System and method for performing subscriber loop testing in an optical network
View Patent ↗An access network includes a test system controller that provides a test request in Signaling Network Management Protocol (SNMP) messages to an element management system. A network gateway, in conjunction with the element management system, provides test commands to a customer gateway over a Local loop Emulation Service Embedded Operations Channel (LES-EOC). The customer gateway performs a subscriber loop test on derived subscriber lines connected therewith. Results of the subscriber loop test are provided over the LES-EOC to the gateway. The network gateway sends the results to the test system controller through the element management system in SNMP messages.
1. A method for performing subscriber loop testing in an optical network, comprising:
receiving a request to initiate a loop test;
identifying a customer gateway to which test commands are to be sent;
transmitting test commands toward the identified customer gateway to perform a subscriber loop test;
performing a channel test on an optical fiber link to the customer gateway;
requesting results of the subscriber loop test;
receiving the results of the subscriber loop test;
providing results from the channel test and the subscriber loop test to a test system controller.
2. The method of claim 1 , wherein the request is received through Signaling Network Management Protocol (SNMP) messages.
3. The method of claim 2 , further comprising:
converting the request into test commands;
placing the test commands in SNMP messages;
transmitting the SNMP messages containing the test commands to the customer gateway over a Local loop Emulation Service Embedded Operations Channel (LES-EOC).
4. The method of claim 2 , wherein the results are provided through SNMP messages.
5. The method of claim 4 , further comprising:
receiving the results of the subscriber loop test over a Local loop Emulation Service Embedded Operations Channel (LES-EOC);
converting the results of the subscriber loop test into SNMP messages.
6. The method of claim 1 , wherein test commands are transmitted to the customer gateway over a Local loop Emulation Service Embedded Operations Channel (LES-EOC) path.
7. The method of claim 6 , wherein the results of the subscriber loop test are received over the LES-EOC path.
8. A system for performing subscriber loop testing in an optical network, comprising:
means for receiving a request to initiate a loop test;
means for identifying a customer gateway to which test commands are to be sent;
means for transmitting test commands toward the identified customer gateway to perform a subscriber loop test;
means for performing a channel test on an optical fiber link to the customer gateway;
means for requesting results of the subscriber loop test;
means for receiving the results of the subscriber loop test;
means for providing results from the channel test and the subscriber loop test to a test system controller.
9. The system of claim 8 , wherein the request is received through Signaling Network Management Protocol (SNMP) messages.
10. The system of claim 9 , further comprising:
means for converting the request into test commands;
means for placing the test commands in SNMP messages;
means for transmitting the SNMP messages containing the test commands to the customer gateway over a Local loop Emulation Service Embedded Operations Channel (LES-EOC).
11. The system of claim 9 , wherein the results are provided through SNMP messages.
12. The system of claim 11 , further comprising:
receiving the results of the subscriber loop test over a Local loop Emulation Service Embedded Operations Channel (LES-EOC);
converting the results of the subscriber loop test into SNMP messages.
13. The system of claim 8 , wherein test commands are transmitted to the customer gateway over a Local loop Emulation Service Embedded Operations Channel (LES-EOC) path.
14. The system of claim 13 , wherein the results of the subscriber loop test are received over the LES-EOC path.
