## Abstract

A diagnostic device for a communications network; the network comprising a customer communications network located at a customer location and connected by a customer communications link to a communications service provider network remote from the customer location. The device comprises a network monitoring interface arranged to monitor operation of the customer communications network; a processor arranged to detect faults in the operation of the customer communications network, a store for storing records of detected faults; a processor arranged to store records of detected faults in the store and to generate a report on a detected fault based on the stored records. The device is co-located with the customer communications network and further comprises: a first communications interface arranged to send to the communications service provider network via the customer communications link, the report generated on the detected fault; and a second communications interface arranged to send to the communications service provider network via a second communications link, the report generated on the detected fault.

### Claim 11 (depends on 1)

The diagnostic device of claim 1, wherein the fault report information comprises information relating to a cause of a detected fault.

### Claim 12

A diagnostic device for a communications network;
wherein the communications network comprises a customer communications network located at a customer location and connected by a customer communications link to a communications service provider network remote from the customer location;
wherein the diagnostic device comprises a network monitoring interface arranged to monitor operation of the customer communications network; a processor arranged to detect faults in the operation of the customer communications network, a storage for storing records of detected faults; wherein the processor is arranged to store records of detected faults in the storage and to generate a report on a detected fault based on the stored records;
wherein the diagnostic device is arranged to be co-located with the customer communications network and further comprises:
a first communications interface arranged to send to the communications service provider network via the customer communications link, the report generated on the detected fault; and
a second communications interface arranged to send to the communications service provider network via a second communications link other than the customer communications link, the report generated on the detected fault;
wherein the first communications interface and/or the second communications interface is arranged to send to the communications service provider network a prompt to initiate testing from the communications service provider network of the customer communications network and/or the customer communications link.

### Claim 13
