50CHAPTER 5: CONFIGURING THE ISDN LAN MODEM
■Use one B channel: When selected, one B channel is used to connect to this service provider.
■Add second B channel as required: When selected, the second B channel is added when the first B channel reaches a certain threshold. The threshold default is 60%. To change the threshold default, refer to “Changing Data Call Parameters” in Chapter 6. The second B channel is temporarily removed when you place or answer another call.
■Use two B channels: When selected, both B channels are used to connect to this service provider (that is, always use Multilink PPP). Note that this prevents another call, data or voice to be placed or received as there is no available bandwidth (that is, the second B channel cannot be temporarily removed).
13Specify the B channel rate or select TollMizer.
Leave the B channel rate set to 64 Kbps unless your telephone company and the locations to which you will be connecting only support 56 Kbps.
TollMizer makes a 56 Kbps data call over a voice circuit allowing you to save the typical cost difference between a voice and data call. Note that the destination you are calling must also support this feature (also referred to as Switched 56 Permissive or Data Over Voice). Check with your telephone company and ISP to make sure that they support TollMizer.
14Click Continue.
A call is launched to your ISP. A congratulations message appears when you successfully connect to your ISP. This verifies the correct configuration of your ISDN line and ISP connection.
This configuration covers the typical parameters needed to connect to your ISP. There are additional parameters for this ISP connection which have been set to a typical default. These parameters include Domain Name, Compression, NAT, and WAN Link IP Address. In addition, you can enter a second telephone for connection to your ISP. For information on these parameters and instructions for changing their default values, refer to “Editing Service Provider Profiles.”
