The Gateway 4 supports 4 full-duplex audio channels* in 1RU to provide two stereo connections, or one stereo and two mono connections, or up to 4 mono connections. It also supports multiple unicasting to up to 20 endpoints and multicasting.

“Tieline’s new generation Gateway codecs deliver best-in-class DSP-based reliability and performance for mission critical broadcast streaming applications,” said Charlie Gawley, VP Sales APAC/EMEA. “The Gateway 4 is designed for solutions requiring between 2 and 4 audio streaming channels, plus unrivalled redundancy features and remote configuration and control. Customers with higher channel requirements will gravitate towards the Gateway codec which supports up to 16 full duplex connections.”

For larger networks, the Gateway 4 is ideal for transmitter sites, remote trucks or rack-mounted remote kits. For affiliates and smaller stations it can be used to transport studio-to-studio links, or a stereo studio-to-transmitter link signal plus another stereo connection, or dual mono connections for remotes.

Interoperability and Redundancy

The Gateway 4 seamlessly integrates with all Tieline IP codecs and delivers hitless packet switching using SmartStream PLUS redundant streaming, plus bandwidth aggregation using Fuse-IP technologies over internet connections.

It features dual internal power supplies, dual LAN ports and dual AoIP ports. An optional Gateway Euro ISDN module can also be purchased for use with the Gateway 4. It is interoperable with all Tieline IP codecs and compatible over SIP with all EBU N/ACIP Tech 3326 and 3368 compliant codecs and devices.

The Gateway 4 is configurable through an embedded HTML5 Toolbox Web-GUI interface and is also fully controllable using Tieline’s Cloud Codec Controller.

* The Gateway 4 codec supports 4 channels only and is not upgradable to support more channels.
