Abstract
A method includes the step of serially clocking a mask value through a plurality of subscriber line interface circuits (SLICs) until each SLIC stores a corresponding portion of the mask value, and serially communicating a command to the plurality of SLICs. Each SLIC responds to the command only if enabled by the corresponding portion of the mask value.
