Equipment and Port Configuration System-wide Settings
5. Enable or disable the Sealing Current according to the system wide network definitions.
The Sealing Current is small electric current introduced by each modem in the High
Speed Link to "seal" the copper line from corrosion in humid environments. The Sealing
Current setting is applied to all working modems of the enabled HSL.
The Sealing Current default setting (ON/OFF) depend on the ML model; however, except
for drop-and-continue configurations (that can only be implemented on some ML
models), to enable the Sealing Current, the option should be ON only on the ML CO (and
disabled on the CPE). Enabling the Sealing Current on both sides may either prevent the
current (same polarity) or double the current (swapped tip/ring).
6. Alarm LED Indication - defines the behavior responses of the Alarm LED on the unit's
front panel.
Full - all problems invoke a LED alarm indication
Partial - only critical problems that require HW or SW replacement invoke a LED
alarm indication: HWFLT alarm indicated by STATUS LED and PROGFLT alarm
indicated by ALARM LED.
All other Alarms (less critical or port alarms) are indicated by the port LED
(available per ETH, HSL and MLP ports). In addition, alarms suppressed due to
Partial alarm LED configuration are not reported via GPO as well.
