∙ 11y ago
Both BRI (Basic Rate Interface) and PRI (Primary Rate Interface) provide multiple digital bearer channels over which temporary connections can be made and data can be sent.
Features:
ISDN BRI services 2 B channels (64 kbps) and one D channel (16 kbps). The total bandwidth is 144 kbps.
In North America ISDN PRI service is PRI T1 total bandwidth 1.544 Mbps ( 23 B channel with 64 kbps + 1 D channel with 64 Kbps)
In Europe ISDN PRI service is PRI E1 total bandwidth 2.048 Mbps (30 B channel with 64 kbps + 1 D channel with 64 Kbps)
PRI: Expensive
BRI: Less cost
PRI: Large scale service suitable for companies
BRI: Small service suitable for home and small business
