Audio Contribution & Distribution (Codecs)

Years ago, Telos launched the Zephyr line of ISDN codecs, one of the most popular and revolutionary products in broadcast history. 

Building upon that success, Telos Alliance continued to innovate with the Z/IP One IP Codec and the iPort Multi-Codec Gateway, both designed to function on an IP backbone. These are commercial-grade Contribution and Distribution Codecs, used by broadcasters large and small worldwide. (In fact, every professional football game broadcast on radio is backhauled to the Satellite Uplink across a Telos iPort.)

With Telos Alliance's line of Audio Contribution and Distribution Codecs, you get designed-in resiliency and reliability even with challenging connections. For example, the iPort offers packet-replacement redundancy, while the Z/IP One has 24-7-365 linking between studio and transmitter. State-wide networks can connect all their facilities using Z/IP One. Worldwide networks use iPort for both Distribution and Contribution, spanning multiple time zones.

Contact your Telos Alliance Dealer and visit our AoIP solutions page and the links on this page to learn more about why Telos Codecs are the best way to hear from there.
