AUTOMATIC LOCAL LAPB DEVICE CONFIGURATION METHOD AND APPARATUS

摘要

There is described a method of establishing operation of a local Link Access Protocol Balanced (LAPB) device operable as a data computing equipment device or a data terminal equipment device. The method comprises the following steps: receiving an initiator frame for an asynchronous balanced mode of operation directed to the local LAPB device from a remote LAPB device; if it is determined that the received frame information indicates that the remote LAPB device is operating as a data terminal equipment device, initiating operation of the local LAPB device as a data computing equipment device; and if it is determined that the received frame indicates that the remote LAPB device is operating as a data computing equipment device, initiating operation of the local LAPB device as a data terminal equipment device.
