Information on your ISDN line
Zephyr Xstream needs to know some things about your ISDN line to work properly. Your ISDN
circuit consists of two digital “B channels”. Just like a regular telephone line, these channels
have telephone numbers so that you can send and receive calls. The Zephyr Xstream, as with
most ISDN equipment, refers to these channels as “lines”. Unlike regular telephone lines, both
"lines" might have the same telephone number assigned to them.
There are several different types of ISDN service. You must know what type you have. In
addition, ISDN circuits in the US and Canada will usually have Service Profile IDentification (SPID)
numbers. SPIDs, when used, must be programmed into the Zephyr Xstream. In rare
circumstances, US users may also need Directory Numbers (DNs) if the telephone numbers are
not incorporated into the SPIDs.

ISDN TIP!
European & Japanese users should disregard all references to SPIDs. Euro ISDN &
Japanese ISDN do not have SPIDs! If your equipment configuration requires MSNs, they may
be entered in the MSN/DN menu options in the TEL menu. MSNs are optional, would only be
used if another ISDN device is sharing the ISDN circuit with the Zephyr Xstream.
Here is a summary of what you need to know and a place to write it down. You may want to
make a copy of this page and keep it next to your Zephyr Xstream.
