1. GENERAL
1.1 Introduction
The CIaPM—3 Paging Modulator module is an opn'onal plug-in component of the MT—3 Radio
Repeater System. This module provides digital and/or analog paging capability for Daniels MT—3
transmitters in all supported frequency bands.
The Cl-PM43 is designed for low power consumption, typically drawing less than 250 mA in steady
state. In its standard configuration. the CI-PM-3 uses an on~board frequency reference source
consisting of a 10 MHz OCXO with a standard stability of 0.03 PPM. For high stability applications
(such as Simulcast), the CI-PM»3 Paging Modulator may be configured to use an extemal high
stability reference source (Le. rubidium. GPS or WWV) with a standard stability greater than or
equal to 0.002 PPM. to discipline the on-board phase-locked loop OCXO oscillator. To ensure that
paging signals are the same relative to each transmitter. the Cl-PM-3 also incorporates a limited delay
compensation for the different link propagation paths between transmitters,
The Cl—PM-3 Paging Modulator supports both analog and digital paging formats. and can transmit
POCSAG and other 2-level modulation schemes at data transfer rates of 512. 1200, and 2400 Baudr
It can also be configured for use as a data repeater, whereby 2-level paging data is recovered. re-
shaped and then re-transmitted to an additional repeater/paging transmitter. The CI—PM-3 supports
4-level modulation formats in non-repeater mode (ie, in a base station paging transmitter application
only) at data transfer rates up to 1600 BPS. Each of the four modulation deviation levels can be
independently set. making the CI—PM-3 suitable for use in such pager signaling schemes as
Motorola‘s FLEXTM Paging Protocol.
Setup conditions are established via front panel switch settings. while internal jumper settings and
setup adjustments are easily accessible using the EC~96. 96 Pin Extender Card.
The CI-PM-3 Paging Modulator includes the following standard features:
- low power analog and CMOS control circuitry.
— extended operating temperature range;
— jumper selectable Repeater/paging transmitter configuration:
- on-board +/-(].03 PPM 10 MHz OCXO:
4 front panel selection of PLL OCXO using external high stability frequency reference:
- jumper and line selectable analog / digital paging configuration:
- connection for optional CTCSS encoder / decoder:
- balanced 600 Q / single—ended microphone input:
- selectable digital delay for Simulcast operation

Cl-PM-3 Paging Modulator Instruction Manual
2. THEORY OF OPERATION
The CI-PM-3 Paging Module circuitry can be divided into three main functional blocks: Paging
Signal Path. OCXO/PLL. and Configuration Options. The Paging Signal Path includes signal
conditioning circuitry which is used to level and edge-condition the incoming data signal, then band-
limit it for transmission. The OCXO/PLL circuitry develops a high stability 10 MHz reference signal
for the transmitter. The Configuration Options circuitry allows the CI-PM-3 to be configured for
paging/repeater operation, and includes compensation for propagation path delays in multiple
transmitter systems.
2 .1 Paging Signal Path
The CI—PM~3 can process both analog and digital paging signals. Paging control and data signals are
accessed w’a the DB-l5 front panel DATA/GIRL PORT 11 or through the 14 pin Control 2 [0
Connecwrs on the rear of the M-3 motherboard. Bi-level. RS-232 compatible 2—level digital paging
data is input through 11 Pin 1 (ALARM 8 control line). 4rlevel digital paging dam is input through
11 Pin 1 and 11 Pin 2 (ALARM 8 and ALARM 6 control lines). A clock input line is available
through 11 Pin 3 (ALARM 4 control line) for optional high-stability synchronimtion of 4—1evel
paging data.
Analog paging information is input through the balanced audio inputs. 11 Pin 9 and 11 Pin 10
(ALARM 7 and ALARM 5 control lines). The paging mode. either analog or digital. is controlled by
H Pin 5 (ALARM 2 control line). For applications which utilize both analog and digital paging
modes. 11 Pin 5 must be switched high for analog paging and switched low for digital paging. In
digital-only paging contigumtions. Analog/Digital Oven'ide shunt jumper JU4l-B must be installed.
