Letter from the President
What is in a
Name?
To most people we’re
just JPS. In 1998 we started
as the small business “JPS
Communications”. When
acquired in 2002, that was
still our official name as a
subsidiary, but we were typically called either JPS
Raytheon or Raytheon JPS. In April of 2016, I put
together a small group of investors to purchase the
company assets. When we reopened the doors, and
began operations once again as a small private
business, our name became JPS Interoperability
Solutions.
Why the name change? Leaving aside the legal
niceties, we’d morphed from a company with a wide
range of communications products into one with two
main lines, our ACU radio interoperability gateways
and our SNV analog voters. Influenced by our fit
with the mission of the Homeland Security
Department, JPS has sold to date somewhere over
9,000 gateways. We’ll never know exact totals again,
lots of records not making it through the transition.
Page 2
Issue 2017 – November/December
Because JPS originated the radio interoperability
gateway market (and believe me, in the early days it
was hard to get customers to understand the benefits
of our invention) and since the Public Safety Market
had largely standardized on the various ACU
gateways for its mission-critical inter-agency
communications, we naturally chose JPS
Interoperability Solutions, Inc.
What’s in a name? Often it’s intended to give
potential customers a hint of the main purpose of the
company’s business. In our initial incarnation,
including “Communications” in our name spoke to
the fact that we designed and supplied many, many
products, all used to enhance communications. In
fact, the company’s mission, from its founding in
1988, was, and still is:
To provide high tech solutions to communications problems
Why all this effort to explain our modest name?
Simple!! I want every reader and customer to know
we place our emphasis on Solutions rather than
Interoperability. While we intend to stay first in
interoperability, our overall focus is on practical, high
technology answers to all your communications
problems. I wish it were possible to prove this now
by revealing the myriad products and solutions
currently in Engineering (but they would kill me).
Yes, there are enhanced interoperability products, but
also the beginnings of new product lines!
You’ve read my opinions in previous JPS
newsletters, so you know that our intention is to
release a continuous stream of products to satisfy
communications needs. You’re also aware of my
opinion that interoperability now applies to voice,
data, text, and video. You know we purchased and
operate our Raleigh building and that Raleigh bounds
the Research Triangle Park along with Durham and
Chapel Hill. This area hosts an astonishing number
of colleges, providing a steady stream of qualified
technical talent. There’s no reason to limit our scope
in this environment, and this is reflected in the
ambitious array of new products in our current
Technology Roadmap.
So please - place the emphasis on “Solutions” -
and watch as our products flow out into the market.
This is fun!!!
Donald Scott – CEO/President
P.S. We are no longer just a supplier of superior
audio gateways, our technologies have developed
into fully IP integrated solutions that are scalable,
tactical, mobile, transportable, and fixed
infrastructure solutions. We seamlessly integrate
gateway communications interoperability into
expanded applications that include Radio over IP,
Voice over IP, Push to Talk over Cellular and local,
regional, and wide area communications systems
providing essential situational awareness.
Behind the Badge About the author – Lt. Joseph Pangaro
Joseph Pangaro is a retired Police Lieutenant
from the Township of Ocean, Monmouth County, NJ.
During his 27-year career, Lieutenant Pangaro served
in many capacities. After nine years as a patrol
officer, he transferred to the detective bureau where
he served for 12 years. During that time, Lt. Pangaro
prepared and executed hundreds of search warrants,
testified in many high-profile criminal court cases,
and excelled in criminal investigations including:
homicides, sexual assaults, drug crimes, fraud,
burglary, juvenile investigations, economic crimes,
vice crimes, quality of life crimes and other crimes of
violence. He has acted in undercover capacities and
worked with many local, county, state, and federal
agencies. Lt. Pangaro served as a sergeant in the

detective bureau, supervising a group of highly
motivated and active officers in the unit as well as the
“Quality of Life” unit.
In 2006, Joseph received a promotion to the rank
of lieutenant and supervised in the Patrol Division.
In January 2009, Lt. Pangaro’s responsibilities
expanded to include oversight of the day to day
operations of the patrol bureau as co-commander of
the division. Traditionally, this position is an officer
at the rank of captain. Lt. Pangaro graduated from
Fairleigh-Dickinson University, Florham, NJ
“Certified Public Manager Program” in 2008 earning
that professional distinction. In 2009, Lt.
