Options: HDB3, AMI HDB3: In this line coding, the transmitter substitutes a deliberate bipolar violation when excessive zeros in the data stream are detected. The receiver recognizes these special violations and decodes them as zeros. This method enables the network to meet minimum pulse density requirements. Unless AMI is required in your application, HDB3 should be used whenever possible. AMI: Alternate Mark Inversion defines a pulse as a “mark,” a binary one, as opposed

The DCE/DTE strap is located near the DB15 connector on the top side of the board. The arrows on the top of the strap indicate the configura- tion of the X.21 port (for example, if the DCE arrows are pointing toward the DB-15 connector, the X.21 port is wired as a DCE). Reverse the DCE/DTE orientation by pulling the strap out of its socket, rotating it 180º, then plugging the strap back into the socket. You will see that the DCE/DTE arrows now point in the opposite directions, sho
