ISDN
ISDN Digital Connectivity for Your Evolving Voice, Video and Data Transport Needs
Integrated Services Digital Network (ISDN) is an all-digital communications service that gives your standard phone lines the ability to transmit voice, data and video at very high speeds at a relatively low cost.
There are two types of ISDN service:
- Primary Rate Interface (PRI): Ideal for larger businesses.
- Basic Rate Interface (BRI): Perfect for small-scale businesses.
Both BRI and PRI use channels called "B", or Bearer channels, and "D", or Delta channel. The B channels provide a transmission path for user information, such as voice and data, while the D Channel carries signaling information, such as call setup and packet data.
ISDN PRI
ISDN PRI is an ideal business voice and data solution for:
- Offices using a PBX solution, phone system or customer premises equipment
- Large call centers
- Room-sized video conferencing
- Backing up dedicated private lines
An ISDN PRI connection supports 23 individual 64 kbps B-channels and one 64 kbps D-channel over a high-speed circuit. 23 channels can be used in various combinations for specific communications needs.
ISDN BRI
ISDN BRI is a small business voice and data solution providing high-quality, switched digital communications service. An ISDN BRI connection supports two individual 64 kbps B-channels, plus one 16 kbps D-channel.
ISDN services are an ideal solution for growing and large businesses that need a cost-effective digital connection for clear voice and high-quality data traffic with increased speeds, reliability and scalability.
- Cost-effective integrated digital access. One connection can be used for multiple services, multiple devices and multiple destinations, reducing the need for additional circuits.
