US Patent 7961864 Local number portability cross connect method

A method is provided to implement a subscriber local number portability migration request. The method includes sending a trigger signal to a cross-connect device to cause the cross-connect device to switch between a first communication channel and a second communication channel. The first communication channel is between an originating switch associated with a subscriber's directory number and a distribution frame. The second communication channel is between a porting switch and the distribution frame. The method also includes validating that the cross-connect device switched between the first communication channel and the second communication channel.
