Tieline Announces
New Gateway-4 IP Codec
L

eading codec manufacturer Tieline
has announced the addition of the
new Gateway-4 IP audio codec to its
range of professional IP audio codecs.
The Gateway-4 is a powerful DSPbased 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-4 Replaces Merlin
and Genie STL Codecs
The Gateway-4 supersedes and
replaces the popular Merlin and
Genie STL audio codecs. It supports 4
full-duplex audio channels* in 1RU to
expand channel density by one when
compared with these codecs.
The Gateway-4 provides two stereo
connections, or one stereo and two
mono connections, or up to 4 mono
full duplex connections. The Gateway-4
also supports multiple unicasting to up
to 20 endpoints and multicasting.
" Tieline's new generation Gateway
codecs deliver best-in-class DSPbased 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-8/16 multichannel codec. "
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-tostudio links, or a stereo studio-totransmitter 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.
This allows the codec to integrate with
legacy ISDN network infrastructure
for primary or backup connections as
required.
Its feature-rich 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.

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

Gateway-4 codec
delivers redundancy
over IP and ISDN

Tieline expects the codec to ship
towards the end of Q1, 2021.
Gateway is configurable through an
embedded HTML5 Toolbox Web-GUI
interface and is also fully controllable
using Tieline's Cloud Codec Controller.

Gateway-4 supports
4 simultaneous
full-duplex remotes

Rear Panel Interfaces
The Gateway rear panel facilitates
maximum flexibility with support for
analog, AES3 and AES67 / ST 211030 I/O. Tieline also offers optional
WheatNet-IP compatibility via dual
AoIP ports. The codec supports 8
GPIOs as well as software logic I/Os.
The module slot allows an optional
Euro ISDN module to be installed in
the codec for network connection
flexibility and redundancy. This
module slot can also be used for
future hardware innovation upgrades
to maximise the effective life of the
codec.

Front Panel Interfaces
The Gateway front panel has 8 PPMs
to view input and output streams. It
also features a high-quality color LCD
screen for at-a-glance monitoring
and configuration. Silicon menu,
navigation and keypad buttons deliver
simple configuration, control and
audio monitoring. An SD card slot
and USB port allow simple access for
firmware upgrades, attaching Wi-Fi
USB modems, and additional memory.
