ISDN Details
Primary Rate Interface (PRI) is ideal for larger businesses.
PRI uses channels called "B", or Bearer channels, and a "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 service is used primarily by large organizations with intensive communications needs. An ISDN PRI connection supports 23 individual 64 kbps B-channels and one 64 kbps D-channel over a high-speed circuit. ISDN PRI is ideal for offices using a PBX solution, phone system or customer premises equipment, large call centers, room-sized video conferencing or backing up dedicated private lines.
The advantage of primary rate interface or PRI is that the 23 channels can be used in various combinations for specific communications needs
