Abstract
An architecture for stacking DSLAMs employs a master DSLAM having a control circuit and an uplink communication circuit to a central office and two LVDS circuits for communication with two DSLAM boxes in adjacent circuit interconnection to the master DSLAM. Multiple slave DSLAMs each having a programmable control circuit and two LVDS circuits for communication with two DSLAM boxes immediately adjacent on either side in the circuit are connected in a ring or split stack arrangement. A control circuit in the master selectively programs the control circuits in each slave DSLAM to control the direction of communication in the LVDS circuits as round robin in a first selected mode and a split in a second selected mode to accommodate the desired structure.
