Abstract: A mobile device integrates a wireless headset with the housing of a mobile terminal. In an exemplary embodiment, the housing of the mobile terminal includes a fastener for mechanically connecting the wireless headset to the housing. When the wireless headset is mechanically disconnected from the housing, a speaker and microphone associated with the wireless headset interfaces with the mobile terminal via a wireless interface. However, when the wireless headset mechanically connects to the housing, the speaker and microphone associated with the wireless headset mechanically and electrically connect to the housing and operate as the speaker and microphone for the mobile terminal. A detector circuit included in the mobile device also determines the position of the wireless headset relative to the mobile terminal, and may automatically select a wireless or electrical interface between the wireless headset and the mobile terminal based on the determined position.

Abstract: A high speed data bus is time division multiplexed into multiple logical timeslot channels. Each of these timeslot channels is dynamically allocated to multiple endpoints within the data communication system. Each of these timeslot channels is shared from multiple communication sessions by the endpoints using a CMSA/CD methodology for allocating asynchronously usage of the timeslot channels. Additionally, network terminators may be used which may support multiple logical sessions by dedicating a timeslot channel to a network terminator and having other multiple endpoints coupled to this network terminator by way of the shared channel access protocol. Multiple copies of the shared channel access protocol procedure are located at a network terminator to handle multiple usages of the peripheral bus by the network terminator.
