Tieline ISDN codecs provide simple, ultra-reliable, high-speed digital leased line connections that can connect over either ‘U' or ‘S/T' ISDN interfaces using Tieline ISDN modules. These modules slot neatly into Commander G3 field, rack mount and i-Mix codecs in seconds, providing connections between other Tieline codecs and a large range of different codec brands.
If you already own a Tieline codec, upgrading your codec for ISDN use is a simple process - just purchase an ISDN module, plug it into the codec, load the profile you require and you are ready to connect.
Are there Different ISDN Modules for Different Regions?
Tieline Technology originally sold two different ISDN modules; one for North America called the "US ISDN" module, and one for Europe and most other countries called the "Euro ISDN" module. Both of these modules are clearly marked as such and can continue to be used in these regions.
These modules were superseded and the "Euro ISDN G3"module is now the only module available. The Euro ISDN G3 module can be used in most countries outside North America and for all satellite ISDN connections. It can also be used over ISDN networks in the USA in conjunction with a small S/T to U ISDN adapter, which is shipped with every ISDN module intended for use in the United States. When ordering a module for US network use please make it clear that you will require the S/T to U adapter.

Compatibility with All Major Codec Brands
With Tieline ISDN you can connect to AEQ, AETA, APT, AudioTX, Comrex, Glennsound, Mayah, Orban, Prodys, STL IP and Telos codecs - to name just a few...
Higher Bit-rates, Higher Quality
Each ISDN plug-in module is capable of connecting to two ISDN B channels. Depending on the number of ISDN modules installed, field Commander codecs are capable of connections from 64kbps to 192kbps and rack codecs are capable of up to 256kbps.
Tieline ISDN provides up to 20kHz high-quality FM audio when connecting to all major codec brands using the highly compatible and popular MPEG1 Layer 2, G.722 and G.711 algorithms. For the highest quality you can choose from MP2 mono, dual mono, stereo or J-stereo.
Alternatively, you can save money on bandwidth by connecting between two Tieline codecs using Tieline MusicPLUS and achieve 20kHz stereo at 128kbps, with only 20ms of encoding delay. By using the Tieline Music algorithm you can achieve 15kHz stereo over a single 64kbps ISDN B channel, with a low 20ms encode delay.
Simple to Connect, Easy to Operate, Flexible to
All Tieline codecs feature one-touch connections over ISDN and all other supported transports. Remote codecs can be fully controlled and programmed from the studio using ToolBox software - so your announcers can concentrate on broadcasting. In addition, 1RU and 2RU Commander studio codecs can be remote controlled and programmed using a fully-optioned Graphic User Interface (GUI), that replicates the controls of the 2RU Commander codec front panel.
Tieline codecs also support connection to 3rd party codec control systems such as the widely used MDC.net management system from RaLex Solutions.
Flexible Codecs for Flexible Networks
With Tieline you can protect your investment in codec technology. As the demand for IP-based networks increases, audio codecs are increasingly expected to connect over a number of different network transports at different times. Install a Tieline rack-mount codec with a POTS and ISDN module in your studio and you can connect and broadcast over ISDN, POTS/PSTN IP, wireless 3G and even GSM any time you like!
Tieline offers broadcasters the latest connection software for one touch dialing over ISDN networks. We also offer:
- Automatic failover with complete redundancy over multiple network types and the ability to have connections such as POTS or IP simultaneously dialed up and streaming audio.
- Full remote control of connected codecs from the studio.
- A fully featured digital matrix router for routing inputs to your choice of digital and analog outputs.
- One touch dialing for connecting over IP and 3GIP networks.
- Future-proofing with the ability to connect over IP and 3GIP.
- The ability to connect to up to four 64kbps ISDN B channels simultaneously.
- Removable ISDN plug-in modules.
- Simple connection wizards for programming new connections
- Relay inputs and outputs for flexible machine control.
- The ability to connect over B-GAN satellite connections.
