The Min Data Rate text field requires the amount of upstream bandwidth that ought to remain for data applications even if voice applications use the 
entire available upstream bandwidth. The value selected here needs to be smaller than the upstream bandwidth and is measured in kbit/s. 

The  WAN IP Configuration page is only displayed if Ethernet or 
PPTP has been selected to be the uplink protocol. It offers the 
following components: 

The  Assign automatically via DHCP radio-button selection 
switches to automatic retrieval of the WAN IP address from a DHCP 
server at the ISP/uplink. 

  

 DHCP referred to here is the one that runs on the 

provider’s side and not the Bizfon’s personal DHCP server. 

The  Assign Manually radio-button switches to the manual 
adjustment of IP settings. This selection requests the following 
parameters: 

IP Address requires the IP address for the Bizfon WAN interface. 

Subnet Mask requires the subnet mask for the Bizfon device WAN 
interface. 

Default Gateway requires the IP address of the router where all 
packets are to be sent to, for example, to the router of the provider.

The WAN Interface Configuration page may be used to modify the 
MAC address of the Bizfon. This might be necessary if the ISP 
(Internet Service Provider) requires a specified MAC address, for 
example, for authentication. This page offers the following 
components: 

MAC Address Assignment manipulation radio-buttons: 

• 

This Device turns to the default MAC address of the Bizfon. 

• 

User Defined requires user defined MAC Address. 

The  MTU drop down list allows you to select the maximum packet 
size on the Ethernet (in bytes). MTU is used to fragment the packets 
before transmitting them to the network. The MTU preferred value is 
dependent on the Ethernet connection. The default MTU size is 1500 
Bytes for Ethernet and 1400 Bytes for PPPoE. 

Please consult with your ISP administrator to get the corresponding 
settings.
