Just because it's two-wire doesn't mean it's not full-duplex. I have a schematic for a circuit that will do (IIRC) 10mbit FULL DUPLEX over one pair of wires. It does so by level-shifting the transmit and receive into different "voltage ranges". While this isn't what HDSL2 is doing, I am certain that HDSL2 is full duplex as well. -A. _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
