ISDN or Integrated Services Digital Network has long been accepted to be the better choice when compared to the older PSTN (Public Switched Telephone Network). Through ISDN, multiple data, including video, audio, and files can be digitally transmitted from one point in a network to another using a single line. In this article, we will show you the basics of ISDN and how your business can benefit from it.
Better signal quality = speed
The first obvious reason is speed. With ISDN, you get multiple digital channels, which means you can compress all channels and come up with a higher bandwidth than PSTN can deliver. With increased bandwidth, you’re able to accomplish a lot of things that was previously unavailable to normal modems, some of these include:
- Quicker connections, uninterrupted with no dialing or engaged tone.
- ISDN is also good for gamers because of its inherently faster connection.
- Video streaming and conferencing takes place with no disruptions.
- Video conferencing also allows multiple recipients.
With regular analog connection, the maximum possible speed on wire is 56 kbps, and is usually much lesser than this in the real world. Switching to ISDN gives you 64 Kbps per B channel, of which you use two. These two channels can be combined for speeds of 128 Kbps. In practice, ISDN is up to five times faster than a standard analog connection.
Not only is ISDN flexible, it's equally intelligent. Apart from its unique ability to combine lines to improve speed, the ISDN terminal adapter can spontaneously reduce your speed down to a single 64 Kbps B channel for data and allow the other channel to continue the voice call. Obviously, this feature must be reinforced by the hardware you’re currently using, but most ISDN connections do have such ability.
Multiple Channel functionality
Previously with PSTN, it was required to utilize a separate phone line for each device you want to use simultaneously. For instance, a line is required for computer, fax, telephone, router, bride, and live video conference system. Transferring files to another while engaged on a phone call or seeing them live on the video screen would require you to purchase potentially expensive phone lines.
ISDN in comparison allows multiple devices to share in one line. It’s become possible to connect different digital data sources and have the information routed to a specified destination. Video data, for example, can be digitally transmitted along with other kinds of data like audio.
Faster Data Transfer
Production speed is a major concern for any business. With ISDN, the two channels that provide the connection literally translate to faster data transfer rates. This is the main reason why much of the Internet, even email services, rely on ISDN in transferring multiple files across the network.
Despite the costlier application, the advantages of using ISDN for your business outweigh the cost. In the long term, companies will find it easier to regain the investment and reap the benefits of ISDN. This becomes apparent in terms of increased productivity figures and enhanced network capabilities.
