Configuration61200051L1-1D ISU 2x64 Dual Port ISDN Service Unit User Manual 53Figure 6-18Flow Control Menu TreeData Format (asynchronous)A frame consists of a start bit, 7 or 8 Data bits, 0 or 1 Parity bit,and 1 to 2 Stop bits. The settings for Data Bits, Parity Bits, andStop Bits are available as shown in Figure 6-19.Figure 6-19Data Format Menu TreeTransmit Clock (synchronous data format)Selecting the Normal option causes the ISU 2x64 to be the syn-chronous DTE interface transmit timing source. Transmit data istimed from the transmit clock provided by the ISU 2x64. Withthe External option selected, the ISU 2x64 slaves to an externaltransmit timing source. The external clock is provided to the ISU2x64 by the external transmit clock signal at the DTE connector.3=CONFIG1=Netw. options2=DTE options3=Protocol4=Quick setup5=Security6=Remote Config1=Bit Rate2=Connector Type3=RTS Options4=CTS Options5=CD Options6=DTR Options7=DSR Options8=Flow Control9=Data Format1=Asynchronous2=Synchronous1=Hardware Flow2=Software Flow3=No Flow Ctrl3=CONFIG1=Netw. options2=DTE options3=Protocol4=Quick setup5=Security6=Remote Config1=Bit Rate2=Connector Type3=RTS Options4=CTS Options5=CD Options6=DTR Options7=DSR Options8=Flow Control9=Data Format1=Asynchronous2=Synchronous 1=Data Bits2=Parity Bits1=8 Data bits2=7 Data bits1=1 Stop bit2=1.5 Stop bits3=2 Stop bits1=None2=Odd3=Even3=Stop Bits
