Tieline Gateway 4

Brand: Tieline

The Gateway-4 is a powerful DSP-based 1RU IP codec designed for live remote broadcasting applications, as well as STL or SSL links. The Gateway-4 enables transport of multiple channels of mono or stereo audio across the Public Internet or any QoS-enabled IP network, including T1 and T3 connections and private WANs with MPLS. The Gateway includes support for AES67, ST 2110-30, AES3 and analogue I/O as standard.

Overview

The new generation Gateway-4 delivers best-in-class DSP-based reliability and performance for mission critical broadcast streaming applications. It is ideal for:

Remote broadcast applications.
Studio-to-Transmitter Links (STLs)
Studio-to-Studio Links (SSLs)

The Gateway-4 is designed for solutions requiring up to 4 audio streaming channels with advanced redundancy features and remote configuration and control. It supports 4 full-duplex audio channels in 1RU and is backward compatible with all Tieline IP codecs. The Gateway-4 provides two stereo connections, or one stereo and two mono connections, or up to 4 mono connections.
