METHOD FOR INITIALIZING A SET OF ISDN ADAPTER CARDS BEING PLUGGED IN A WORKSTATION OPERATING AS AN ISDN PRIMARY GATEWAY, AND APPARATUS

摘要

A method for initializing ISDN adapter cards installed within aworkstation having a main processor and an ISDN primary adapterfor connecting the ISDN adapter cards to an ISDN primarygateway. Each ISDN adapter card has circuits for handling atleast one B-channel, and a first processor associated withmemory storage. The ISDN primary adapter includes a secondprocessor associated with a second memory storage. In responseto the reception of a specific polling pattern transmitted toeach adapter card by the primary adapter, a pattern istransmitted to the workstation processor for requesting theloading of the second memory storage with operational codetransferred from the workstation to the ISDN adapter card. TheISDN primary adapter, in response to the request patternreceived by the main processor, transmits a second pattern viathe ISDN adapter card that transmitted the first pattern, sothat the main processor in the workstation and the processor inthe ISDN primary adapter recognize the ISDN adapter card thattransmitted the patterns to the workstation and to the ISDNprimary adapter as the master ISDN adapter card fortransmission of control information on the D-channel.
