Abstract
Systems and methods are disclosed for testing the functionality of a synchronous optical network having a data communication channel therein. The system includes a testing device connected to a network node within the synchronous optical network and a data communication channel loop back plug connected to the testing device for returning to the synchronous optical network, any signals within the data communication channel received at the testing device. A method is also disclosed for testing a synchronous optical network having a data communication channel therein.
Claims20
A system comprising:
- a testing device configured to be connected to at least one network node of an optical communications network having a data communication channel, the testing device being configured to receive signals from the data communication channel of the network node;
- and
- a data communication channel loop back plug coupled to the testing device for returning to the network node any signals within the data communication channel received at the testing device, the data communication channel loop back plug comprising a plurality of pins, at least one of the pins being shorted to at least one other of the pins to return to the network node any signals within the data communication channel received at the testing device,
- wherein the data communication channel loop back plug comprises:
- i) a 15 pin connector, and wherein pin 2 of the data communication channel loop back plug is shorted to pin 14, pin 4 is shorted to pin 12, pin 5 is shorted to pin 6, and pin 8 is shorted to pin 10, or
- ii) a 37 pin connector, and wherein pin 4 of the data communication channel loop back plug is shorted to pin 6, pin 8 is shorted to pin 17, pin 22 is shorted to pin 24, and pin 26 is shorted to pin 35.
A data communication channel loop back plug comprising:
- a plurality of pins, at least one of the pins being shorted to at least one other of the pins to return to a communications network having a communication channel any signals received from the communication channel,
- wherein the data communication channel loop back plug comprises:
- i) a 15 pin connector, and wherein pin 2 of the data communication channel loop back plug is shorted to pin 14, pin 4 is shorted to pin 12, pin 5 is shorted to pin 6, and pin 8 is shorted to pin 10, or
- ii) a 37 pin connector, and wherein pin 4 of the data communication channel loop back plug is shorted to pin 6, pin 8 is shorted to pin 17, pin 22 is shorted to pin 24, and pin 26 is shorted to pin 35.
A method of testing an optical network having a plurality of network nodes, the method comprising:
- attaching a testing device to the optical network;
- attaching a data communication channel loop back plug to the testing device such that the testing device is capable of transmitting any received signals from the optical network back to the optical network, the data communication channel loop back plug comprising a plurality of pins, at least one of the pins being shorted to at least one other of the pins to return to the optical network any signals within the data communication channel received at the testing device;
- inserting a payload into the network;
- and
- monitoring the optical network for any communication faults, wherein attaching a data communication channel loop back plug to the testing device comprises attaching:
- i) a 15 pin connector, and wherein pin 2 of the data communication channel loop back plug is shorted to pin 14, pin 4 is shorted to pin 12, pin 5 is shorted to pin 6, and pin 8 is shorted to pin 10, or
- ii) a 37 pin connector, and wherein pin 4 of the data communication channel loop back plug is shorted to pin 6, pin 8 is shorted to pin 17, pin 22 is shorted to pin 24, and pin 26 is shorted to pin 35.
