An analysis device includes a connector, a display, a digital communication circuit and a processing circuit. The connector is configured to connect to a coaxial cable of a communication system, the communication system including a connection to a network employing internet protocol communications. The digital communication circuit is operably connected to the connector and configured to communicate information signals within the communication system via the connector. The digital communication circuit is operable to establish at least two types of connections through the communication system. The first type of data connection employs an internet protocol, while the second type of internet data connection employs a voice over internet protocol. The processing circuit is connected to the digital communication circuit. The processing circuit is operable to obtain diagnostic data relating to each of the first type of connection and the second type of connection. The processing circuit is further operable to cause the display to display information representative of the diagnostic data.
