Parameter: Line Coding
Path: MCT1 Connector > Edit Logical Lines > Port Details > MCT1 Port
Parameters
Default: B8ZS
Options: AMI
| B8ZS
Function: Specifies a line coding method. B8ZS line coding replaces a block of eight
consecutive binary 0s with an 8-bit B8ZS code containing bipolar violations in
the fourth and seventh bit positions of the substituted code. In the receive
direction, the B8ZS code is detected and replaced with eight consecutive
binary 0s.
AMI line coding is also bipolar: a binary 0 is transmitted as zero volts and a
binary 1 is transmitted as either a positive or negative pulse, opposite in polarity
to the previous pulse. (When configured for AMI line coding, the MCT1 link
module remains synchronized upon receiving up to 45 consecutive 0s.)
Instructions: Select the line coding method.
