Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

1 = A-law 3 = Mu-Law. Access: Offline. AC INI-Param: PCMLAWSELECT

What is acSysPCMLawSelect?

This OID selects the audio compression standard (either A-law used in Europe/Asia or Mu-law used in North America) for PCM voice encoding on the TDM bus. Engineers must match the board's setting to the telephone network or switch they're connecting to, or voice quality will suffer. Setting this to 1 means A-law compression will be used, which is the standard in most countries outside North America.
