A digital interface for a wireless communication system is provided with a reduced number of connectors. A first connector conveys a data signal between the radio frequency and the baseband circuitries. The data signal represents a digital baseband signal received or to be transmitted over the wireless network. The data signal is a multilevel data signal and conveys more than one bit of a sample of the digital baseband signal at a time. The radio frequency circuitry synchronizes the transfer of the data signal with a synchronizing clock provided by the baseband circuitry. The baseband circuitry controls the operational mode of the communication system via a control signal representative of command to the radio frequency circuitry. The control signal represents commands of various lengths thereby enabling fast transfer of critical commands.
