atmSuSystemCodingLaw

Module: ACE20-MIB

OID (symbolic): ACE20-MIB::atmSuSystemCodingLaw

OID (numeric): 1.3.6.1.4.1.164.12.4.1.9

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This attribute indicates the Method/Law for decoding/encoding the voice information. aLaw (2) is the standard Law for E1 links. uLaw (3) is the standard Law for T1 links. Coding law is applicable for all the ports in the system

What is atmSuSystemCodingLaw?

This OID specifies the voice encoding law (aLaw for Europe or uLaw for North America) used when the device encodes and decodes audio across all ports. Network engineers must set this to match the telephone network standard in their region to ensure voice quality and compatibility. For example, setting the value to aLaw (2) on a device in Europe ensures compatibility with E1 telephone trunks, while uLaw (3) is required for North American T1 trunks.
