Excellence in Broadcast

Tieline Gateway

The Tieline Gateway is the most powerful DSP-based 1RU IP codec enabling transport of multiple channels of mono or stereo audio across the public internet and any QoS-enabled IP network, including T1 and T3 connections and private WANs with MPLS. The Gateway streams up to 16 IP audio channels with support for AES67, ST 2110-30, AES3 and analogue I/O as standard.

Overview

The Tieline Gateway introduces a new era in high-density multichannel IP codec streaming. The Gateway supports up to 16 mono channels or 8 stereo streams of bidirectional IP audio in 1RU to increase efficiency and reduce rack space requirements. It interfaces easily with legacy analogue and AES/EBU digital sources, as well as newer broadcast plants with AES67 and ST 2110-30 IP audio infrastructure. An optional WheatNet-IP card is also available.

The Gateway is perfect for large-scale audio distribution to single or multiple locations, as well as managing multiple incoming remotes at the studio using SmartStream PLUS redundant IP streaming and Fuse-IP data aggregation technologies over internet connections. It is interoperable with all Tieline IP codecs and compatible over SIP with all EBU N/ACIP Tech 3326, 3347 and 3368 compliant codecs and devices.
