Apparatus and method for controlling cross-connection in a digital cross-connect system

摘要

In a B-DCS (broadband digital cross-connect system) having plural input/output ports, a cross-connect control apparatus for a B-DCS includes a cross-connect signal generating unit which generates signals for setting cross-connects based on input cross-connect commands, and a switching unit installed at the output ports for establishing a cross-connect between an input port and an output port according to cross-connect signals from the cross-connect generating unit. A cross-connect control method for a DCS (digital cross-connect system) includes receiving a cross-connect command; generating an input/output port address and a connect/release request signal according to the cross-connect command; transmitting an input port address to be connected to each output port; generating an enable signal (W_EN) indicating a cross-connect setting between the output port and the input port; judging whether the output port is in a preset cross-connect state based on the enable signal; generating an error message when the output port is in the preset cross-connect state; and establishing cross-connect between the output port and the input port when the output port is not in the preset cross-connect state.
