| LABEL | DESCRIPTION |
| Administrator | Type how many minutes a management session (either via the Web Configurator or |
| Inactivity Timer | telnet) can be left idle before the session times out. The default is 5 minutes. After it |
|
| times out you have to log in with your password again. Very long idle timeouts may have |
|
| security risks. A value of "0" means a management session never times out, no matter |
|
| how long it has been left idle (not recommended). |

5.4 Transceiver
Click Maintenance > System > Transceiver to view your GPON Device’s current transceiver status and configure alarm thresholds. The optical SFP transceiver’s support for the Digital Diagnostics Monitoring Interface (DDMI) function lets you monitor the transceiver’s parameters to perform component monitoring, fault isolation and failure prediction tasks. This allows proactive, preventative network maintenance to help ensure service continuity. The values in the following figure are an example for reference only. See the table for details about the normal parameter ranges.

Table 7 Maintenance > System > Transceiver
LABEL | DESCRIPTION |
Current Value | This column displays the current status for each monitored DDMI parameter. |
|
|
High Alarm | Use this column to set the high value alarm threshold for each monitored DDMI |
Threshold | parameter. The GPON Device reports an alarm signal to the Optical Line Terminal (OLT) if |
| the monitored DDMI parameter reaches this value. |
