For Mac Users

1. Internet via ISDN at the speed of 64Kbps/128Kbps

1-1. Call Bumping

The USB ISDN TA supports the call bumping function. Users do not need to
set anything to enable this function which will run automatically. If there is an
incoming analog call and the line connection is at 128Kbps, the USB ISDN TA
will drop to 64Kbps (one B channel) to accept this analog call. Also if you
want to make a remote analog call and the line connection is at 128Kbps, the
USB ISDN TA will drop to 64Kbps (one B channel) to make this call out.
Once 128Kbps is dropped to 64Kbps (i.e. one B channel is dropped), you
may click on "2nd B On" for raising again the connection back to 128Kbps by
yourself.