Analog and/or digital TX Pl'I‘ is input via J 1 Pin 7 (ALARM I control line) for base paging
transmitter applications. and is generated inwmally from RX A or RX B COR for paging/repeater
applications.
2. 1 .l 2-Level Digital Paging
For 2-level data. front panel switch SW2 must in the NORM position. Level Select jumper JU23
must be in the 2/4ALVL (A) position and 11 Pin 4 (ALARM 3 control line) must be held low.
Altemately. if the paging system will be processing 2-level data only. 27LvV4-Lvl Mode Override
jumper JU42 can be in the Z-Lvl (B) position and the control line left unconnected. Data is input on
H Pin 1 (ALARM 8 control line). routed through Dam Input jumper JUSvA to RS~232
Driver/Receiver U3. dien through the normally made contacts of Digital Switch Ullb to Data Delay /
Bypassjumper JU36. The data signal is then routed through U9a to Ul2 where it is reshaped (edge—
conditioned). If the binary polarity of the data signal is to be inverted (ie. a logic ‘l' processed as
negative deviation. and a logic ‘0' as positive deviation). it is routed through U12d and 2-Lvl
Polarity Select jumper JUl—B (inverted). Otherwise it is routed through UlZc and 2-Lvl Polarity
Select JUl-A (normal). The data from Ul2 controls digital switch U9c which switches between the

respectively. The output of U9c passes through UlOa which is normally closed for 2-level signals.
and through U7b which is normally closed for digital signals. to input buffer U14a of the 6»pole
Butterworth Filter comprised of Ul4b. U14c and U14dt The output of the Butterworth Filter is
low-pass limited to 3400 Hz. and is sent to TX A and/or TX B DIR MOD (band pass) inputs via
UISa and U15b. R23 adjusts the band pass signal level, The output of the Butterworth Filter is also
normally routed via X0 Polarity Select jumper JUS‘A (normal polarity) to U15C and then through
UlOb which is normally closed for digital signals. to the X0 SELECT jumper JU6. The XO
SELECT jumper is normally installed in the normal (A) position, selecting the on-board 10.03 PPM
OCXO. The signal is then buffered (if no external REF LN signal is used) or summed with the PLL
correction signal (if an external high stability REF IN signal is used) by U16c and then input to the
MOD VP of the on-board OCXO.
w: Position B of the XO SELECT jumper selects the MT-3 transmitter’s +/-1.0 PPM 9.6 MHz
VCXO in lieu of the on-board 10 MHz OCXO. Use of this option requires reconfiguration
of the MT- 3 Synthesizer and may require that the X0 Polarity Select jumper IUS be installed
in the B (inverted) position if the VCXO has a negative slope An external +/- 0. 002 PPM
high stability reference signal cannot be used in this configuration
2.1.1.1 Self Test Circuitry
With front panel switch SW2 in the SETUP position. 8 VDC is switched to the control input of
switch Ulla andUlld. Ulla applies 8 VDC to the square wave symmetry adjustment R70. Ul 1d
enables the square wave generator U17c. Switch SW2 also places a GND potential on the control
input of square wave frequency selector. U7c. disabling it and switching R72 out of the feedback
circuit of U17c. Switch SW4 controls the output of oscillator U17c such that with switch SW4 in
the Data “1" position. a binary “l” is output from U17c and with switch SW4 in the Data “0"
position, a binary “0" is output. With switch SW4 in the “cenne” position. R41 is placed in the
feedback circuit of U17c through Ulld. causing U17c to oscillate at approximately 600 Hz. The
symmetry of the square wave signal produced (Let. the width of the positive going pulses as
compared to the width of the negative going pulses) is adjustable by R70. The three signals. binary
“0". binary “l" and the 600 Hz square wave, are switched through front panel switch SW3 to set up
the 2 and 4-Level positive and negative deviation levels (R3. R4, R5 and R6) as well as the band
pass gain (R23).
