What is an ISDN Phone?
An integrated services digital network - or ISDN - is a process of communication that allows for the transmission of voice, video, data and other network services at the same time, over the traditional public switched telephone network - or PSTN.
Essentially, an ISDN phone system allows businesses to combine all of their communication channels into one, without forcing them to purchase a number of analogue phone lines to handle the transmissions. This ability allows for simplicity in a business’s communications, as well as for more streamlined processes.
ISDN has been the main business communications solution for a number of years, and so many administrators will already be aware of it. Indeed, given this understanding, it is likely that many businesses will prefer to use ISDN in order to stay with a system that they understand and are used to.
A VoIP phone system is an alternative choice that some businesses may prefer.
What is an ISDN Line?
An ISDN line is simply the digital line that is used to transmit digital data over a data network. With an ISDN line, you are normally able to guarantee voice, data or video quality - this is not always possible with alternative forms.
ISDN Line Costs
ISDN lines come in a variety of forms, meaning that businesses of all sizes are able to choose the one most suited to their needs. Knowing which option you require is vital if you want to understand what you might have to pay; it is also important to consider what you may need in the future. Implementing the lowest volume ISDN functionality may make sense now, but if you are likely to need improvements in the future, then it may turn out not to be the best choice.

How does ISDN Work?
An ISDN line is a digital line, and so it will work best with digital-ready phones. However, you can connect your regular analogue signal phone to an ISDN line via a terminal adapter, which in turn is connected to your computer.
With the computer, this adapter can convert analogue signals from your regular phone into digital signals which can be used to transfer data and voice calls to the internet.
ISDN local calls cost the same price as analogue and regular phone calls, but offer benefits in caller identification, call back, call waiting and conferencing options.
The most basic ISDN benefit lies in its ability to facilitate a business user with multiple digital channels. Unlike with some non-ISDN options, these channels can operate simultaneously through one access point.
Additionally, an ISDN line provides a high data range that is compatible with a number of devices, from phones, to computers and cash registers. All of these devices are able to operate at once, making use of just a single line.
Finally, whereas some other forms of communication modem can take as long 30 seconds to establish a connection, an ISDN phone line typically completes the task in 2 seconds.
