Abstract (en)
[origin: WO0042750A1] A bandwidth transfer switching system (100) connecting various customer devices (12a-g), including local area networks (44), from customer premises (42) through a local loop (50) to a telco central office (50), to deliver switched circuit traffic to central office switches (60) and data packet traffic to wide area networks (64), such as the Internet. Access concentrators (104, 140) are employed at the customer premises (42), remote concentrators (106, 140) and optional relay nodes (160, 140) are employed in the local loop (50), and transfer switches (108, 140) are employed in the central office (56). Copper wire lines (166) and fiber optic lines (168) are used to handle typical protocols such as POTS, E1/T1/xDSL, and SONET between the various transfer nodes (140).