2. 1 . 1.2 Data Indicator Circuitry
With front panel switch SW2 in the NORM position. voltage follower Ul7b buffers the data signal
at the output of Ul lb and prior to the input of U9a. When an alternating binary signal is present on
J 1 Pin 1. the detector circuitry comprised of C46. R49. D8. R7l and C47 develops a DC voltage on
the control input (Pin 1) of switch Ulla. Conversely. zero voltage will be developed at this point
for uconstanr binary “0" or constant binary “".l This control signal causes Ulla to switch 8 VDC

to the square wave generator Ul7c and the square wave frequency selector U7c. Switch U7c places
R72 in parallel with R4l in the feedback circuit of Ul7c through Ulld. causing Ul7c to oscillate at
approximately 10 Hz. This signal causes the front panel DATA indicator. LEDZ. to flash at a rate
discernible to the naked eye.
2.1.2 4-Level Digital Paging
For 4‘level data operation. front panel SW2 must be in the NORM position, 2-Lvl/4-Lvl Mode
Override jumper JU42 must be in the A position. and Level Select jumper JU23 must be in the
2/4-LVL position with 11 Pin 4 held high or left unconnected. 4-level paging data is represented
using two data bits; input on pins 1 and 2 of front panel DATA/CTRL PORT J 1. Each of the four
possible bit combinations corresponds to a deviation level setting (refer to Table 46). An optional
clock input line is provided through 11 Pin 3 for 4-level signal synchronization. 4-level data is input
on 11 Pin 1 (ALARM 8 control line) and 11 Pin 2 (ALARM 6 control line). The 2 and 4-level input
is then routed through driver/receiver U3. through the normally made contacts of digital switch Ul lb
and U1 1c to the inputs of digital switches U9a (through Data Delay/Bypass jumper JU36) and U9b,
Data is also routed to the inputs of D Flip»Flop UlS. If a synchronizing clock signal is used. Clock
Enable jumper JU46-A is installed and the clocked outputs of U18 are switched through U9a and
U9b. Data is then input from U9a and U9!) to UlZc and UlZe. UlZc and U12e reshape the data
signals and the outputs are then routed through 2-Lvl Polarity Select jumper jumpers IU l-A (normal
polarity) and 4-Lvl Polarity Select jumper JU2-A (normal polarity). or through UlZd and U l2f and
then jumpers lUl-B (inverted polarity) and lU2-B (inverted polarity). The data signal from
U12cIU12d. representing Bit 0 of the 4-level data signal. is used to control digital switches U9c and
U9d, which switch between positive and negative deviation settings of the modulated signal as set by
R5/U 13C, R6U13d. R3/U13a and R4U13b. The output of U9c or U9d is selected by UlOa based
on Bit 1 of the 4-level data signal from UlZdUlZl’ through U7a. The output of UlOa is passed
through U7]: and follows the same path to the VCXO and OCXO inputs as the 2-level data.

2.2 OCXO/PLL
The main component of the OCXO/PLL circuitry is the 10 MHz Ovenized Crystal Oscillator
(OCXO). which provides the (standard) +/-().03 PPM stability reference signal to the front panel
REFERENCE INPUT of the MT-3 Transmitter, This circuit may also be configured to phase-lock
to a GPS or WWV referenced high Stability 10 MHz signal via the front panel REF IN SMA
connector to generate a higher stability reference signal of +/-0.002 PPM.
2.2. 1 Standard Frequency Reference
When the on-board OCXO is used as a stand-alone +/—0.03 PPM frequency reference. front panel
FREQ REF switch SW1 is set to the INT position. The cenue frequency of 10 MHz is factory—
adjusted via R82 which sets the output of voltage follower Uloc. It is HIGHLY recommended that
this adjustment NOT be altered. Uloc also, buffets the modulating digital paging signal routed
through X0 Select jumper IU6—A, The output of the OCXO is buffered by 50 0 gain block U19, to
the front panel REF OUT SMA connector. where it is then connected via 50 Q coax cable to the
REFERENCE mPUT SMA connector on the front panel of the MT-3 transmitter.
