Conferece Phones

The best way to tell is to consult the phone system’s documentation or – in a corporate environment – to call your company’s teleservices department. Here is additional information to help you determine the type of phone system.

Analog phones are used for public switched telephone networks – plain old telephone service (POTS). However, some private exchanges support analog telephones, fax machines, and modems. Look at the back of your telephone; if it says, “complies with Part 68, FCC Rules,” and has a Ringer Equivalence Number (REN), the phone and line are analog.

Digital telephone systems are usually found in corporate environments. Most PBXs (private branch exchanges) are digital. Signs that the phone and line are digital: phones with multiple function keys and/or multiple lines, the need to dial 9 for an outside line, no fax machines or modems connected directly to the phone line. Caution: if analog equipment is connected directly to a digital telephone system, it will not work, and the equipment can be damaged.
