System Status
System Uptime This field displays how long the GPON Device has been running since it last
started up. The GPON Device starts up when you plug it in, when you restart it
(Maintenance > Tools > Restart), or when you reset it.
CPU Usage This field displays what percentage of the GPON Device’s processing ability is
currently used. When this percentage is close to 100%, the GPON Device is
running at full load, and the throughput is not going to improve anymore. If you
want some applications to have more throughput, you should turn off other
applications.
Memory Usage This field displays what percentage of the GPON Device’s memory is currently
used. Usually, this percentage should not increase much. If memory usage does
get close to 100%, the GPON Device is probably becoming unstable, and you
should restart the device. See Section 18.4 on page 148, or turn it off (unplug
the power) for a few seconds.
Interface Status
Interface This column identifies the interface on the GPON Device.
Status This field displays Up when the interface has a connection and Down when it
does not.
Rate This field displays the connection speed of the WAN interface’s PON connection
when it is connected. This field displays the connection speed and duplex for a
connected LAN interface.
Registration Status
Account This column displays each SIP account in the GPON Device.
Action If the SIP account is already registered with the SIP server, the Account Status
field displays Registered.
Click Unregister to delete the SIP account’s registration in the SIP server. This
does not cancel your SIP account, but it deletes the mapping between your SIP
identity and your IP address or domain name.
If the SIP account is not registered with the SIP server, the Account Status field
displays Not Registered.
Click Register to have the GPON Device attempt to register the SIP account
with the SIP server.
The button is grayed out if the SIP account is disabled.
