ABSTRACT:
A communication network (20) capable of providing a subscriber originated alert message to other designated subscribers (80B, 162, 164, 80C, 166, 168) in the network (20) which have been selected by the message originator (80A, 82). Both the content of the alert message and the designated recipients may be readily varied at will by the subscriber via a keyboard (82A) which is associated with a video display device (82B). The telephone type distribution network (20) includes a plurality of switch nodes (22-38) at different geographic locations which are interfaced with the various subscriber keystations (82, 160, 164, 166, 168) through keystation or terminal controllers (80). Each terminal controller has display control logic (304) including local display storage (310-318) for locally storing retrievable data displays (310-316) and alert message displays, (318) directed to that controller (80). Each keystation (82) has a locally storable control page containing message routing control signals corresponding to different subscriber designated keystation recipient groups, with each designated controller (80) having a unique address code in that group. These control pages are locally stored at the switch node (22-38) associated with that originating keystation with which the controller (80) is associated and may be varied in content by the originating keystation. Once a control page has been predefined, the originating keystation (82) may rapidly select different sets of keystation recipient groups for a given alert message. A keystation (82) may thus contribute retrievable data as well as alert messages and message routing data to the network (20) to facilitate rapid individually tailored information dissemination to individually tailored recipient groups.
