NRZ DCE Operation

Part No. 24001157
Revision C
This section describes the function of the VersaMux-4000 control leads when the
NRZ interface is in the DCE mode (Mode parameter set to DCE).
DSR (DCE Ready)
When configured in the DCE mode, the DSR control lead is an output from the
VersaMux. The VersaMux asserts the DSR control lead at the beginning of the
activation sequence during power-up. It remains asserted during normal VersaMux
operation.
DTR (DTE Ready)
When configured in the DCE mode, the DTR control lead is an input to the
VersaMux. The VersaMux ignores the state of this control lead.
RTS (Request To Send)
When configured in the DCE mode, the RTS control lead is an input to the
VersaMux. The VersaMux ignores the state of this control lead.
CTS (Clear To Send)
When configured in the DCE mode, the CTS control lead is an output from the
VersaMux. The VersaMux asserts the CTS control lead at the beginning of the
activation sequence during power-up. It remains asserted during normal VersaMux
operation.
DCD (Received Line Signal Detector)
When configured in the DCE mode, the DCD control lead is an output from the
VersaMux. The VersaMux asserts the DCD control lead at the beginning of the
activation sequence during power-up. It remains asserted during normal VersaMux
operation.
KG-Resync
When configured in the DCE mode, the KG-Resync control lead is an input to the
VersaMux. The VersaMux ignores the state of this control lead.
