Product Description
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 problem; optional VX interfaces break out audio into analog and digital formats, along with GPIO logic commands. And with informative 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.
Additional Information
| General | Telos 5th-generation Adaptive Digital Hybrids. Maximum number of phone lines: 48, when used with a-Law or u-Law codecs for VoIP lines. (Higher quality codecs, such as G.722, consume more system resources and result in a decreased number of total lines available.) Maximum number of SIP numbers: 250 Maximum active on-air calls: 48 Maximum number of simultaneous audio connections (Livewire+ I/O channels): 16 systemwide Maximum on-air calls on one fader: 4 |
