adsl2LineStatusSigAttenUs
Module: ADSL2-LINE-MIB
OID (symbolic): ADSL2-LINE-MIB::adsl2LineStatusSigAttenUs
OID (numeric): 1.3.6.1.2.1.10.238.1.1.1.1.17
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: 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. 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 currently unavailable.
What is adsl2LineStatusSigAttenUs?
This read-only OID measures the signal loss during active Showtime in the upstream direction, in units of 0.1 dB (0–1270, or 0–127 dB physical), and typically limits upload performance. High upstream attenuation explains slow uploads even when downloads are fast, so technicians check this to understand asymmetric speed complaints. For example, if upstream is 850 (85 dB) and downstream is 650 (65 dB), poor upload speeds are the root cause of slow outbound traffic.
