Method and system for performing EMTA loop diagnostics

摘要

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.
