Abstract
Automated processes, devices and systems isolate signals received on first and second ports from each other using staggered time division multiple access (TDMA) schemes. Additionally or alternately, port and/or client identifiers can be included within communications propagating in multiple TDMA schemes, thereby allowing host and/or client devices to verify that communications are received on the intended ports. By logically isolating the communications of the multiple TDMA schemes and/or by providing identifying information within propagated communications, crosstalk between the two schemes can be substantially reduced or eliminated, often without substantial modifications to the hardware configuration of the system.
