98 Crocus SHDSL G703 Chapter 5 User manual Step-by-step configuration 5.9 Configuring the interface specific attributes crocusShdslTtRpG703/g703/coding Use the coding attribute to set the G703 interface encoding mode. Possible values are: Default:hdb3 Range: ami / hdb3 Value ami hdb3 Description Alternate Mark Inversion is selected. This is a bipolar code with no zero substitution. High Density Bipolar 3 is selected. This is a modified bipolar code.With HDB3 encoding, more than three consecutive zeroes occurring in the data are replaced by a substitution word. This to ensure a high pulse density. Therefore, data links using the HDB3 code can carry data patterns with a low 1 density. Most of the G703 applications use HDB3 encoding. crocusShdslTtRpG703/g703/crc4Insertion This attribute is only relevant in framed mode. Use the crc4Insertion attribute to determine whether the CRC-4 (cyclic redundancy check) is recalculated before sending it to the interface. The CRC is used to check the data integrity on the G.703 connection. The crc4Insertion attribute has the following possible values: Default:auto Range: enumerated, see below Value auto disabled enabled Description In auto mode, CRC-4 insertion is …· • disabled if the data is unframed,· • enabled if the data is G.704 framed. CRC-4 insertion is disabled. CRC-4 insertion is enabled.
