Heynen works for innovators.



Tieline Technology is an established technology provider that manufactures the world's most advanced radio and television codecs that transmit FM quality audio, communications and data over IP and other network transports. 

Tieline codecs are the only ones in the world that are capable of sending digitally encoded audio over 3G/4G wireless networks, IP/Internet networks, standard POTS/PSTN telephone lines, ISDN, X.21, satellite (ISDN and IP) and GSM connections.

Built for today's technological requirements, Tieline Broadcast Codecs are also flexible enough to take advantage of incremental advances in technology. During the transition from circuit-switched data networks to packet-switched networks, Tieline's flexible hardware options let you connect over older technologies and upgrade into new IP technologies at your own pace.

Tieline is also playing a leading role in the development of audio over IP technologies through membership of the Audio-via-IP Experts Group. As a result, Tieline IP codecs are compatible with all major brands of codecs that have implemented the EBU N/ACIP tech 3326 specification, relating to interoperability over IP using SIP (Session Initiation Protocol).

In developing its own range of hardware and software, Tieline has assembled a strong and innovative engineering team that consults widely with customers and provides solutions that integrate seamlessly into network infrastructure.

Tieline also prides itself on delivering the support that broadcasters require and expect. Hardware and software development is supported by detailed user documentation, online and telephone support - providing a solid foundation for customers to operate and maintain Tieline equipment.
