Most of the features of the Model 64 can be fieldprogrammed by the user. These options are stored in a
database inside the Model 64. Programming can be done
from a touch-tone phone or using a video display terminal via
an optional modem/RS-232 interface.
Pager Programming
The Model 64 database is designed for simple and efficient
pager programming. Paging format tone plans, digital
function codes, radio zone steering, and pager capcodes are
programmed individually for each subscriber.
Temporary pager invalidation prevents access to a pager if
the person is unavailable or has not paid for service. When
an invalidated number is accessed, the caller hears a distinct
error tone.
Single command programming for a range of pagers and a
“copy user settings” command (with auto-increment of pager
capcodes) eliminates repetitive data entry.
Voice Pager Programming
One of four programmable voice time limits can be assigned
to each tone-and-voice paging subscriber. If the caller stops
speaking before the maximum time limit expires, the built-in
VOX circuitry terminates the message after a programmable
“quiet time” (typically 3 seconds). Note: Voice messages are
transmitted live from the telephone callers to the radio pager
subscribers. For high throughput applications that require
voice storage and forwarding, consider the Zetron 640 or
2000 Series Paging Terminals.
Display Pager Programming
The Model 64 supports the most popular digital display
paging formats. Display message limits are set automatically
when the type of pager is programmed for the subscriber.
Group Paging Option
A group of different types of tone-and-voice pagers and
mobiles can be alerted in sequence and sent a voice message
simultaneously when a single subscriber number is called.
Additionally, a display message can be sent to a group of
different tone-and-display pagers. This option provides 10
such groups that are each programmed with 2 to 10 pagers.
Groups can be extended to more than 10 pagers by using
pagers programmed with common pager addresses which
can be alerted as a single pager.
Database Preservation
A nonvolatile memory chip containing the system and
subscriber programming settings has a battery that preserves
memory for 4 years of power loss.
An optional RS-232 card makes it possible for the Model 64 to
communicate with an external computer or dumb terminal.
External Display Terminal
The modem/RS-232 option allows the Model 64 to connect
to a terminal device either directly via an RS-232 port, or
remotely via a 300/1200 baud modem. User-friendly menus
guide the user through programming the Model 64. All of the
programming commands are accessible through the terminal
except for the voice prompt commands. DTMF programming
remains unaffected by the addition of this option.

ZCU Communication Software Option
The ZCU software allows a standard IBM PC compatible to be
used as the external display terminal, and can up/download
the database in the form of a standard ASCII file. Please see
the ZCU specification sheet for more information.
Call Counting Option
The Model 64 call counting option tracks the number of
pages per subscriber. This is useful for billing based on the
number of pages a subscriber receives. The call counts are
downloaded via the ZCU software. These counts can be
imported into the optional Zebra billing software, which
provides a full accounts receivable system tailored for radio
service providers. Please see the Zebra specification sheet for
more information.
The Model 64 can be equipped with an optional voice prompt card that gives verbal instructions to untrained callers,
instead of the standard beep and tone prompts.
The operator can record these messages in their own
language from any touch-tone telephone. High quality
recordings make the prompts easy to understand, unlike
some synthesized systems.
Typical voice messages might be:
1. Hello. You have reached a radio paging system.
2. At the tone, speak your message.
3. At the tones, key in your telephone number.
4. That number is not in service.
The talk-back option allows two-way communication between
telephone (land line) callers and mobile radio users including:
land line-to-mobile, mobile-to-land line, mobile-to-mobile,
and mobile-to-pager calling. The Model 64 supports simplex
and half-duplex radio stations with carrier or voice-operated
audio switching.
The Model 64 provides pulse dial and regenerated DTMF
dialing for mobiles equipped with DTMF keypads to make
mobile-to-land line calls and signal pagers or other mobiles.
Toll restriction can prevent mobiles from calling telephone
numbers prefixed by “1” or “0”. Even mobiles without DTMF
keypads can place telephone calls. By quickly keying their PTT
twice the Model 64 automatically dials a preprogrammed
A choice of interfaces guarantees compatibility with any
telephone system - central office or PBX. Up to three
telephone interface cards can be installed, which each handle
a separate line. There are two types of cards: Telco cards or
Dual cards.
Telco Cards
The Telco card handles DID, end-to-end, and DTMF Overdial
type lines. Up to three of these cards can be installed in a
system. However, if more than one telephone line is used and
any one is a DID line, the Dual card option should be installed.
