Term
Definition
Voice Prompts
A voice message that guides a caller in using the paging system. Voice
prompts tell the user when and what type of action is appropriate. The
voice prompts are recorded at the Zetron factory, however, they can be
field-recorded for custom applications.
Voice Storage
The amount of memory available in the paging terminal for temporary
storage of recorded voice pages and system voice prompts. Note that
the Model 640 does not provide permanent storage of voice pages.
The message is stored only until it is transmitted, then it is perma-
nently purged from memory.
Warm Up
A pre-transmission period in which the paging transmitter is allowed
to fully power up and prepare to send data. The warm up period aligns
the transmitter for digital keying. The warm up is also referred to as
high reliability mode.
Watchdog
An emergency monitoring system that oversees the operation of the
paging terminal’s ZPAGE software. The watchdog expects to see a
reset signal at specified intervals. If the software fails and the
watchdog is not “kicked” at the expected time, the terminal reboots to
reestablish proper operation.
WATS (Wide Area
Telecom Service)
A long-distance telephone service provided by the telco for bulk-rate
billing. Usually toll-free business “800” numbers are referred to as
WATS lines.
Wink Start
A telephone signaling protocol that initiates a call with a current
“wink.” The wink consists of an on-hook condition followed rapidly
by an off-hook and another on-hook.
Zone
The geographic coverage region of a paging transmitter. In a paging
system that reaches several areas, each zone identifies a transmitter
and locale to which the subscriber can travel and still receive pages.
Zone Address
A label that uniquely identifies a transmitter coverage region. In the
Model 640, the zone addresses range from 0 to 15. The zone address
(node) for TNPP applications is generally a four-digit number.
ZLINK
Zetron’s communication software for linking into the paging terminal.
The ZLINK program is similar to DOS in format and actually
includes some useful commands from that operating system. ZLINK
provides advanced diagnostics and maintenance features for the
paging terminal. ZLINK has been rolled into the MCU program for
ease of use and convenience.
