choose either I or UI as the V.120 frame type. Leave this set at I

Enable Multilink PPP
The Enable Multilink PPP area lets you enable and disable the
modem’s Multilink PPP and dynamic bandwidth allocation features
and define cer tain parameters for Multilink PPP. For more
information,
see the “Using Multilink PPP” section on page 6-4.
Enable Multilink PPP. Check the Enable Multilink PPP box to turn on
the Multilink PPP feature. When Multilink PPP is on, the Netopia
ISDN Modem can combine two B channels to allow up to 128 Kbps
of data to pass through the ISDN line. You must enable this option
in order to use the Dynamic Bandwidth Allocation feature.
Dynamic Bandwidth Allocation. Check the Dynamic Bandwidth
Allocation box to turn on the Dynamic Bandwidth Allocation feature.
When Dynamic Bandwidth Allocation is on, you can initiate a phone
conversation after you have established a dual B channel
connection. When you initiate the phone conversation, the modem
disconnects one of the B channels and uses it for the voice call. For
more information,
see the “Using Dynamic Bandwidth Allocation”
section on page 6-7.
Second DN. (This option is only available for the Netopia ISDN
Modem Model 411.) If necessar y, enter a secondar y director y
number (DN) in the Second DN field. The Second DN number is the
second number of a destination you call. In most cases, you only
need to enter a second director y number if your telephone company
uses a switch other than an AT&T 5ESS switch or the destination
you are calling does not have its ISDN lines organized in a hunt
group. (A hunt group is a collection of phone lines that can be
accessed by the same phone number.)
