| Name | Data Type | Default Value | Qualifiers |
| Name | Data Type | Value |
| LineAttenuation | uint32 | |
| Description | string | Measured difference in the total power transmitted by the peer Modem and the total power received by this Modem. This value is measured in tenths of dB. |
| Gauge | boolean | true |
| PUnit | string | decibel * 10^-1 |
| Units | string | Tenths of Decibels |
| LineState | uint32 | |
| Description | string | Status indicates the current state of the connection (line). The property holds a bit map that describes the possible conditions. For example,
1) No Defect - There are no defects on the line;
2) Loss Of Framing - ATUR failure due to the inability to receive a valid frame;
4) Loss Of Signal - ATUR failure due to the inability to receive a signal;
8) Loss Of Power - ATUR failure due to loss of power;
32) Loss Of Signal Quality - Loss of Signal Quality is declared when the NoiseMargin falls below the minimum NoiseMargin, or the bit-error-rate exceeds 10^-7. |
| ValueMap | string | 1, 2, 4, 8, 32 |
| Values | string | No Defect, Loss Of Framing, Loss Of Signal, Loss Of Power, Loss Of Signal Quality |
| MaxDataRate | uint32 | |
| Description | string | Indicates the maximum currently attainable data rate for the Modem. This value will be equal to or greater than the current line rate. |
| PUnit | string | bit / second |
| Units | string | Bits per Second |
| NoiseMargin | uint32 | |
| Description | string | Noise Margin of this Modem with respect to its received signal, in tenths of dB. |
| PUnit | string | decibel * 10^-1 |
| Units | string | Tenths of Decibels |
| TotalOutputPower | uint32 | |
| Description | string | Measured total output power (in tenths of dB) transmitted by this Modem. |
| Gauge | boolean | true |
| PUnit | string | decibel * 10^-1 |
| Units | string | Tenths of Decibels |
