Abstract
An integrated services digital network (ISDN) test set includes an ISDN transceiver, a supervisory control processor which is operative to cause the ISDN transceiver to controllably transmit and receive ISDN communication messages over a communication circuit, and an alpha-numeric message display through which messages associated with the operation of the ISDN test set are displayed. The test set keypad also includes a dedicated `ASSIST` key, that is selectably operated by the user, to cause the control processor to execute a user assistance routine, which accesses a contextual-based alpha-numeric database, whose contents are associated with and provide additional information of a displayed alpha-numeric message. This enables a test set user, regardless of training or experience, to be provided with information necessary to competently operate the test set and successfully test an ISDN line.
