Cumberland County Commissioners Sign Key Agreement to Begin Portable Radio Exchange

Cumberland County, Pennsylvania- December 28, 2009 – On December 28, 2009 Cumberland County Commissioners approved a vendor agreement with Harris Corporation. The action sets in motion a major initiative to update the County's Radio Communications System. The initiative includes two major steps: a long awaited Federal Communications Commission (FCC) frequency reconfiguration and the release of a new generation of portable radios for emergency personnel throughout the County.

The FCC is reallocating frequencies to alleviate cell phone interference that occurs in 800MHz radio systems, which has been a recurring problem for Cumberland County and other emergency radio systems nationwide. The reconfiguration allows the FCC to move cell phones signals to a different range of frequencies which clears the 800 MHz spectrum for emergency communications.

The Department of Public Safety is deploying a new generation of portable radios to support police, fire, EMS and other emergency workers in the field. The Open Sky P7200 series portables will replace the P800 series portables. The communication system upgrade will include new software that has been extensively tested by the Commonwealth of Pennsylvania.

The Cumberland County Department of Public Safety has created an implementation team for the communications system upgrade that includes key staff from the Department of Public Safety; Harris Corporation – who acquired the Open Sky radio system from MA/COM; and L.R. Kimball - the County’s technical consultants on this project. The implementation team will authorize and coordinate training schedules to educate users on the operations of the new radios, identify target areas for replacement and formulate a schedule for the actual exchange process that will occur over the coming months. The team will also implement a quality assurance program for the radio system and expand efforts to generate feedback from system users throughout the County so that issues can be identified, addressed and corrected.

Are You Ready For The P7200 Series Exchange?

As our office continues to work towards preparing for the P7200 series exchange, we would like to remind all services that they may need to do some preparing for the exchange as well. We are encouraging all companies and departments to begin inventorying their portables, batteries, chargers and any other accessories that will be exchanged. While we do not expect you to collect items at this time, it is important that you know the location of all items. We understand it is easy to lose track of a battery or charger along the way, but any missing items MUST be located for the exchange process to occur.

V-TAC Management

We’ve all done it! You’re dispatched for the AFA to the nursing home, warehouse or business that you run, what feels like 100 times a year. Every time you get put in service in route or shortly after you arrive you quickly discover it is a false trip. Typically this all occurs on Fire 1. Typically we engage our V-TACs on such structures. What if the next time you show up, normal conditions from Side A, you and your team head in to investigate, still on Fire 1. This time you actually encounter a fire! You’re going to need a Talk Group! At this point though you are locked on to your V-TAC, no way easy to switch Talk Groups!

It is easy to say, “It’s just another AFA, no need for a Talk Group, we won’t be here long”. Would you send your firefighters in without airpacks on the standard AFA? No, because as responders we must always be prepared for the unexpected! So don’t send your firefighters in without a Talk Group.

When we were still using the low band system, it was alright to wait to request a channel, considering we had a limited amount of channels. Now that we are using the 800MHz system DPS is encouraging all responders to request a Talk Group on calls to structures where they know V-TAC’s are needed and there is potential for an emergency that may warrant the need of a Talk Group. Before you send your teams into the building, if Headquarters has not assigned a Talk Group request it! Switch to the assigned Talk Group on the mobile radio in the unit that will engage the V-TAC, and then engage the V-TAC.

V-TAC management is still a new concept in our county and something we all need to continue to train on. Looking for a topic for a company training night? Try V-TAC management! If you are interested in ideas or assistance for in house V-TAC training or have questions in general regarding V-TAC's please contact DPS!

We have briefly mentioned in previous blogs that there are several players that have been involved in the negotiation of the P7200 series portable release process and the band reconfiguration. Below you will find a list of these entities and what role they play in the process.

Cumberland County DPS

Harris - This may be a new name to some, but Harris Corporation signed an agreement to acquire Tyco Electronics Wireless Systems (formerly known as M/A-COM) in April of 2009. The Harris Corporation is now the provider of radio service and support for our 800MHz system.

Company Profile: Harris is an international communications and information technology company serving government and commercial markets in more than 150 countries. Headquartered in Melbourne, Florida, the company has annual revenue of $5.4 billion and 16,000 employees — including nearly 7,000 engineers and scientists. Harris is dedicated to developing best-in-class assured communications® products, systems, and services.

