adsl2LineStatusLnAttenUs

Module: ADSL2-LINE-MIB

OID (symbolic): ADSL2-LINE-MIB::adsl2LineStatusLnAttenUs

OID (numeric): 1.3.6.1.2.1.10.238.1.1.1.1.15

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 diagnostics mode and initialization. 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 line attenuation is out of range to be represented. A special value of 0x7FFFFFFE (2147483646) indicates the line attenuation measurement is currently unavailable.

What is adsl2LineStatusLnAttenUs?

This read-only OID reports the total signal loss measured from the customer modem back to the headend in units of 0.1 dB (0–1270, or 0–127 dB physical). Comparing upstream and downstream attenuation can reveal asymmetric line problems, such as corrosion or damage on one conductor pair. For example, if upstream attenuation is 500 (50 dB) and downstream is 700 (70 dB), the return path is cleaner than the forward path.
