2.20.1.2 MIR/CIR in BreezeACCESS
The CIR (Committed Information Rate) specifies the minimum data rate
guaranteed to the relevant subscriber. The MIR (Maximum Information Rate)
value specifies the maximum data rate available for burst transmissions, provided
such bandwidth is available.
Under normal conditions, the actual Information Rate (IR) is between the
applicable CIR and MIR values, based on the formula IR=CIR+k(MIR - CIR).
In this formula k is between 0 and 1 and is determined dynamically by the AU
according to overall demand in the cell and the prevailing conditions that
influence the performance of the wireless link. In some situations the minimum
Filter IP Address Ranges A table of up to 8 IP address ranges. These are the addresses to/from
which IP frames are to pass if the User Defined Address Only option
is selected in the User Filtering Option parameter.
The Range/Subnet column enables selecting whether the entry is
defined as a Range (Start and End Addresses) or as a Subnet (Start
Address and Net Mask). Double-click on a Range/Subnet cell to open
a drop-doen menu that enables selection between the two options.
To add a range/subnet to the list, click on the
Add button: a new line
is added to the table, colored light blue. Define the desired
Range/Subnet option, enter the Start IP and the End IP /Net Mask
(the color of the line will change to white). To add another range,
repeat the process. The color of previously entered addresses will
turn green. If you regret, select the relevant entries and click on the
Revert button.
To remove one or more addresses from the list, select the relevant
entries and click on the
Delete button. The color of the entries to be
deleted will change to red. If you regret, select the relevant entries
and click on the
Revert button.
To delete all entries, click on the Delete All button.
To change an entry, select the necessary cell(s) and edit its contents.
Actual changes in the device will take place only after clicking on the
Apply button.
DHCP Unicast Override
Filter
When the User Filtering Option is activated (other than Disable),
unicast DHCP messages are filtered out; therefore the unit cannot
communicate with the DHCP server. The DHCP Unicast Override
Filter option enables to overcome this problem. When enabled,
unicast DHCP messages pass, overriding the user filtering
mechanism.