Dual Cards
The Dual card handles telephone company DID lines (either
immediate or wink start), or PBX lines (either loop start, E&M
type I, ground start, or station). The Dual card connects to
two central office DID or PBX trunk lines, or one line of each
type. One of these cards can be installed in the system, and if
desired, an additional Telco card can be installed.
Line Types
Selector level (DID) input is most commonly used in RCC/
PCP service from a telco central office. The caller dials a
normal telephone number, and the last 2, 3, or 4 digits of this
number are sent to the paging terminal automatically by the
telephone company, selecting the particular subscriber to be
paged. A single DID line can handle an entire block of 100 or
1000 subscribers.
The Model 64 answers calls to other types of lines (end-toend, loop start, ground start, or E&M tie line) with a beep
tone. The caller then keys in the pager number using a touchtone telephone.
Dial Click Decoder Option
If the caller has a rotary (pulse-dial) telephone, the optional
dial click decoder card is required. Note: The viability of dial
click decoding depends on the type of telco central offices
serving each of the callers and the paging terminal. Consult
Zetron for specifics.
Tone-Only Call Storage Option
With the Dual card two callers on DID lines can access
the system simultaneously because the card’s own
microprocessor answers the DID line and stores the last few
digits of the subscriber’s phone number while another paging
call is already in progress. Tone-only calls are put in queue for
transmission when the radio channel is available.
Model 103 Paging Entry Station Option
The Model 103 provides direct access for entering voice
and numeric paging messages into the Model 64 paging
terminal. It is a small desktop device that has a manual
keypad, a gooseneck microphone, and an LED display. Up to
three separate entry stations can be connected to the Model
64. Please see the Model 103 specification sheet for more
Operator Override
Normally, while one caller is being serviced, the system
supplies ringing tones to other callers attempting to access
the system. In emergencies, a switchboard attendant can
override any call in process.
The Model 64 interface signals select radio modulation mode,
carry audio tones and voice, handle digital paging data,
provide push-to-talk keying, inhibit paging when the radio
channel is in use, and activate audio switching from two-way
mobiles. In addition, transmitter control signals are flexible
enough to connect to a wide variety of network and remote
transmitter controllers, simulcast controllers, or dispatch
consoles. The Model 64 is rugged enough to withstand the
rigorous environment of radio sites. Most installers co-locate
the paging terminal with the radio equipment and run the
telephone lines to the radio site.

Remote Transmitter Control
In situations where co-locating the paging terminal with
the transmitter is not practical, the Model 64 can operate
a remote transmitter through a control link such as RF,
microwave, or telephone. Control equipment at each end of
the link combines the audio, keying, modulation mode, and
digital data into a composite signal for transmission through
the link.
Zetron’s Model 33 Paging Network Controller can be used to
remotely control the transmitter(s) via a wireline, microwave,
or RF link. The Model 33 uses the industry standard Motorola
PURC® protocol. Zetron’s Model 66 Transmitter Control Unit
can be used in conjunction with the Model 33 to remotely
control the transmitter(s). Please see the Model 33 and 66
specification sheets for more information.
Zone Addressing
Wide-area paging systems can be designed to avoid
the expense of simulcast equipment. By arranging the
geographical paging area into zones that do not overlap, the
central paging controller can select each zone in sequence
and reach all paging subscribers.
Or if necessary, simulcast transmitters can be used. With
zone addressing, the Model 64 gives access to subscribers
in four different geographic radio zones. Each pager can
be programmed for zone coverage in any one of the four
radio zones. In addition, the zones may be sequenced for
transmission in any two of the four radio zones for even
greater coverage.
Pager Formats
Analog capable transmitters are able to handle conventional
tone and voice signaling such as 2-Tone, 5/6-Tone, 2805Hz,
and DTMF. Some display pagers also operate on analog
transmitters - HSC and Multitone. Newer pagers such as
POCSAG and Golay Sequential Code (GSC) type pagers require
true direct-FM FSK digital transmitters. Even though some
transmitters are designed for DPL/DCG signaling, they may
not be able to handle the unbalanced modulation of digital
paging data. Be sure to ask the transmitter manufacturer if
the radio is direct NRZ FM.
Mobile Channel ID
The Model 64 can be field-programmed to monitor activity on
its radio channel from mobile subscribers. Following activity,
the terminal transmits the Morse code station ID to maintain
FCC compliance.
The Model 64 can be rack-mounted or placed on a desktop.
Spare parts kits simplify maintenance and repair. An optional
DeadBolt surge arrestor can be installed to help prevent
damage to the terminal.
