POTS Support Guidelines

You can connect the following equipment to 652/654 POTS ports:

•Standard DTMF

•Answering machine

•Modem

•Group 3 Facsimile machine

•The 652/654 supports only good quality telephone equipment. Contact your local Vanguard sales representative for details on supported equipment.

•652/654 POTS ports are intended for use with telephone equipment only. 652 POTS ports are not intended to drive existing house wiring for telephone service. They are intended for use with standard desktop telephone equipment, and should not be connected to publicly regulated analog lines.

•Each 652/654 POTS port supports a Ringer Equivalence (REN) of two. This means the total REN of telephone equipment connected to each port cannot exceed two. Standard telephone lines have a REN close to one. Modems, facsimile machines, and main powered telephones may have a REN of 0.2. Therefore, you can connect from two to four devices to each POTS port, depending on the type of telephone equipment you are operating.

•Each POTS port is connected to the other. The main line, marked as such on the backplane, is connected between pins 3 and 4, while the second line is connected between pins 2 and 5. This arrangement enables the connection of a two-line telephone or an extension of both ports with a single four-wire cable.

Note

Some modems and telephones may use pins 2 and 5 for purposes other than connecting to a second line. Make sure the telephone equipment connected to the POTS port is a two-lead cable.
