Using Preset Mode (With Agc Control In The Gx2-Ea1000C*/* Only); Network Management - Motorola GX2 EA1000C Series User Manual

Operation
4. Allocate time for the AGC to adjust the RF drive level to the laser and to adjust the
levels at the nodes.
5. Apply the additional channel load.
6. Allocate time for the AGC to adjust levels to the new channel load.
7. Additional adjustments to the GX2-EA1000C*/* should not be necessary because
the node AGC maintains a constant per-channel level at the node output.
The benefit of using Preset mode with AGC for an increase in channel load is that you
eliminate the need to re-adjust levels to each fiber node in the field.

Using Preset Mode (with AGC control in the GX2-EA1000C*/* only)

Implementation using Preset mode requires AGC control in the GX2-EA1000C*/* but not
in each node.
To implement an increased channel load using Preset mode:
1. Operate the GX2-EA1000C*/* in Preset mode.
2. Apply the preferred initial channel load.
3. Allocate time for the AGC to adjust the RF drive level to the laser.
4. Apply the additional channel load.
5. With the GX2-EA1000C*/* in Preset mode, visit each fiber node in the field and
adjust the drive levels as necessary.
6. Additional adjustments to the GX2-EA1000C*/* should not be necessary because
the AGC maintains a constant total power level to the laser diode.

Network Management

The GX2-EA1000C*/* monitors selected parameters during operation and compares the
measurements to a table stored in NVM. This table defines high and low limits, as well
as the
STATUS
limit, the
STATUS
CM100B. You can use the network management system to further isolate fault
conditions.
Table 4 identifies the default alarm limits and describes the status LED indication for
given parameters.
