Telos VXs User Manual

Getting callers to air has always been a bit of a challenge.

Telos was founded in 1985, and our very first product used DSP to resolve call quality issues that Bell Labs deemed impossible. The Telos 10 hybrid did what no other had done up to that point - it enabled interactions between hosts and callers that were truly broadcast quality.

Telos 10 - The first piece of broadcast equipment to use DSP, and our very first product

In the years that followed, Telos phone systems made their way into thousands of studios worldwide, connecting listeners to their favorite stations in ways that were never before possible. These digitally processed analog phone systems made caller audio sound natural.

As time and technology progressed, it became clear that calls delivered to stations digitally was the future, and Telos delivered the TWOx12 - an ISDN BRI (or POTS) based 12 line broadcast phone system. Outfitted with ISDN line cards, the connection between the telco central office and studios became digital, eliminating many of the call quality issues earlier hybrids had to resolve. Not long after, the Telos 2101 system brought this technology to scale, and made it possible for a single phone system to serve a facility with up to 4 ISDN PRIs and 32 studios.

Over time, Session Initiation Protocol (SIP) became the standard on which most commercial phone systems were based, ushering in the VoIP era in telecom. Expensive circuits gave way to solutions that are more cost effective and flexible, routable anywhere IP networks exist. With SIP, your phone system isn’t tied to a telco demarc. Calls can be routed via wired or wireless networks, even over the public internet. SIP allows us to create phone systems for broadcast with levels of backup and redundancy never before possible, and the same (or better) call quality than all technologies that preceded it.

SIP is now a mature technology. Developed in 1995, 25% of all calls were SIP by 2003. Telos saw the quickly emerging trend and unveiled the world’s first SIP based broadcast phone system, Telos VX, in 2012.

VXs is our 3rd generation SIP phone system, offering more flexibility than previous generations. While the original VX, VX Prime, VX Enterprise, and VX Prime+ required custom hardware based engines, VXs is container based and can be deployed:

• On-premises, sharing the same server hardware as other Telos containerized solutions.

• In the cloud.

• Via a hardware appliance, much like VX Enterprise and VX Prime+.

With VXs, you have the flexibility to choose the solution that best suits your needs, and the support you desire. We’re here to help with:

• Telos ProService Field Application Engineers who can work with you to take your project from concept to installed, working product.

• Worldwide partners who thoroughly understand VXs, and the entire Telos Alliance product line.
