Method and system for performing EMTA loop diagnostics
Diagnostic testing of a telephony line card device and corresponding line card is initiated using an initiation MIB. Responding to an instruction from a main processor that a query has determined that an initiation MID is Set, line card processor circuitry begins a predetermined series of diagnostic testing. Results for the diagnostic testing are stored in a register coupled to the line card processor circuitry. After testing completes, the main processor, which is coupled to the line card processor, retrieves the results information from the line card register, converts the information to one or more results MIB(s) and stores the results MIB(s) as an instance(s) to a memory coupled to the main processor. The result MIB instance(s) is/are made available to a local or remote device via port coupled to the line card device. A permissive MIB may be queried to determine whether diagnostic testing is permitted.
1. A system for performing line and diagnostic testing in an EMTA device comprising:
processor circuitry for performing diagnostic testing on subscriber telephone wiring and equipment based on an initiation object instance initiated from a remote service operator;
first memory coupled to the processor circuitry for storing the initiation object instance;
second memory coupled to the processor circuitry for storing result information that corresponds to the results of the diagnostic testing on the subscriber telephone wiring and equipment; and
third memory coupled to the processor circuitry for storing the result information in a result object instance, wherein the contents of the result object being available to the remote service operator.
2. The system of claim 1 wherein the first and third memories are separate portions of a physical memory.
3. The system of claim 1 wherein the initiation object and result object are management information base objects.
4. The system of claim 1 wherein the second memory is a separate memory from the first and third memories.
5. A method for performing diagnostics of a loop coupled to an EMTA device, comprising:
reading initiation information in an initiation object initiated from a remote service operator;
performing diagnostic testing on subscriber telephone wiring and equipment according to the initiation information;
storing result information corresponding to results of the diagnostic testing to a register; and
storing the result information to a result object, the contents of the result object being available to the remote service operator.
6. The method of claim 5 further comprising querying a permissive key object to determine whether performing diagnostic testing is enabled.
7. The method of claim 5 wherein the initiation object is a MIB object.
8. The method of claim 5 wherein the result object is a MIB object.
9. The method of claim 7 wherein the initiation information is stored as a MIB instance.
10. The method of claim 9 wherein the initiation information is transmitted from a device remote from the EMTA device.
11. The method of claim 8 wherein the result information is stored as a MIB instance.