Joseph is now the Director of Security for the
Manalapan/Englishtown School District. He is
President of the Monmouth County Security
Directors Association and on the Board of Directors
for New Jersey Narcotic Enforcement Officers
Association. Recognizing the need for police
training programs to be more current, hands-on and
simulate real-life situations, Joseph Pangaro, started
Pangaro Training. The many courses written by Lt.
Pangaro include, HyperDrive Narcotics
Investigations, Crisis Intervention, and Criminal
Investigation and Interview & Interrogation, all have
practical exercises including field and role-playing
components. Complementing the on-site training,
Joseph Pangaro is now developing a website, with
online training courses under the name Pangaro
Global.
“The 3 Pillars of Survival” / By
Joseph Pangaro CPM
Of the many topics near and dear to me; safety
and security are at the top of the list. After a career
in law enforcement and now as a person who teaches
safety and security programs to police officers,
school personnel, and people in the business
community, I see a great need for everyone to
consider what we do in our schools and work places
to prepare to effectively respond to danger and
violence.
We live in a day and age when an active shooter
or mass killer can strike anywhere at any time. When
we add in the potential for a lone wolf terrorist to
attack unexpectedly, we must understand the
potential for the danger we face individually and as a
society no matter where we live.
Getting the right mindset is critical if we are to
survive a violent event; taking advantage of the
technology and equipment that is available to us is
just as critical and something we cannot ignore or
avoid.
Getting the right mindset means understanding
the threats we face, and overcoming fear that those
threats create. It means taking pro-active actions to

Page 4
Issue 2017 – November/December
prepare ourselves, our families, co-workers, and
friends to react quickly and forcefully should
violence erupt. Once we accept this premise and
decide to get a survival mindset we have already
begun to increase our chances of survival during a
deadly event.
Next, we need to consider what actions further
enhance our odds at surviving a deadly encounter. I
have summed these actions up into Three Pillars of
Survival during a life-threatening situation like
facing an active shooter, mass killer or terrorist.
The first pillar is Preparation; mental and
physical. We must have a response plan and we must
practice our responses before we face danger. The
first pillar is personal, you must confront your fears
about being in a deadly situation and find a way to
overcome that fear; this is not easy so
how can we do it? One way we can
overcome our fear is to visualize
ourselves in a dangerous
situation and ask what would
we want to be able to do in
that situation? You do not
want the first time you
consider survival to be when
danger shows up at your door.
Preparation is all about thinking
ahead to figure out what to do
before it happens.
Would we be able to run and hide, do
we know where in our buildings we could hide? If
you do not know look around and find places now. If
you had to fight for your life, are you capable? If the
answer is no, then you must act to get in better shape.
Walk a little more, lift a few light weights to tone the
muscles; prepare your plan and yourself.
We should also demand this preparation from our
schools and businesses and talk to our families about
being ready where ever they are, and unfortunately
no age is too young. The Angels in Sandy Hook
were only 6 and 7 years old, the demons among us do
not care that they attack babies. We do not have to
scare the life out of little kids, but we can use age
proper conversations and practice to prepare them to
save themselves. All of us need to prepare, by
training, practicing, and educating ourselves on the
best ways to respond to danger.
The second Pillar of Survival is Communication.
We must be able to communicate danger to our co-
workers, students, and staff as quickly as possible
and we must be able to exchange vital information
during a violent incident.
There are many excellent products on the market
today that can offer that second pillar of protection
allowing us to communicate when it is
most important.
When it comes to
communication, the police
and other emergency
services people must also be
able to talk to each other.
Communication is the key to
the best response; and if we
are hiding or fighting for our
lives, if we can communicate to
the police then our chances of
survival grow exponentially.
There are products and equipment available
for use in emergencies that can offer that
instantaneous communication between us, the police,
and other first responders, even if we all have
different radios or frequencies. The electronic
emergency software programs available today are
just as amazing, allowing immediate messaging in
any emergency. Being able to exchange prompt
information in a crisis is vital to survival.
Page 5
Issue 2017 – November/December
The Third Pillar of Survival is Notification.
