ABSTRACT:
There is disclosed a paged-mapped multi-line telephone communication system where a plurality of line selection keys can be paged to a central control module for an easier and more convenient operation. The operator has a view of all available lines and their status on various modules that are connected to the control module. The operator can select a line through a simplified pagination scheme. A set of lines represented on the auxiliary modules can be transferred to the control module where the operator selects the desired line by pressing the key corresponding to the line which was represented in the page transferred to the control module. To make an outgoing call, or to retrieve a call from another station from hold, the user would first depress the page key on the auxiliary module corresponding to the page or grouping in which the line representation resides.
