On W-WAN networks (where charging is based on the amount of data transferred as
opposed to
time spent on-line), this parameter may be used to specify a data limit after which
the unit will create
an entry in the event log to indicate that this amount of data has been
transferred. For example,
if your monthly tariff includes up to 5Mb of data before you are
charged an “excess”, you might
set the Data limit warning level to 4000. This would cause the
unit to place a warning entry in the event log once you had transferred 4Mb. This event could be
used to trigger an email alert message, SNMP trap or SMS alert message.
Issue a warning event after
Enter the maximum data to be transmitted before a warning entry is generated in the
eventlog. You have the option to select Kbytes, Mbytes or GBytes via the drop-down box.
Stop data from being transmitted after
This parameter is used to set the maximum amount of data that may be transferred before
the unit will “lock” the interface and prevent further transfer. As with the Issue a warning
event after parameter it is used on networks where the tariff is based on the amount of data
transferred to help prevent excess charges being incurred. You have the option to select
Kbytes, Mbytes or GBytes via the drop-down box.
Reset the data limit on the x day of the month
If you wish to automatically unlock a locked interface at the start of a new billing period,
this parameter should be set to the appropriate day of the month (from 1 to 28). When this
date is reached the unit will unlock the interface and data transfer may resume. If the
parameter is set to 0, automatic unlocking will not occur and manual unlocking will be
necessary (by clicking on the Clear Total Data Transferred button on the appropriate
Diagnostics - Statistics > PPP > PPP n page. This parameter will also reset the statistics
for the Data limit warning level (kb).
The factory default does not include any DSL settings and so when the router is first
installed, the following text will appear.
“This DSL PVC is not assigned to any PPP interface

When clicked, this link will redirect the browser to the Configuration – Network >

From this page, select the desired PPP instance. The PPP instance.
