital Hybrid, our most advanced ever - packed full of technology engineered to extract the cleanest, clearest caller audio from just about any phone line, even notoriously noisy cellular calls. Multiple lines can be conferenced with superior clarity and fidelity. Smart AGC ensures consistent caller audio levels. New Acoustic Echo Cancellation from FhG removes feedback and echo in open-speaker studio situations. And should you choose to use SIP Trunking telco services, calls from mobile handsets with SIP clients will benefit from VX's native support of the G.722 codec, instantly improving caller speech quality.
VX System Components
The VX Engine, afan-free 2RU rack-mount device with enormous processing power, is the heart of the system. It provides all the call control and audio processing needed for the system, and supports up to 30 active calls on-air simultaneously, across as many as 20 studios. VX configuration is Web-basedany Web browser can be used for remote control and configuration.
The VX Engine's DSP platform is so powerful, it provides a hybrid for every line, allowing multiple calls to be aired simultaneously with excellent quality, no matter what kind of line or phone the caller is using. Smart AGC coupled with Telos three-band adaptive Digital Dynamic EQ and a three-band adaptive spectral processor are part of the toolkit send audio gets a frequency shifter, AGC/limiter and FhG's Advanced Echo Cancellation technology to eliminate open-mic feedback. Call ducking and host override round out the package.
The VX Engine works with standard telco gateways from Patton, Cisco, Grandstream and others for traditional phone services, like T1/E1, ISDN, and POTS. For VoIP-based PBX or SIP Trunking telco service, VX uses standard SIP (Session Initiation Protocol) and RTP (Real-time Transport Protocol).

The VSet12 phone controller is an IP-based phoneset with two large, high-contrast color LCD panels that provide line status and caller information using easy-to-understand Status Symbols. Use them like a traditional Telos controller to select, hold and drop calls, or use them to map phone lines to individual faders for greater control - even assign a group of lines to a single fader. Additional controls lock calls on-air, start external recording devices, and queue calls for sequential airing. A built-in address book and call history log, detailed line status, caller information, caller ID, time ringing-in or on-hold, and screener comments all help ensure error-free production of fast-paced shows.

The VSet6 phone controller is a six-line version of the VSet12. Like its big brother, it has a large color screen with animated Status Symbol icons, and controls for 6 phone lines. With all the control functions of the VSet12, it's great for smaller or secondary studios.

The VSet1 phone controller is a single-line phoneset for news booths, voiceover stations, etc., where access to just a single line is needed.

Console Controllers: Live calls or pre-recorded, interviews or audience participation, one thing's certain: phone segments are an integral part of today's fast-paced radio. Wouldn't it be great if talent could take control of phones without ever having to take their focus from the board?
They can: VX connects directly to Axia mixing consoles using Livewire IP-Audio to eliminate the cost and complexity of old-style inputs, outputs, and mix-minuses. IP-Audio consoles with built-in phone controllers don't need any additional wiring: control signaling, caller audio and backfeeds ride on the network connection that's already there.Integration helps shows run smoother, since phone controls are right in front of talent, in the console. And since the console now communicates directly with the phone hybrid, mundane tasks such as mix-minus generation, recording device activation and playback of pre-recorded conversations can all be automated, allowing talent to focus on doing what they do best - their show.
VX Audio & Logic Interfaces let you connect VX to any non-networked radio console or other broadcast equipment, using standard analog or AES/EBU interfaces. A GPIO Logic interface provides control logic where needed.
VX System Configuration
Telos VX is a "facility wide" on-air telephone system: multiple studios, multiple stations, multiple shows can all be managed by a single system, with minimal hardware requirements. VX rids you of the maze of discrete cables once required by a multi-line talkshow systemcomponents are linked with standard Ethernet. A single CAT-5 cable hosts connections to the telco interface, line switching commands, data communication between the Vx Engine and VSet phones, transport of caller audio to mixing consoles, return of mix-minus and program-on-hold audio to the caller, data messages (such as call notes and IM) between producer and talent, Livewire audio call recording, and transfer of recorded call files from the producer to the studio.
Telco is delivered via IP through a POTS, ISDN or T1 gateway device, a SIP PBX, or a dedicated IP circuit using SIP Trunking. Got an Axia Livewire AoIP studio network? Telos VX plugs right in. Audio inputs and outputs are Livewire real-time audio channels, traveling over your existing Axia system just like the rest of your audio. Axia console GPIO ports can be used for "phone ringing" tallies or remote control of profanity delay units from 25-Seven Systems (or others). It's the seamless integration of studio phones, mixing consoles and routing network you've dreamed about! This diagram shows just how easy it is to combine VX with your Axia network.
Don't have IP-Audio networking yet? VX works with all console brands, networked or not, via VX Audio and Logic interfaces - compact 1RU breakouts that put multiple I/O channels right where you need them. This diagram shows a typical studio with an analog mixer, using VX Analog and GPIO logic interfaces to connect to the console and other broadcast equipment.