2.2.2 High Stability Frequency Reference
When a higher stability paging signal is required (i.e. for Simulcast operation). an extemal GPS or
WWV referenced signal is input via the front panel REF IN SMA connector. To enable the on-board
PLL circuitry. PLL Power Enable jumpers JU37 and JU39 must be installed and front panel FREQ
REF switch SW1 must be set to the EXT position. The input reference signal is buffered by 50 9
gain block UZO. is level and edge-conditioned by UZlb and U25a. then input as the reference to
Ultmhigh Speed Phase/Frequency Discriminator U4. The second input to U4 is the on-board OCXO
output which has been level and edge-conditioned by U21a and U25b. The output of U4 is a pulse
train of digital error signals with a duty cycle proportional to the phase difference between the
reference and OCXO signals. This pulse train is filtered by the second-order passive RC low-pass
filter comprised of R85, R84 and C36 for analog paging signals (short time constant). or R42. R28
and C36 for digital paging signals (long time constant). The selection of long or short time constant
filter is made through digital switches UlOc and UlOd based on the condition of DATA/VOICE
mode selection line ll Pin 5 (ALARM 2 control line). The output of the low-pass loop filter is
buffered by Uloa. level—adjusted by Ulob. summed with the modulating digital signal in Ul6c. and
connected to the modulating input of the OCXO. The output of the OCXO is buffered by 50 Q gain
block Ul9 to the front panel REF OUT SMA connector. where it is then connected via 50 Q coax
cable to the REFERENCE INPUT SMA connector on the front panel of the transmitter.

2-4 CI-PM-3 Paging Modulator Instruction Manual
The Cl-PM—3 has been designed for use in stand-alone base paging transmitter applications as well
as multiple-transmitter systems A multiple-transmitter system normally consists of a local base
station paging transmitter and one or more remote paging transmitters which regenerate the paging
signal and extend the paging coverage area. Optionally. one or more paging link repeaters may be
installed in the system to further extend the range and overcome such obstacles as extended distance
and/or mountainous terrain
Due to the complexity of ¢level signal regeneration. only 2-level paging formats are supported in
multiple-transmitter configurations. In any multiple-transmitter system. 2-Lvl/4—Lvl Mode Oven-idle
jumper JU42-B should be installed in the B position to select 2-level paging only.
2.3.1 Simultaneous Broadcasting (2 Level Paging Only)
When a paging system contains multiple transmitters. it is possible that the signalfrom one
transmitter may interfere with the signal from another. resulting in distortion that will degrade paging
reliability and intelligibility. A Simulcast system addresses this problem by ensuring that all paging
signals are of the same frequency and phase and that they are all transmitted at the same time. To
obtain identical frequency and phase at each transmitter. the on-board 10 MHz OCXO of each
CI-PM-3 can be phase-locked to an external reference signal (typically GPS or WWV disciplined)
via the front panel REF IN SMA connector (see Section 22.2. High Stability Frequency Reference).
To ensure that each transmitter in the system transmits at exactly the same time. the link paging
signals are delayed by a value which is proportional to the distance to the furthest transmitter in the
system, In this way. the propagation path delay for each link is accounted for. such that the
transmitter located the furthest from the base station has no delay applied to its paging signal. while
those located closer in have increasing amounts of delay.
The CI-PM-3 incorporates selectable digital delay compensation. thereby eliminating the necessity
for an external signal delay unit in most applications. To enable data delay. Data Delay Power
Enable jumpers JU38 and IU40 must be installed and the two jumpers of Data Delay/Bypass jumper
JU36 must be oriented in the DELAY position. The 2-level data output from Ul lb is routed through
JU36 to the input of the positive and negativeedge integrator circuitry and also to the data input of
U23. The positiveedge integrator is comprised of C60/51 and R99. U24a, U8d. and D11. The
negative-edge integrator is comprised of C52, U24b, U8e. USC and D12. U8f buffers and shapes
the combined edge pulses, which are then used to synchronize Programmable Counter U22 to the
data signal. The fundamental 2 MHZ output frequency of U22 is set by resonator X1 and is fine-
tuned by tuning capacitor C55. The output of U22 is a square wave which is a variable of the
fundamental frequency determined by jumper settings Data Delay Selection jumpers JU3 l. JU32 and
JU33. This square wave is used as the OSC input to Contact Debouncer U23. which generates a
corresponding delay on both the positive and negative going edges of the data signal. The jumper
settings of JU35. JU3 l. JU32 and JU33 will determine the total amount of delay applied to the data
signal to compensate for the propagation path distance (prefer to Table 4-3).

