ISDN Switched circuit
models only
■ Select Initiate Data Service and choose the correct ISDN
bandwidth to use with this connection profile. In North America,
users are not guaranteed of having a 64k connection to their
destination, but only when 64k is not available from point A to
point B should 56k be selected. The Router automatically falls
back to 56k when 64k service is not available. It is advised to
select 56k when you know that the 64k service will fail. You
may also select Speech if your line is provisioned for this
feature and the call is within your local ISDN region. Selecting
Speech may save money, but it is not guaranteed to work
outside of your switch.
