The present invention provides a wireless telecommunications system comprising an interface mechanism for establishing a wireless link between a central terminal and a subscriber terminal within said wireless telecommunications system. The interface mechanism comprises a radio port manager within the central terminal for configuring the central terminal to receive an acquisition request message from a subscriber terminal on a radio slot associated with the radio port manager, and a radio port slave within the subscriber terminal for receiving an invitation message inviting the subscriber terminal to acquire the wireless link on said radio slot, and for issuing the acquisition request message to said radio port manager. The radio port manager is responsive to receiving the acquisition request message to grant the subscriber terminal access to the radio slot.

[ What is claimed is:] [9.]9. A radio port manager for establishing a wireless link between a central terminal and a subscriber terminal of a wireless telecommunications system, the radio port manager being associated with a radio slot and being configured to be operable to configure the central terminal to receive from the subscriber terminal an acquisition request message transmitted on said radio slot, and, upon receipt of the acquisition request message, to grant the subscriber terminal access to the radio slot, the acquisition request message being generated by a radio port slave within the subscriber terminal upon receipt of an invitation message from the central terminal inviting the subscriber terminal to acquire the wireless link on said radio slot specified by the invitation message, the radio port manager is arranged to determine a transmission rate required by the subscriber terminal for said wireless link, and, upon receipt of the acquisition request message from the radio port slave, to issue a rate switch message to the radio port slave if the radio port slave is not using the required transmission rate, thereby to cause the radio port slave to configure the subscriber terminal to use the required transmission rate before re-issuing the acquisition request message to the radio port manager.
