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
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).
13 Specify 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.
14 Click 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