We must be able to notify the outside world that we
need help, and we must be able to do it quickly,
easily, and define the situation. During a violent
event, it will be hard to remember intricate code
words and use clumsy equipment. The equipment we
use must be ready in an instant and get the word out
to the police and others at once and in some cases
silently.
Fast notification of authorities like the police and
first aid units when violence strikes can mean the
difference between life and death. The police cannot
save us if they do not know we are in trouble.
Notification and Communication are the link in
our plan for survival and both are just as important as
the first pillar, Preparation. The programs and
equipment offered today are extremely reliable and
cost effective, and they give that instant and on-going
communication between those fighting for their lives
and those who would save us.
By seeking out and obtaining the equipment and
training I have talked about, and practicing our
responses in a realistic way with proper drills, we
cover the three pillars of survival thoroughly, and we
increase our chances of surviving the unthinkable.
These are scary conversations, ones I know we all
wish we did not have to engage in, but that is not the
world we live in today. To avoid satisfying the three
pillars of survival we invite tragedy into our lives.
Avoiding this conversation and the actions needed
only leave us unprepared and vulnerable. All of us
must get ready to react while at the same time hoping
we never must, but if we are aware and prepare we
may just survive when the violence comes.
I will end here with a simple thought that I
discuss when teaching people to prepare and survive
violence. The biggest obstacle to preparation is a
thought on our part, and the parts of those responsible
for keeping us, our kids, our schools, and businesses
safe - that thought is this - “It will never happen
here”.
That single belief, while it is based on statistical
fact to a large degree, is going to get people killed.
Even though the chances of us or our kids being in
the presence of a killer or active shooter is small, I
ask my audiences all the time this simple question-
“When and where will the next active shooter or
deranged mass killer strike?”
To this day no one can answer that question. If
they could I would go there and stop the violence and
be a big hero, but that will never happen because no
one knows when or where the next horrific attack
will come. The only thing we can do is prepare. The
three pillars of survival are our guide; learn them, act
on them and be safe. Let me know want you think.

JPS RoIP Bandwidth Details
Bandwidth Capabilities - General
description
The JPS product line uses RoIP to pass audio,
with RoIP, the IP connections on the DSP Module
in the 2000/5000 and T, the IP port on the NXU, the
IP port on the M, and the audio connections to
WAIS, all transport audio, COR, and PTT
information.
The benefit of using RoIP is that its interface to
communication equipment is by using current
network infrastructure. The above JPS products are
internet-focused applications exploiting VOIP
(voice over internet protocol) technology. The
advantages to incorporating these products into
existing communications architecture are:
• Enable low cost, extremely flexible radio
communication networks
• Multiplex voice audio and data over a
standard Ethernet network
• Cut the need for leased lines and
microwave sites, to end the requirement for
pilot tones and other in band signaling
• Facilitate centralized communication from
one computer
Bandwidth – What is Bandwidth
The term bandwidth describes the transfer rate
of data from one point to the next at any given time.
Bandwidth is a key aspect of networking and the
Internet business.
Bandwidth usage depends upon the
programming of the JPS equipment, or the
configuration to function, either, alone or as part of
a group. When calculating bandwidth usage of the
equipment, the programmer must consider TCP/IP
overhead, duplex operation, voice compression
settings and data settings. The JPS equipment uses a
connectionless-oriented protocol called User
Datagram Protocol (UDP) and, when using the RS-
232 serial data port, will make use of a connection-
oriented protocol called Transmission Control
Protocol (TCP). To understand the bandwidth
requirements of the equipment at any given time, as
a consumer, you need to understand each element of
the data flow process from end user to end user.
Page 12
Issue 2017 – November/December
What is a TCP / IP header?
The system used to support network
communications is the TCP/IP (Transmission
Control Protocol/ Internet Protocol) header. A
header is a bundle of relevant information to get the
data from point to point. To process data through
the Internet, TCP/IP is the disciplinary and the
single most important network protocol, without it,
you would not be able to transfer or receive data.
