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.
