adsl2SCStatusSigAtten
Module: ADSL2-LINE-MIB
OID (symbolic): ADSL2-LINE-MIB::adsl2SCStatusSigAtten
OID (numeric): 1.3.6.1.2.1.10.238.1.2.2.1.15
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: When referring to the downstream direction, it is the measured difference in the total power transmitted by the ATU-C and the total power received by the ATU-R over all sub- carriers during Showtime after the diagnostics mode. When referring to the upstream direction, it is the measured difference in the total power transmitted by the ATU-R and the total power received by the ATU-C over all sub- carriers during Showtime after the diagnostics mode. It ranges from 0 to 1270 units of 0.1 dB (physical values are 0 to 127 dB). A special value of 0x7FFFFFFF (2147483647) indicates the signal attenuation is out of range to be represented. A special value of 0x7FFFFFFE (2147483646) indicates the signal attenuation measurement is unavailable. This object reflects the value of the parameter following the most recent DELT performed on the associated line. Once the DELT process is over, the parameter no longer changes until the row is deleted or a new DELT process is initiated.
What is adsl2SCStatusSigAtten?
This stores the actual power attenuation measured during normal Showtime operation (Unsigned32, 0-1270 in 0.1dB units) after diagnostics complete and data transmission begins. An engineer monitors this ongoing value to detect if the line quality degrades over time, which would indicate developing problems like moisture ingress or increased external noise. Example: if Showtime attenuation increases from 640 units to 720 units over a day, it signals potential line degradation requiring investigation.
