A wireless handset or other communication device includes a user interface implemented with a display and a number of select buttons. The display provides an array of identifiers arranged in rows and columns, with the identifiers corresponding generally to lines or functions of a communication system. The display also provides a status indication for each of the identifiers. A status indicator for a line identifier may indicate whether the corresponding line is in use by the handset user, in use by another system user, or idle, while a status indicator for a function identifier may indicate whether the function is activated or deactivated by the handset user. The assignment of identifiers to lines or functions may be in accordance with a mapping from a wired system, and the status information may be supplied to the handset from a switch of the wired system. The handset includes at least one row select button for selecting a particular one of the rows of identifiers provided in the display, and at least one column select button for selecting a particular one of the columns of identifiers. The selection of a particular row and column indicates selection of a line or function associated with the corresponding identifier. The display may be configured such that all of the identifiers and the state of their corresponding status indicators are visible to the user whenever the handset is on.

A cordless telephone set advantageously includes a wireless test mode accessible by a user for evaluating performance levels of operating parameters in the cordless telephone set in diverse geographical locations. When configured in a normal operating mode, the cordless telephone set provides normal wireless communications. When configured in the wireless test mode, the cordless telephone set provides audible and visual input to its user for use in determining a maximum acceptable separation distance for satisfactory communications between a telephone handset unit and its associated base unit in the cordless telephone set. This operating range determination for the cordless telephone set is achieved by providing a simulation of a recognizable tone, such as dial tone, to which a user subjectively listens while testing an application environment. At the same time, statistical readings of signal strength and voice quality also are provided in a display on the telephone handset unit while in this wireless test mode. The simulated tone and the statistical readings allow the user to quickly and easily correlate effective, usable operating range for the cordless telephone set.

An adjunct unit provides Incoming Caller Line Identification (ICLID) capability for a communication system. The adjunct unit interposed between the control unit and station sets of a communication system obtains ICLID from ringing central office lines and monitors signalling between the control unit and station sets to determine which stations are to receive the ICLID information. Using prestored database information the ICLID information can be used to obtain the calling party name for output to the station sets. The adjunct unit also outputs ICLID information to an application processor which stores calling records for the system.

Calling line identification adjunct for use with a communication system

A communication system includes a plurality of station sets each connected over two pair communication facilities to a control module. An adapter unit switchably connects an external data or voice device via a station set to either facility in response to a control signal from the control module. A data mode is established by sending a data mode request signal from the station set to the control module. An off-hook signal from a connected data device is used to request a data call. The control module signals to which facility the adapter is to connect the data call and outputs a unique visual on the data call facility. The control module prevents other calls from bridging onto or interfering with the data call. The system also permits a voice call on a facility to be converted to a data call on the other facility. Furthermore, a user can make a voice call over one facility while a data call is in progress on the other facility.
