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

Cops West Palm Springs Convention Center

Come see the new ACU-Z1 & RSP-Z2

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.
