Abstract
A grooming device (18) includes an inbound crosspoint switch (30) that combines proprietary STS-1 signals from any of a plurality of optical terminators (16) into a grouped set of output signals for transmission to a broadband matrix subsystem through dedicated matrix interfaces (20). The inbound crosspoint switch (30) includes a crosspoint matrix (72) that receives each of the plurality of input signal lines at each output signal port and selects which input signal line is connected to which output signal port as determined by a microprocessor controller (78). Each output signal port has a register (90) for storing information as to which input signal line is to be connected to that port. A decoder (92) generates a control signal from the information stored in the register (90) to drive a multiplexer (94) for selection of the appropriate input signal line.
