Switch Segment 2-7 — Main Channel RTS/DCD Strapping

•Switch 2-7 set to up position – RTS/DCD transparent

•Switch 2-7 set to down position – RTS/DCD strapped ON

When switch segment 2-7 is set for transparent RTS/DCD operation, the main channel outbound RTS or DCD signal is ON only when a subchan- nel is active.

When switch segment 2-7 is set to the down position, the main channel RTS/DCD is strapped ON at all times.

Switch Segment 2-8 — Main Channel CTS Strapping

•Switch 2-8 set to up position –CTS strapped ON

•Switch 2-8 set to down position – CTS transparent

This switch is ignored when the main channel is connected to a DTE device.

If the 2185 is set for CTS strapped ON, CTS is sent to a contending sub- channel DTE device as soon as the main channel is available.

When switch segment 2-8 is set for transparent CTS, the CTS signal is not set to a contending subchannel DTE device until CTS has been received ON from the main channel device. See Figures 3-3 through 3-8.
