No, it's also called PRI (or ISDN30), but its a different one... USA-pri is T1, 1,5 Mbps 23 * 64kbps channels + one 64 kbps D-channel. In Europe pri is E1, 2,048 Mbps made up of 32 * 64 kbps but two of those channels are not used for voice. One is used for signalling (also known as D-channel) and the other (used to be needed) for synchronisation. BRI is the isdn variant for home use: 144 kbps. Two 64kbps voice channels and a much smaller D-channel (16kbps) for signalling. hw _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
