Tieline Introduces Gateway-4

by RedTech Staff February 17, 2021 3 min read
 Tieline Introduces Gateway-4
Print Friendly, PDF & Email

Tieline has added the Gateway-4 IP audio codec to its range of professional IP audio codecs.

The company describes the Gateway-4 as a DSP-based 1RU IP codec designed for live remote broadcasting applications, as well as STL or SSL links. The Gateway-4 also includes support for AES67, ST 2110-30, AES3 and analog I/O as standard, and an optional WheatNet-IP card.

Gateway-4The Gateway-4 supersedes and replaces the Tieline Merlin and Genie STL audio codecs. It supports four full-duplex audio channels in 1RU to expand channel density by one when compared with these codecs.

The unit provides two stereo connections, or one stereo and two mono connections, or up to four mono full duplex connections. The Gateway-4 also supports multiple unicasting to up to 20 endpoints and multicasting.

The Gateway-4 supports four simultaneous full-duplex remotes
The Gateway-4 supports four simultaneous full-duplex remotes.

“The Gateway-4 is designed for solutions requiring between two and four audio streaming channels, plus unrivalled redundancy features and remote configuration and control,” said Charlie Gawley, VP Sales APAC/EMEA.  “Customers with higher channel requirements will gravitate toward the Gateway-8/16 multi-channel codec.”

For larger networks, Tieline describes the Gateway-4 as being “ideal for transmitter sites, remote trucks or rack-mounted remote kits.” For affiliates and smaller stations, the company says 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.

The Gateway-4 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. This allows the codec to integrate with legacy ISDN network infrastructure for primary or backup connections as required.

Gateway-4 codec delivers redundancy over IP and ISDN.

In addition, its feature set and compact design is interoperable with all Tieline IP codecs and compatible over SIP with all EBU N/ACIP Tech 3326 and 3368 compliant codecs and devices.

Gateway is configurable through an embedded HTML5 Toolbox Web-GUI interface and is also controllable using Tieline’s Cloud Codec Controller. Tieline expects to ship the Gateway-4 at the end of Q1.
