DEEP TECH NOTE!

Amaze your technical friends with your voluminous knowledge of the Zephyr Xstream, ISDN,

and coding technology! Not necessary for the ability to install and use the Zephyr Xstream,

but this information might come in handy if you ever need to troubleshoot the system.

designed to be easily learned by Zephyr users. We will try to anticipate areas where the

differences might be confusing, and draw your attention to them.

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.
