Originally, analog telecommunications services, also known as Plain Old Telephone System (POTS), were the only source of telecommunications worldwide, before ISDN came of age. POTS was the original acronym for Post Office Telephone System or Service, but changed when post offices stopped offering telephone service and consisted primarily of copper wires connecting the subscriber’s home to the telephone exchange. This type of telecommunications had its limitations. Long-distance calls had to be routed through operators and switchboards, which made them very unreliable and slow, and there was also the problem of static inference known as line noise, which disturbed communication.
ISDN stands for Integrated Services Digital Network and is a fully digital telephone line that can carry voice, image, video and digital network services. ISDN transceivers facilitate full fidelity and two-way communication between different locations. ISDN voice-overs are of excellent quality, extremely clear and free of background noise. As a user, you can be sure that your voiceovers will sound just as good as those recorded in your own studio. The benefits of using ISDN for Internet connections are much greater compared to using the old dial-up service as an Internet Service Provider (IPS). The ISDN dial-up connection offers speeds equivalent to a broadband connection. There are a number of additional benefits to using ISDN connections, as listed below:
multiple devices
In the past, you needed a separate phone line for each device, including service, fax, computers, and video conferencing. All of that has changed with the advent of ISDN, which comes with a host of features, including:
• Voice, data and video do not have interference or noise that impairs the quality of service, since the data is sent in packets or groups.
• Simultaneous transfer of services is possible with the same ISDN line, such as making calls, receiving faxes and connecting to the Internet, all at the same time.
• Each service has a signal that works with the ISDN network to ensure more history and fewer errors with multiple connections.
Velocity
Having multiple digital channels means you can compress all channels and generate bandwidths of up to 128 Kb/s. This is due to the 2 B-channels, each 64 Kb/s respectively. It allows you to achieve many things previously unavailable on regular modems, including:
• Faster direct connections, no dialing issues or downtime
• Video conferencing and streaming without interruptions
• Video conferences with multiple recipients
• Uninterrupted gaming thanks to faster connections