TCP/IP is a two-layer program. The top layer,
TCP, manages the assembly of messages for
transmission and reception over the Internet. The
bottom layer, IP, places the origin and destination
address on the packets of data. A TCP/IP
comparison can be to send a letter or package
through the postal system. You must box and tape
the package with certain packaging material, the
package must have a sender and receiver address,
and you must stamp and seal the package for the
postal worker to deliver. Once the package sealing
and stamping is complete, the postal center
coordinates and manages the delivery of the
package from start to finish. This is how TCP/IP
headers work.
Within TCP/IP, there is a protocol that needs to
decide how the information is going to get there,
like the way the post office decides based on the
delivery charge. UDP (User Datagram Protocol) is
the protocol that is comparable to sending mail by
air and TCP is the protocol comparable to sending
registered mail by truck. UDP protocol allows the
system to be more efficient, using speed vs. fail-safe
delivery. UDP is faster than TCP due to no error
checking and flow control responsibilities called a
checksum; thus, using less bandwidth than TCP.
Additionally, UDP will not constantly ask for a
confirmation that the package made it from sender
to receiver; while, TCP will keep trying to deliver
the package and continue requesting a confirmation
of the delivery until the delivery is complete, or it
simply times out. A fitting example of using UDP
would be for voice applications, such as, VOIP
(Voice Over Internet Protocol) and ROIP (Radio
Over Internet Protocol).
TCP (Transmission Control Protocol) is the
registered mail by truck, giving guaranteed end-to-
end reliable delivery service. Included with TCP is
an error checking and flow control process, which
makes the TCP process slower than UDP process,
using much more bandwidth. TCP protocol usage
is only when using the RS-232 serial data port. The
RS 232 data port is not typically in use; however,
when in use, the JPS equipment uses TCP protocol
to conduct and ensure the data transfer from end to
end. When this application is in use, it sends
commands from one system to another. At any
given time, the TCP data transfer will use 100% of
the bandwidth and is dependent upon the
acknowledgement of how much data is in use at the
end user. In addition to TCP protocol, the RS-232
serial port needs a BAUD rate. BAUD is a
measurement of the “signaling rate” which means
how fast the data transmission is per second.
BAUD rate is, for all intended purposes, the rate at
which each data packet travels per second. So, if
you have a BAUD rate of 300, then 300 data
packets (signals) send per second. You can
describe signal events as bits of information.
(NOTE: BAUD rate is different from data rate.)
Data rate measurement is in bits per second. Baud
port settings for the JPS products are 300, 1200,
2400, 4800, 9600, 19200, 38400, 57600, and
115200. Factory default setting is for 9600 baud.
Page 13
Issue 2017 – November/December
Checksum / Flow Control
The IP Checksum is an added part of the TCP/IP header. It is the error checking mechanism that is active
while using the TCP protocol. This mechanism ensures the data sent is in packets and gets to the destination.
This is only available using TCP protocol. The UDP does not have checksum in place for the intent of using
speed vs. total deliverability. TCP checksum is 4 bits of the TCP/IP header, which is part of the JPS equipment
total bandwidth calculation during RS-232 applications.
Full Duplex vs. Half Duplex Operations
In the JPS equipment, TCP/IP overhead of bandwidth is 20 to 25%, the actual bandwidth considers duplex
configuration. The JPS equipment allows for full or half duplex audio operations. Full duplex audio is when
users can send and receive audio simultaneously. A telephone conversation is typically full duplex. Half
duplex audio is when only one user at a time can talk at any given instance. Most radio communications are
half duplex capable.
Vocoder Operation \ Voice Compression Method
A vocoder operation is the ability to convert human voice or sounds into a digital signal and recreated to
sound like human sounds. Transmitting VOIP can consume a huge part of the network bandwidth. A solution
to effectively process VOIP requires converting voice information into digital signal processing algorithms to
compress the voice information so the signal consumes less bandwidth. We can describe algorithms as well-
defined instructions to process information. As a rule of thumb, the more voice compression, the less
bandwidth used, the less quality of voice output and vice versa, less voice compression, more bandwidth used,
better quality of voice output. In the JPS products, the options of voice compression at half or full duplex
configurations is the consumers decision.
The available voice compression settings are as follows:
• Method 1 GSM--13 Kbps, suitable for voice communications only (not recommended for tone
signaling). This method offers the greatest compression with reasonable voice quality. This is the
default setting for the JPS products.
