Term Definition
Terminal Block
Adapter
An optional interface card for simplified connections to the radio
station and telco equipment. The terminal block adapter is part of the
installation interface assembly option and plugs easily into the rear
panel RJ21 connector. It splits the 50 signals into four 8-pin telephone
jacks and two 12-pin Wiedmueller connectors for the analog and
digital portions of the transmitter interface.
Terminal Emulator
A software communications program that mimics a dumb terminal. A
terminal emulator program can be used on the office computer to
interface with the Model 640 for ZLINK communications.
Throughput
The paging channel input and output efficiency. Throughput refers to
the ability of the paging terminal to accept, process, and transmit
pages in a timely fashion.
Tie Trunk
A telephone circuit that connects two PBXs. A tie trunk is generally a
leased line at a cut-rate.
Time-out
A specified time limit in which a certain condition must be met before
a default action takes place. For example, the maximum time a caller
is allowed between keying DTMF digits before the paging terminal
considers the page complete.
Time stamp
An attachment that indicates the current time. Each page is time
stamped as soon as it is received by the paging terminal.
Tip
One of the two signaling leads used in most telephone line types. Part
of the tip and ring audio pair.
Tone-only Paging
A page that only causes the pager to alert (beep, vibrate, etc.). A tone-
only page does not include a display or voice message to relay any
further information to the subscriber.
Touch-tone
Telephone push-button dialing. See also DTMF.
Traffic
1. The frequency, volume, and duration of calls on a radio system.
2. A plus (+) prompt command that displays a real-time log of
paging terminal activity.
Transmission
Broadcast of communications data over a specific frequency range.
Transmitter
A device used to send RF data to remotely located receiving equip-
ment. Transmitters can send data in a variety of frequencies, formats,
and power levels (determines range).
Transmitter Controller
A piece of equipment that governs how the paging transmitter sends
out pages. The transmitter controller is physically installed between
the paging input and the transmitter. The controller differentiates
between digital and analog transmission modes and demodulates FSK
signals from the paging terminal. A transmitter controller is required
when the radio station output of the paging terminal is not adequate to
drive the transmitter, when the transmitter is not PURC-compatible,
