Abstract
The invention relates to a system and a method for implementing ISDN user port status monitoring in a network element transmitting messages in a cascaded V5 interface. In an embodiment of the invention, ISDN user port activation messages are transmitted unaltered through the message transmitting network element when the current state of the ports is other than the BLOCKED state consistent with the V5 definitions.