• Method 2 ADPCM--16Kbps, suitable for voice or tone signaling. This method offers good voice
compression, but the voice quality is lower than other compression methods.
• Method 3 ADPCM--24Kbps, suitable for voice or tone signaling. This method offers less
compression than ADPCM 16Kbps, but the voice quality is better.
• Method 4 ADPCM--32Kbps, suitable for voice or tone signaling. Offers even less than Method 3
compression, but the voice quality is the best of the ADPCM compression types.
Page 14
Issue 2017 – November/December
• Method 5 PCM--64Kbps, suitable for voice or tone signaling. Providing the least compression, this
method offers the highest quality of all compression methods, but. You should use this method only if
your network offers low latency and throughput.
Voice Compression \ Tone Signaling
Another part of duplex, vocoder, and voice compression capability is tone signaling. There are many types
of tone signaling and the type used will directly decide which vocoder method will be best suited. Pure tones
do not occur with human speech. The JPS products offer some of these different voice compression methods to
support a variety of applications; however, these methods do not fare well with tone signaling. Tone signaling
is not a procedure that the vocoder design can handle. The vocoder design is to work on human speech. As a
rule, the lower the bit rate, the less likely a vocoder is to handle tones properly. Some examples of tone
signaling are frequency shift keying (FSK), pilot tone, EIA key tone sequencing, and dual- tone multi-frequency
(DTMF). A great advantage of using the JPS products for tone signaling is that they incorporate the only
known vocoder designed to work with FSK data. Electronic Industries Alliance (EIA) key tone sequencing is a
burst of high, low, and hold tones mixed with audio. The EIA key sequencing is in use when you wish to key
and control transmitters. A pilot tone is the simplest form of tone signaling. We typically associate the pilot
tone with COR applications in the voter and audio communication unit assets. It is a steady tone, showing an
Unsquelch condition for a radio, and does not fluctuate in amplitude or frequency. Sending two tones for a
specific period of time, the dual Tone Multi-Frequency is one of the most difficult keying methods, because the
DTMF decoders need to confirm receipt. In DTMF theory, the two tones are the ingredients that make a digit.
To prevent interruption of the dual tone relationships, we recommend only the two highest methods of vocoder
settings. To handle tone signaling, choosing the right vocoder method is key to successfully sending and
receiving tones from the JPS products. The recommendations for some common tone signaling, is to use the
following vocoder selections to ensure the tone recognition by the JPS products.
Page 15
Issue 2017 – November/December
Recommended usages for Tone Signaling:
Tone Type Vocoder Method
Frequency Shift Key (FSK)
PCM 64Kbps Method 5 (Highest quality of all compression) or ADPCM 32Kbps Method 4 (ONLY if the FSK data rate is not too high)
Pilot Tone Any ADPCM 16,24,32Kbps Method 2-4, or PCM 64Kbps Method 5
EIA Tone Key PCM 64Kbps Method 5 (if you try to use 32kbps Method 4, it may work but is not recommended due to its specific keying requirements)
Dual Tone Multifrequency
ADPCM 32Kbps Method 4 or PCM 64Kbps Method 5
“Keep Alive” Mechanism
A benefit of the JPS products are the ability to default to a “keep alive” setting. When there is no
transmission of audio, the unit will send a “keep alive” packet every four seconds to ensure the link is still open,
using little bandwidth.
Page 16
Issue 2017 – November/December
What is the Bandwidth Formula?
The bandwidth formula consists of all the elements previously discussed in this application note. Keep in
mind the protocol type, as well as, the type of duplex/vocoder method and the TCP/IP header baud rate.

TCP Protocol Bandwidth formula: (vocoder rate (x) 1.25) + (baud rate (x) 2) = B/W
(vocoder rate (x) 1.25) + (baud rate (x) 2) = B/W
Result: (128 (x) 1.25 = 160 Kbps) + (10 (x) 2 = 20) = 160 + 20 = 180 Kbps of bandwidth
The JPS products will consume approximately 180Kbps of bandwidth.
