Term Definition
when the transmitter is remotely located, or when the transmitter is
part of a simulcast system.
Transmitter Link
Controller
A piece of equipment that governs how the link transmitter sends out
data. The transmitter link controller performs the same functions as a
transmitter controller, except it is interfaced to a link transmitter rather
than the paging transmitter.
Transmitter Zone
See Zone .
Trunk
A wireline data path between communications switching equipment.
On the paging terminal, a trunk describes an input/output port for
passing paging information.
Trunk Card
A dual-port telephone line interface for the paging terminal. A Zetron
trunk card can also receive RS-232 serial data and communicate with
remote equipment by way of a modem. The trunk card can be config-
ured to connect to a variety of telephone line types and data input
devices.
Tutorial
An educational lesson about the operating characteristics and
programming procedures for the Model 640 paging terminal. The
tutorial is part of the MCU software and provides a convenient on-line
method of learning about the paging terminal for first-time users.
2-tone
An older analog paging format. The 2-tone format supports tone and
voice pages. This format sends two separate tone signals that identify
the pager address. The 2-tone format is compatible with battery saver
transmissions and group calls.
UPS
An uninterruptible power supply that obtains standby power from
storage batteries to sustain system operation through brownouts and
blackouts.
Video Controller Card
An optional interface card included with the console kit. The video
controller card is installed in one of the open slots on the left side of
the paging terminal motherboard. The card provides a serial port that
connects to a monochrome display terminal for ZLINK access.
Voice Paging
1. A paging format that records a caller’s live voice message and
replays it out the speaker in the pager. Voice paging is most
commonly used in medical (hospital and nurse call) applications.
2. A feature Zetron prefers to call “PageSaver”. PageSaver actually
stores voice messages on to a separate hard disk for later retrieval
by the subscriber (like voice messaging). The PageSaver option is
only available on the 2000 Series paging terminals.
