2. It create objects that represent the cards discovered and that are going to be managed

3. It will raise errors if any of the slots are in an errored state (e.g. Mismatched card, invalid/ failed)

4. It will create the appropriate number of port objects for each line card discovered

5. It discovers the interfaces associated with each of the ports

6. It creates corresponding objects on the system. This object represents the equipment status of the container.

DECOMMISSION

Click the DECOMMISSION button or select DECOMMISSION from the Actions menu to change the status of the object from NORMAL to DECOMMISSIONED.

Active management will stop
All sub-objects will also be decommissioned
Polling on the selected object will stop.

Step 2 From the pop up menu select ADSL Line. The ADSL Line Status screen appears:

Step 3 The ADSL Line Status screen appears with the Line Status tab highlighted:

Figure 5-4: ADSL Line Status Screen (Line Status Tab)

The ADSL Line Status screen has three tabbed sections:

Line Status
Channel Status
ATM.

Line Status Tab

The Line Status tab is split into two sections: ATUC/ATUR and Common.

ATUC/ATUR

The ATUC (local end of the ADSL line) and ATUR (remote end of the ADSL line) section displays the following attributes:

SNR Margin (tenth-dB)

Displays the Noise Margin as seen by this ATU with respect to its received signal in tenth dB.

Attenuation (tenth-dB)

Displays the Measured difference in the total power transmitted by the peer ATU and the total power received by this ATU.

Output Power (tenth-dB)

Displays the Measured total output power transmitted by this ATU. This is the measurement that was reported during the last activation sequence.

Attainable Rate (bps)

Indicates the maximum currently attainable data rate by the ATU. This value will be equal or greater than the current line rate.

DMT State

Indicates the current state of the DMT transceiver. The current state can change dynamically.

The possible values displayed for ATUC are as follows:

Other: Unknown or other state.

PowerUp: DMT transceiver not yet configured.
