This is the system responsible for establishing calls and routing them within and to other networks.
The problem appeared to be with its Mobile Switching Center servers (MSC-S) a group of interconnected switching nodes that manage connections between subscribers or the interface through which calls are routed within the network using what is called the BICC protocol.

So, while the radio network system is sending the requests for connection, and they are being received, the establishment of the required connections is not taking place as it should. It is not clear if this is due to a physical fault like a broken cable, or a software malfunction particularly in the case of any software updates.
