Local number portability cross connect switch network

摘要

A cross-connect switch ( 16 ) for implementing local number portability between a current local service provider originating switch ( 14 ) and a desired local service provider ported switch ( 18 ). The cross-connect switch ( 16 ) is connected in a line associated with a subscriber's directory number between the originating switch ( 14 ) and a main distribution frame ( 12 ) to establish a first active communication channel. The cross-connect switch ( 16 ) is also connected in-line between the ported switch ( 18 ) and the main distribution frame ( 12 ) to establish a second inactive communication channel. The cross-connect switch ( 16 ) is signaled to automatically deactivate the first communication channel and activate the second communication channel thereby routing communications associated with said subscriber's directory number to the ported switch ( 18 ).
