Cabling problems: Rule these out first
If you’re unable to establish a connection with a remote network, first check that
the ISDN line is plugged into the Pipeline. Telephone companies report that this
is the most common cause of initial failures.
Another common problem is incorrect Ethernet cabling. The cross-over cable
provided in the Pipeline package can be used only in a direct connection between
the Ethernet adapter (or external transceiver) in the computer and the Pipeline. If
you are connecting the Pipeline to a 10BaseT hub, you must use a regular
10BaseT cable between the hub and the Pipeline, and between the hub and the
computer.
For Macintosh computers, sometimes the port you used to plug the serial cable
into the Macintosh doesn’t work. You can use either the modem or printer port in
the Macintosh. If one doesn’t work, try the other one.
