Value Description
CRC-4 CRC-4 multiframe format
Basic G.704 basic format
Default
: CRC-4
NOTE: E1 ISDN span interfaces are normally configured for CRC-4 line framing.
Line Compand
The PCM compression technique used by the span interface(s) hosted by this resource group. This parameter, along with Line
Framing , Line Buildout and Line Encoding , defines the physical characteristics of the span(s).

a-law European a-Law ITU-T PCM encoding
Defaults
• Interface Type T1 - µ-law
• Interface Type E1 a-law
Line Encoding
The line encoding algorithm of the span interface(s) hosted by this resource group. This parameter, along with Line Framing , Line
Buildout and Line Compand , defines the physical characteristics of the span(s).
