1. A line card for a digital subscriber line access multiplexer (DSLAM), comprising:
- a plurality of physical ports, each physical port supporting a connection to a digital subscriber line; and
a virtual port that appears to an administrator workstation as a test port on the line card, the virtual port being configured to permit a test host to link to subscriber services provisioned for a physical port to be tested on the line card, to permit Layer 2 and above testing of those subscriber services.

Abstract
A method and apparatus to permit testing of Layer 2 and higher services provisioned for a port on a digital subscriber line access multiplexer (DSLAM) line card. Each line card is provisioned with a virtual port, a virtual port cross-connect function, and a virtual port tunneling function. The virtual port can be linked to any physical port on the line card. A test host can link to the virtual port from anywhere in a network to perform verification of end-to-end service provisioning and functionality throughout a network.

15. A method of verifying end-to-end service provisioning and functionality throughout a network used to provide digital subscriber line service to a service subscriber connected to a digital subscriber line access multiplexer (DSLAM), comprising:
-
configuring a virtual port on the line card to link to the provisioned subscriber services; selecting a test host protocol stack to match a protocol stack of customer premises equipment used by the subscriber; logically connecting to the virtual port using the test host; and operating the test host to verify the provisioned subscriber services. - View Dependent Claims (16, 17, 18, 19, 20)
