  • All such tests are initiated by a network device which comprises of the required test equipments and/or software utilities used to perform the tests or they can be initiated by a network operator.
  • the tests are initiated over a link connecting the network device to a subscriber and in particular to an apparatus that the subscriber uses to connect to the communications network.
  • off-peak time periods are chosen for the running of the tests, usually late at night or very early in the morning.
  • the measurements do not correspond to the rush hour time period, thus not providing a good indication of the connectivity and/or quality of the connection over the link.
  • the tests performed do not reflect the actual link status and any results generated will be erroneous .
  • This need also has to take into account the fact that in today's communications networks, subscribers might have a plurality of apparatuses that are linked to the same subscription, and it is necessary to provide effective ways to ensure that network failures can be discovered in a timely manner, thus maintaining a high quality of line connectivity.
  • the proposed technique reduces the complexity and manufacturing costs of network testing devices, link failures are easily spotted and effective management of network resources achieved.

  • no ring signal is executed.
  • the testing utilities of the switch 20 Upon the connection being set up, the testing utilities of the switch 20 will perform the required testing of the link 11 (media test, step 3) . Once the testing is completed and the required results gathered, the link 11 is released and the results are gathered into a report and in turn transmitted via a SNMP (Simple Network Management Protocol) for further analysis elsewhere in the communications network and upon termination of the test the link 11 is again returned to an idle state (step 4) .
  • SNMP Simple Network Management Protocol
  • Fig. 2 shows the mechanism for testing a link as is currently used in the art when a failure occurs. It is similar to the setup of fig. 1. It only differs in that the CPE 10 is not connected, therefore, the test setup message transmitted will not be received by the CPE 10. After a time out period the link 11 is released and is again returned to an idle state. A result report indicating that a failure occurred is then transmitted in the same fashion as described in fig. 1.

  • the CPE 10 has control means 170 that will begin the process of testing either at a specific time based on the setup of the CPE or periodically using a clock means 150 to provide the required periodicity, or at a desired usage-time-window specified by the CPE 10 setup or on receiving a request from a subscriber or from a first network device 20 or when connecting to the communications network.
  • the control means 170 on beginning the process, indicate to a setup test/connect means 110 to transmit a setup test message via a transmit/receive means 100 to the first network device 20.
  • This first network device 20 is a device to which the CPE 10 is connected to via link 11.
  • the first network device 20 is preferably a switch 20 and in particular a layer 2 or a layer 3 switch or a soft-switch or a PBX (Private Branch Exchange) switch, or a telephone network entity device.
  • Link 11 can be a line connection for example a copper wire connection or a fibre optic connection or a wireless connection.
  • the switch 20 comprises of a transmit/receive means 210 adapted to receive and transmit messages and a loop back creation means 220 adapted to create a loop back circuit on the switch 20, upon reception of a setup test message being received and switch control means 230 notifying it to set up the loop back circuit.
  • the CPE 10 transmits the setup test message to the switch 20 (step 1) .
  • the switch 20 sets up a loop back circuit back to the CPE 10 and sets up a connection to the switch step 2.

  • Steps 1 to 4 are repeated periodically or as often as necessary depending on the setup of the CPE 10. Each time testing is performed all the required results are gathered and stored in the storage means 160.
  • the control means 170 Upon a predefined number of tests being reached, this being fixed either by the subscriber in a subscriber profile stored on the CPE 10 in the storage means 160 or by a service provider providing a service to the subscriber, the control means 170 will indicate to a report/analysis means 140 to retrieve the stored results and generate a report.
  • This report is then transmitted via SNMP or alternatively by using a proprietary protocol designed for transmitting the generated reports, to a second network device 30 (step 5) .
  • This second 30 being preferably a server used by the service provider to collect and collate testing results, such as a central server.
  • the report/analysis means 140 are also adapted to perform if necessary an error analysis on the results as well. When an error analysis is performed the results are also transmitted via SNMP or by the proprietary protocol to the second network device 30.
  • the generation of the report can also be initiated by the switch 20 requesting it.
  • Fig. 4 shows in detail the mechanism of the proposed invention when a failure occurs. It is similar to the setup of fig. 3. It differs in that at some point in time, the link 11 to the switch 20 is lost.
  • the setup test message is transmitted as explained above and after a time out period, as no connection is setup by the switch 20 responding to the reception of the message, an error will be generated by the setup test/connection means 110 and stored in the storage means 160.
  • the testing process is repeated, upon the link 11 re-establishing its connectivity between the CPE 10 and the switch 20, the test will be successful, and upon the transmittal of the report, the generated error will also be included in it.
  • the gathering of a plurality of test results is particularly- advantageous as it allows CPE' s that have multiple POP' s (Point of Presence) , to move from one point in the communications network to another, such as from one network interface to another one and be able to initiate testing with regards to the current connectivity.
  • POP' s Point of Presence
  • the signalling used by the CPE 10 to test the connectivity to the switch 20 is standard signalling, allowing the CPE 10 to be able to perform testing with switches of different manufactures and in network environments of different providers .
  • each CPE 10 initiates its own testing individually no conflict is caused when multiple CPEs are connected to the same subscription. Also, there is no need for specific hardware, software requirements to be incorporated into network devices, such as switches, as the only requirement is the necessity for having means that can set up a loop-back circuit. Furthermore, since a CPE 10 is a mass produced product, it is more cost effective to realise the link testing in the CPE 10 instead of in the switches. Furthermore, in a preferred embodiment, if during the execution of the testing procedure an incoming call arrives, the CPE 10 is arranged to abort the testing procedure in order to allow the incoming call to be processed. The aborted testing can then be resumed at a later time.
