Private Line. Also known as a leased line. A service offered
by many telephone systems; provides an exclusive phone
circuit between two geographic points. Most fax machines do
not require a private line. See also PSTN.
Proprietary. Non-standard. In fax, refers to a fax feature
which works only in communications between same-branded
fax machines.
PSTN. Public switched telephone network; the most common
type of telephone lines and service in use, in contrast to
private or leased lines. Most fax machines provide fast,
reliable data transmission over a PSTN line, and do not need
a special or dedicated telephone line. See also Private line.
RCR. Receive confirmation report. An RCR is your assurance
that the document you transmitted was received. The RCR
prints after your transmission, identifying the receiving unit
and recording the date, time, transmission mode, number of
pages sent and the result. The RCR is available only when
your fax machine transmits to another fax machine of the
same make and model. See also TCR.
Receiver ID. See Station ID.
PBX (or PABX). Private branch exchange; privately-owned
telephone equipment serving a particular building, business
or area. Many PBX systems use digital transmission lines
which, unlike more common PSTN lines, are not compatible
with fax machine use. The user should not connect a fax unit
to a PBX without first checking with the system manufacturer
or service representative.
PC Interface. Also known as the Multifunction Printer Option
(MFP). Allows you to connect a fax machine to a computer,
and work between the two.
Polling. Automatic transmission to a calling remote fax, or
reception of a document from a remote fax set for this
operation. Polling is convenient whenever a central unit must
receive information from one or several remote faxes. The
caller bears all telephone charges and prevents several remote
units from calling at the same time. In database or bulletin
polling, a remote fax machine polls a document directly from
the memory of another fax machine. (Regular polling
requires the document to be physically in the polled fax’s
feeder.) See also Secure polling.
