Abstract
A loop around system and method for use in a telephone line monitors line conditions to detect the initiation of loop testing and automatically bypasses an electronic device, such as a DSL line conditioner, used in the line to prevent the electronic device from being inadvertently detected by the testing system as a line fault. The system additionally shuts down power to itself from the line so that it does not interfere with testing, while continuing to monitor the line during testing to detect conditions that characterize the termination of testing, and then automatically switches the electronic device back into the line upon the conclusion of testing. The system and method may be employed unattended at intermediate locations in the line remote from the CO or the CPE.
