acSysPCMIdlePattern
Module: AC-SYSTEM-MIB
OID (symbolic): AC-SYSTEM-MIB::acSysPCMIdlePattern
OID (numeric): 1.3.6.1.4.1.5003.9.10.10.1.2.3.2
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: Defines the PCM pattern applied to the E1/T1 timeslot (B-channel) when the channel is idle. Default: 0xFF if PCMLawSelect is Mu-Law 0xD5 if PCMLawSelect is A-Law Range = 0x00 to 0xFF. Access: Offline. AC INI-Param: IDLEPCMPATTERN
What is acSysPCMIdlePattern?
This OID sets the byte value (0x00 to 0xFF) that the board transmits in a TDM timeslot when no active voice or data is being sent. Network engineers configure this to ensure proper channel idle state and sometimes to aid troubleshooting by using a distinctive pattern. For example, setting this to 0xFF (all bits set to 1) is standard for Mu-law systems and helps distant equipment recognize the idle pattern correctly.
