Abstract
Method for performing a startup session to establish a communication session between a remote communication system and a central communication system. A start-up procedure is initiated by one of the remote communication system and the central communication system. The remote communication system selects one of a full duplex operating mode and a half duplex operating mode in response to a request by the central communication system. The remote communication system and the central communication system then exchange data representing a capability of at least one communication standard that is usable by each communication system to select a mutually compatible communication standard, so that the remote communication system can initiate the communication session using the acknowledged full duplex or half duplex operating mode.