3.12 Simulmst Delay Setup
A typical Simulcast system is depicted in Figure 5-2. To correctly determine the differing
propagation path delays to each transmitter in a Simulcast system and compensate for them. signal
delays in both the transmission medium and the equipment must be known. For the purposes of this
manual. it is assumed that only Daniels MT-3 radio equipment will be utilized at each paging site.
and that each radio submck will be identically configured with Cl-PM-3 Paging Modulator modules.
Signal delays from the base transmitter to any paging transmitter are calculated as follows:
Dela." = tlLink) + new;
Where: tilink} = Propagation delay from Base TX to Paging TX
[154th = trim + tU’M) + tax)
I'M) = Delay through Receiver
trPM) z Delay through Paging Modulator
[(rx) = Delay through Transmitter
d = Dismce
The delay through the equipment at each paging transmitter site. t,w,.will be identical for each link.
and can therefore be eliminated from our calculations. As such. the only delay variable(s) of interest
will be the distance from the base transmitter to each paging transmitter. Since radio waves
propagate at or near the speed of light (3x10a m/sec). the delay calculation becomes:
Dem." z t(Link)
51 (km) X 3.33wec
or
= d(mi) x 5.3715“
DE Ei‘s’é‘f'i‘omcs ——————————————_-
Cl-PM-B Paging Modulator Instruction Manual FOG ID: HflVT-3-ISO-svos 3-5
For the Simulcast system depicted in Figure 5—2. the signal transmitted by PAGING TX #1 will not
be delayed. as this is the furthest site from are BASE TX. However. to ensure identical signal
processing characteristics at each site. the DATA DELAY circuitry of the Cl—PM~3 at PAGING
TX 141 will be enabled. but with zero delay selected. PAGING TX #2 will have its paging signal
delayed by a value proportional to the difference in distance between PAGING TX #I and PAGING
TX 442 to the BASE TX. The delay for PAGING TX ”2 is therefore calculated as:
De’aymink B) = (dam A) (70?!) - d(Linlr 3) (km)) X 3.33mec
Ur
= (damuflmi) - d{Ltnk5)(ml7)X 5~37I~LY€C
The delay calculations for any paging transmitter site in a multiple-transmitter system. with distances
measured from the site of interest back to the BASE TX, becomes:
DeIHWSue nflntererl) = (dfFurthe:1Sitz) (km) - d('Sitz oflnlerext) (10W) X 3.33usee
or
= (do—When Site) (Mi) - dthle u/Interest) (mi)) X 53714536
MM: Once the required delay has been calculated for a particular paging site. refer
to Table 4-3 delay settings:
1. Locate the DELAY (psec) value which is closest to the calculated value.
2. Set shunt jumpers JU31. JU32. JU33, and JU35 according to the JUMPER SETTINGS.
Wm: To set delay values other than those listed in Table 4—3:
1. Set the oscilloscope for 1.0 V/Div (vertical) and 0.5 its/Div (horizontal). Select channel 1 as
trigger input and Set Trigger Slope to positive.
2. Monitor the test data signal atTP9 on channel 1 of the oscilloscope and the output signal at TPS
on channel 2.
3. Adjust the oscilloscope for maximum horizontal display of the distance between the signals'
leading edges Adjust tuning capacitor C55 unfil the output signal’s leading edge on channel 2 is
delayed from the input signal's leading edge on channel 1 by the desired delay amount
Mole: NWT ' :
1. Set oscilloscope horizontal resolution to 5 uses/div.
2. install shuntjumpers JUSIB. JU32A. JU33A and IU35E (refer to Table 4—3).
3. Monitor TP9 on channel 1 of the oscilloscope. Monitor TP5 on channel 2 of the oscilloscope.
Adjust C55 for 8.8 horizontal divisions between the signals“ leading edges (8,8X 5 psec —
44 usec delay).
