NRZI option is reliable for bit stuffed protocols such as SDLC but is subject to failure in a BiSync due to the potential for insufficient bit cell transitions This is not a limitation on the DT 4000 hardware but rather a fact of the encoding itself The NRZI encoding on SDLC data streams is by far the most common variant of these protocols It is this NRZI encoding which is used on the isochronous LTS connections In order to use a DT 4000 port with recovered clocks it should be programmed with the protocol the line encoding the operation on the data the baud rate and the recovered clock Consider the following command port 1 prot sdlc baud 1200 enc nrzi dxe dce clk rcvd fill flag This command instructs the DT 4000 that the port is SDLC NRZI with recovered clocks The baud rate is required in order to properly recover the clocks from the data and must match the peer The dxe dce instructs the DT 4000 that it should control CTS from the peer DTEs RTS and not wait to send data The clkzrcvd instructs the DT 4000 that the clocks are to be recovered from the data rather than on a separate EIA lead Please note that this configuration would use the asynchronous DCE adapter i e the AG adapter The fill flag option is the default for an SDLC port and specification of the option is not required unless the port had been previously configured otherwise Suppose that the port is to be connected to a modem device operating in 2 wire half duplex mo