(vocoder rate (x) 1.25) + (baud rate (x) 2) = B/W
Result: (32 (x) 1.25= 40 Kbps) + (10 (x) 2= 20) = 40 + 20 = 60 Kbps of bandwidth
The JPS products will consume approximately 60Kbps of bandwidth.
For example, if the consumer has programmed the JPS product for
full duplex with a voice compression setting set for method 5--
128Kbps on the VOCODER (highest quality of voice or tone
signaling), and the RS 232 data port is in use, you would calculate
the bandwidth as follows:
Another example would be if the consumer has programmed the
JPS products for half duplex with a voice compression setting for
Method 4 ADPCM--32Kbps using the RS-232 data port, you would
calculate the bandwidth as follows:

UDP Protocol Bandwidth formula: (vocoder rate (x) 1.25) = B/W
(vocoder rate (x) 1.25) = B/W
Result: 128 (x) 1.25 = 160 Kbps
The JPS product will consume 160Kbps of bandwidth.
(vocoder rate (x) 1.25) = B/W
Result: (32 (x) 1.25) = 40 Kbps
The JPS products will consume 40Kbps of bandwidth.

In the same scenario but without the RS-232, if the consumer has
programmed the JPS product for full duplex with a voice
compression setting set for method 5-128Kbps on the VOCODER
(highest quality of voice or tone signaling), you would calculate the
bandwidth as follows:
Another example would be if the consumer has programmed the
JPS product for half duplex with a voice compression setting for
Method 4 ADPCM--32Kbps, you would calculate the bandwidth as
follows:

Frequently Asked Questions (FAQ’s)
From Benny Hillmann, Tech Support Engineer
All Equipment - When do I need a null modem cable
RS-232 serial devices can divide into two types:
• Devices that give control information are DTE (Data Terminal Equipment) devices.
• Devices that accept control information are DCE (Data Communication Equipment) devices.
In the "old days", the DTE devices were terminals and computers, while the DCE devices were modems.
The RS-232 standard specified that DTE devices would connect to DCE devices using a straight-through cable.
If you wanted to connect two like devices (DTE to DTE or DCE to
DCE) then you needed a null modem (crossover) cable. The PC is a DTE
device, and the NXU-2A and ACU-1000 are DCE devices.
For example, that is why you need a crossover cable for connecting
an ACU-1000 (DCE) to an NXU-2A (DCE).

ACU - My Radio False Keys Sometimes
Symptom: False Keying of DSP Module
• Cause:
o Possible extraneous RFI emissions present
• Solution:
o Eliminate RFI emission source
o Transit power of other donor radios too excessive; reduce enough to link to repeater
o Modify antenna placement
o Change COR Squelch Type to VMR
o Reduce COR or VMR sensitivity
When installation of a radio is in an environment with lots of RF emissions near the receiver’s frequency,
these emissions may cause the radio to Unsquelch inappropriately. Some radios have a greater tendency for this
problem than others. When the inappropriate Unsquelch occurs, any radios cross-connected with the offending
radio will momentarily send a loud burst of noise.
If any radio tends to key on noise (and it is not possible to rectify by reducing the RFI or altering antenna
placement), the best solution is to change that radio’s system interface to VMR Mode rather than to use either
Page 22
Issue 2017 – November/December
COR or VOX. In VMR Mode, the Interoperability System will ignore these inappropriate noise bursts because
the VMR will trip only during detection of human speech in the receive signal.
Any incident scene is likely to be a volatile RF environment because of the deployment of a wide range of
communications devices. This makes the on-the-fly optimization capability of the ACU-2000 very beneficial.
A quick switchover to VMR mode can easily be made by the ACU Controller or WAIS Controller when
changing conditions call for it.
SNV-12 - CIM SW3-1 TX Source Priority Selection
When in Duplex Repeat Mode, the voter can set up so that either Console TX audio or voted audio (Field)
will have priority when both are present. The selected priority audio is sent to the transmitter. When the unit is
in Simplex Mode (repeat or non-repeat) this priority decides whether the console will be able to break into a
voted message coming in from the field.
In earlier versions of the SNV-12 software, this feature was called “Simplex Mode Console TX Inhibit”.
This feature works the same when the unit is in the Simplex Mode. In Duplex Mode operation, new
functionality was added.
