A synchronous optical network (SONET) demarcation device can be placed on a customer premises to enable remote testing and trouble shooting of customer premises equipment. The device includes a SONET signal analyzer that extracts SONET data, such as section, line and path overhead. The SONET demarcation device also includes a SONET fault condition, performance statistics, and alarm generator that generates fault conditions, performance statistics, and alarms based upon the extracted SONET data. The device also includes a transmitter that transmits the alarm and/or performance data to a remote site. The SONET demarcation device does not include ring functionality and/or multiplexing functionality, thus being lower in cost than a SONET multiplexer.
