ABSTRACT:
Example distributed DSLAMs to increase bandwidth in access networks are disclosed. An example DSLAM comprises a first distribution cable segment to couple an SAI to a first pedestal and to transport user data, a second distribution cable segment to couple the first pedestal to a second pedestal and to transport a first portion of the user data from the first pedestal to the second pedestal, the second cable segment comprising a pair of DSL-based signals bonded together, a drop cable to couple the first pedestal to a customer premises and to transport a second portion of the user data to the customer premises, and a switch at the first pedestal to route the first portion of the user data between the first and second cable segments and to route the second portion of the user data between the first cable segment and the drop cable.
