Abstract: 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.
