Devices and methods are disclosed for use in testing and evaluating aspects of a high speed communications network. In particular, a portable traffic checker for field use is provided that includes multiple sets of different types of communication links and is compatible with multiple protocols. One such traffic checker includes "test" and "monitor" modules having access to a data signal received by the traffic checker. The "test" module tests aspects of the communications network with a BER methodology, while the "monitor" module checks and reports on aspects of the data signal such as frame sizes, data rates, and data signal errors. Information obtained by the modules can be timestamped and stored in a log, and may also be uploaded through a communications port. Some information may also be displayed. Additionally, the traffic checker is switchable between the "test" and "monitor" modes and enables a user to select a data rate.
