A portable telecommunication test set, such as a telephone line butt set, with a web browser incorporated therein. A standard HTML (Hyper Text Mark-up Language) or WAP (Wireless Application Protocol) browser may be incorporated within the portable test set, allowing a network technician to access the Internet as well as other remotely-located sources of information to retrieve data and other useful technical information while in the field for communication network or telephone line maintenance, troubleshooting or repair. The test set may contain memory to locally store certain technical information, e.g., telephone line-specific data or circuit information, that may be retrieved and "read" by the built-in browser module when prompted by the network technician. The web browser may display the content of the requested information on a display provided on the test set. Line-specific (as well as manufacturer-specific) test information need not be in a manufacturer-dictated proprietary format, but, instead, may be in a generally available text format, e.g., the HTML format or the WML (Wireless Mark-up Language) format. Testing-related data may thus be supplied (as hardware or software plug-in modules) by a vendor other than the manufacturer of the test set.
