Patent ID: 8417795

Claim:
A method of provisioning a service, comprising: provisioning a service for a network access device (NAD); creating the service in an operationally disabled state responsive to provisioning the service; associating an expected network interface unit (NIU) identification code with the NAD responsive to provisioning the service; detecting a first NIU connecting to a first facility on the NAD, the first NIU having a first identification code associated therewith; comparing the first identification code of the first NIU with the expected NIU identification code; transitioning the service to an operationally enabled state on the first facility only if the first identification code of the first NIU matches the expected NIU identification code; detecting the first NIU disconnecting from the first facility; transitioning the service to an operationally disabled state responsive to detecting the first NIU disconnecting from the first facility; detecting a second NIU connecting to a second facility on the NAD, the second NIU having a second identification code associated therewith; comparing the second identification code of the second NIU with the expected NIU identification code; and transitioning the service to an operationally enabled state on the second facility if the second identification code of the second NIU matches the expected NIU identification code indicating that the first and second NIUs are the same NIU.
