You can use the ThinkPad modem only on a public-switched
telephone network (PSTN). You cannot use a private branch
exchange (PBX) or some other type of digital telephone extension
line. If you connect the modem to a line other than PSTN, an error
message appears, preventing you from using the line. If you are not
sure which kind of phone line you are using, contact your telephone
company.
