3.2.2 System Configuration b Line Coding: HDB3 (default) Options: AMI, HDB3 The System Configuration menu looks like this: 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
