PBX

Private Branch Exchange. An in-house telephone switching system that inter connects telephone extensions to each other, as well as to the external telephone network. A PBX controls the flow of telephone traffic through instruments such as paging systems and automatic callback and dialing.

PIN code

Personal Identification Number. To prevent unauthorized access to telephone lines, some PBX (Private Branch Exchange) systems require that a PIN code be entered when dialing to make a call or to send a document. Depending on the PBX system, the PIN code maybe entered before the number as a prefix, or after the number as a suffix. If your PBX needs a PIN code to connect to an outside line, you can specify the user data settings of the machine so that it prompts you every time that you dial.

Polling box

The polling box is used to store documents for polling sending in memory. The polling box holds the scanned document in memory until the other party polls your machine to send the document.

Polling transmission

Polling means one facsimile unit requests another to send a document. This is useful when the sending party, the party with the original document, is not in the office, but the document must be sent out. The receiving party dials the fax holding the original and requests that it be sent. In other words, the receiver always polls the sender.

Before using the polling feature, you have to set up polling boxes.

Pulse

See rotary pulse.

R

Regular dialing

Dialing a number with the numeric keys. Use regular dialing to dial a number that is not registered for any of the automatic dialing methods.

Relay broadcast

See relay sending.

Relay sending

Also called relay broadcast. You can send a document once to a fax in a distant location, then have that fax relay your document to several other destinations in the same area.
