Installation
SW1-5 − Receiver Dynamic Range (high- & low-speed modes)
SW1-5 ON = −10 to −43 dBm
OFF = +3 to −30 dBm
For a low receive signal level, set SW1-5 to ON (−43 dBm ). For short distances or to select a strong receive signal, set SW1-5 to OFF.
SW1-6 and SW1-7 − RTS-CTS Delay (low-speed mode only)
Switches SW1-6 and SW1-7 determine the duration of the RTS-CTS delay. Table 2-5 shows the RTS-CTS delays you can select using these switches.

SW1-8 − Anti-streaming (high- & low-speed modes)
SW1-8 ON = Anti-streaming active
OFF = Anti-stream inactive
Typically, anti-streaming is used in multi-point applications to prevent a malfunctioning slave modem from occupying the line indefinitely. When anti-streaming is active, the modem can transmit data for a maximum of 27 seconds before the transmitter turns off automatically. The modem then looks for an ON-to-OFF Request To Send (RTS) transition before proceeding with normal operation. Anti-streaming can be selected in either high-speed or low-speed mode.
