Description |
This parameter specifies the line coding scheme for line transmission. The E1 link codes are classified into HDB3 and AMI. Generally, HDB3 is used. High Density Bipolar 3 (HDB3) has the DC characteristics with a transmission distance of about several kilometers. The T1 link codes are classified into B8ZS and AMI. Generally, B8ZS is used because only B8ZS can avoid the loss of clock signals. |
