What is ISDN codec

[Appaji]

Hi all,

I am a student of university of ohio and doing telecommunication engineering.I am doing a project over telephone line mechanism. Basically it all over the ISDN based topology project. I know the ISDN is a digital line technology service but what is ISDN codec. Is a software or hardware? Please clarify and suggest. Thanks.

A ISDN codec is a device used in broadcast engineering to drive sound reproduction digital audio over usual telephone lines. It is a hardware codec, apply with digital signal processing, is utilize to compress the audio data sufficient to travel at a bitrate equal to a 56k modem. therefore, it is a modem able to use simple old telephone service to send monophonic audio. You can also check more information on the Google search. Best of luck.

The main use of a ISDN codec is for remote broadcasting. It is basically used in radio station. ISDN has the advantage of creature natively digital, and a full 64 or 128kb/s while using both channels, which consequences in fewer density and potential density object. Though, special lines must be run to a site, and must be prepared well in advance of the event so that there is abundance of time for installation. It is engineering term. Check it and reply.

AudioTX Communicator is present the ISDN codec .This Software provide ISDN Codec with APTx and MPEG codingPLUS. You can use Connections over ADSL, DSL, IP Networks, ATM and Ethernet . It also uses standard PC Sound card and ISDN hardware. It compatible with COMPATIBLE w/ CDQ Prima, Telos Zephyr, Glensound and works on a LAPTOP or even a a standard PC. Best of luck.

Basically ISDN is not fairly the same all over the world. Telecomms companies providers in different countries may use somewhat different ISDN protocols. When you buy a codec, you buy it with the right type of Terminal Adapter installed. Some terminal adaptor can be switch to work with dissimilar protocols; others are fixed to one or a range of them. This is only a case of you having the right tools to connect to your line somewhat like having a 110v or 220v toaster. You have to have the right power supply. Check that and reply.
