Abstract

A method and apparatus for performing automatic trouble isolation for a Digital Subscriber Line Access Multiplexer (DSLAM) used on packet networks are disclosed.

Claims

1. A method for trouble isolation of DSLAM, comprising:

receiving a request or a ticket for trouble isolation associated with a Digital Subscriber Line (DSL) service;

performing connectivity test to customer premise equipment to differentiate between failures in customer premise versus network;

performing connectivity test to an ATM or FR switch to differentiate between failures in DSLAM versus ATM/FR switch network;

performing connectivity test to Digital Subscriber Line Access Multiplexer (DSLAM);

isolating software and configuration failures of DSLAM by performing one or more logical tests; and

isolating physical failure of DSLAM by performing one or more test for physical failures.

2. A computer-readable medium having stored thereon a plurality of instructions, the plurality of instructions including instructions which, when executed by a processor, cause the processor to perform the steps of a method for trouble isolation of DSLAM, comprising:

receiving a request or a ticket for trouble isolation associated with a Digital Subscriber Line (DSL) service;

performing connectivity test to customer premise equipment to differentiate between failures in customer premise versus network;

performing connectivity test to an ATM or FR switch to differentiate between failures in DSLAM versus ATM/FR switch network;

performing connectivity test to Digital Subscriber Line Access Multiplexer (DSLAM);

isolating software and configuration failures of DSLAM by performing one or more logical tests; and

isolating physical failure of DSLAM by performing one or more test for physical failures.

3. An apparatus for trouble isolation of DSLAM, comprising:

means for receiving a request or a ticket for trouble isolation associated with a Digital Subscriber Line (DSL) service;

means for performing connectivity test to customer premise equipment to differentiate between failures in customer premise versus network;

means for performing connectivity test to an ATM or FR switch to differentiate between failures in DSLAM versus ATM/FR switch network;

means for performing connectivity test to Digital Subscriber Line Access Multiplexer (DSLAM);

means for isolating software and configuration failures of DSLAM by performing one or more logical tests; and

means for isolating physical failure of DSLAM by performing one or more test for physical failures.
