    摘要: Systems and methods for detecting a status of a telephone line. Some of the systems include a telecommunications system which comprises a dial tone tester integrated with a demarcation device. Such dial tone testers can include a visual device or an audible device indicative of line status. Various methods are also described for detecting the status of a telephone line. Such methods can include receiving a response originating from a customer premises, viewing a demarcation device located at the customer premises, and determining line status from a dial tone tester integrated with the demarcation device.
