c) reception of data. 11.3.2.2 TRANSMITTER AND RECEIVER CONTROL The HFDL physical layer shall implement the transmitter/receiver switching and frequency tuning as commanded by the link layer. The physical layer shall perform transmitter keying on demand from the link layer to transmit a packet. 11.3.2.2.1 TRANSMITTER TO RECEIVER TURNAROUND TIME The transmitted power level shall decay at least by 10 dB within 100 milliseconds after completing a transmission. An HFDL station sub-system shall be capable of receiving and demodulating, with nominal performance, an incoming signal within 200 milliseconds of the start of the subsequent receive slot. 11.3.2.2.2 RECEIVER TO TRANSMITTER TURNAROUND TIME An HFDL station sub-system shall provide nominal output power within plus or minus 1 dB to the antenna transmission line within 200 milliseconds of the start of the transmit slot. 11.3.2.3 TRANSMISSION OF DATA Transmission of data shall be accomplished using a time division multiple access (TDMA) technique. The HFDL data link ground station sub-systems shall maintain TDMA frame and slot synchronization for the HFDL system. To ensure that slot synchronization is maintained, each HF data link modulator shall begin outputting a pre-key segment at the beginning of a time slot plus or minus 10 milliseconds. 11.3.2.3.1 TDMA STRUCTURE Each TDMA frame shall be 32 seconds. Each TDMA frame shall be divided into thirteen equal duration slots as follows:
