Abstract
An operator complex in which control signals relating to key lamp and alphanumeric display operation and key transition data are carried between the operator console and the PABX system on a multiplex highway or radio transmission link to permit virtually unlimited spacing between the operator console and the associated switching system. The operator console includes a send control system and a receive control system. The send control system detects valid key transitions and formulates a message concerning such detected key transmissions to be sent to the common control in the PABX. The receive control system receives messages from the common control indicating key lamp or alphanumeric display information and decodes these messages to effect selective control over the display.
