ISDN2e will work with most desktop PCs and Apple Macintosh computers provided they are either fitted with an ISDN PCI card or connected to a suitable Terminal Adapter. In either case, the connection must be correctly configured.

To use an Apple Mac with ISDN2e you will need a Mac-compatible ISDN PCI card or Terminal Adapter. You may also require additional software for dial-up applications such as internet access or remote access. Please consult your Apple Mac supplier for further details for your particular setup.

How do I connect my LANs using ISDN2e?

If you are connecting LANs (groups of PCs linked together by a hub device) together using ISDN2e you will need to connect the LANs to an ISDN device such as a router at each end of the ISDN2e line. If you are using a router, the WAN port should connect to the ISDN2e line and the U interface should connect to the hub device.

When do I need a digital switch/PBX?

How do I plug telephones into my ISDN2e?

An ISDN line is digital, so you can only plug digital phones directly into the RJ45 connector. An analogue device such as a conventional phone or fax machine requires an interface to convert the analogue signal to a digital signal. This could be a Terminal Adapter with ports for analogue equipment, or a PBX.