L. Robert Kimball - This consulting firm has worked with Cumberland County throughout the 800MHz radio project and will be handling the radio exchange process. As the actual exchange process will be tedious and very time consuming, Cumberland County has contracted with Kimball to assist in the exchange.

HACC - HACC has been contracted to assist in the delivery of training on the P7200 series portables.

Sprint/Nextel - Sprint/Nextel is the cell phone provider that operates on the 800MHz band and has been tasked with much of the financial responsibility during the band reconfiguration process. They are financially responsible for the costs associated with the P7200 series portable release and exchange among other things.

Transition Administrator - The Transition Administrator (TA) is an independent organization established by the FCC and comprised of Deloitte Consulting L.L.P., Squire, Sanders & Dempsey L.L.P., and Baseline Telecom, Inc. The purpose of the TA is to ensure a smooth 800MHz band transition nationwide. They will be responsible for establishing reconfiguration guidelines, specifying replacement channels, reviewing reconfiguration cost estimates, monitoring payment of reconfiguration costs, managing the relocation schedule, facilitating issue resolution, and administering the alternate dispute resolution process( The TA has been working with Cumberland County throughout the band reconfiguration process and assists and approves of contracts established between all involved parties.

Several questions have been posted on the blog and asked in meetings as to the status of the emergency button for the fire departments. The emergency button functionality is currently disabled on fire service 800 MHz radios. The decision to disable the button occurred due to events that occurred during training that caused DPS great concern. Prior to fire service transition to the 800 MHz radio system – a number of exercises were conducted on the training profile with the emergency button function enabled. During the exercises a number of accidental activations occurred while the current P800 series radios were is use. Individual activation results in a 10 second open microphone not allowing the assigned talk group to be used. At times there were multiple activations occurring at the same time. During these situations – the emergencies are queued or “stacked” - each resulting in ten second open microphones occurring one after another – again rendering the assigned talk group unusable for the duration until all emergency activations was processed by the system.

The functionality of vehicle repeaters also weighed in the decision process. Vehicle repeaters have two deployable methods in the radio system. One mode is called “XCOV” – this functionality allows scanning of talk groups for portables attached to the repeater; however – this mode only allows a maximum of eight portable radios to attach to the vehicle repeater. The second mode, and the mode used for fire service radios, is called “XCOV-TG”. This mode does not allow scanning by portables attached to a vehicle repeater but allows for a maximum of 30 portables to attach to a vehicle repeater – more appropriate for fire service applications than the “XCOV” mode. Since scanning of talk groups cannot be done on the “XCOV-TG” – default emergency talk group – where the emergency raised moves it to a pre-determined talk group – would not be supported on a portable attached to the vehicular repeater. The only practical way to deploy emergency function in “XCOV-TG” is by raising the operations talk group to emergency status allowing only the emergency activation and ten seconds of open microphone on the talk group. All other tactical communications is preempted and will remain preempted until all emergency activations are processed if more than one activation occurs at the same time.

These happenings were alarming to DPS and presented a situation in which responders may not have the ability to communicate during a true emergency. It is for these reasons and safety concerns the decision was made to not enable the emergency button function on fire services radios when the transition to the 800 MHz radio system occurred in July 2007.

It is important to note that DPS has not completely abandoned the idea of enabling the emergency button with the release of the P7200 series portables. We are looking for user feedback through the blog regarding this issue. What concerns do you have? What are you feelings regarding the button? How could we improve training, to avoid these multiple activations? Your comments and input are extremely important to us regarding this issue and we thank you in advance for your help!

As we are inching closer to the portable exchange process we thought the blog would be a great way to start to familiarize users with the new P7200 portables. While extensive training will still take place, we hope you find this introduction helpful!

Below is the P2750, which the average user will be utilizing, is the model without a the keypad function. The front face of this portable is very different from the P800 series. You will notice the display screen has been moved the the front face. The arrow keys allow the user to scroll through menu options on your portable. The "M" button acts as your "enter" button to activate selections. The SCN button toggles the Scan mode off and on.

The top of the P7250 will look some what similar to the P800 series. You will notice that the emergency button has been relocated to the top of the portable. The toggle switch for the V-TAC has been removed from the top of the radio as well as the A/B buttons that were used to scroll through menus. The display screen has also been removed from the top of the portable to the front. The LED radio status light can still be seen on the top of the radio, but is position on the front. The light is larger and more visible.

The side of the P7250 is extremely similar to the P800 series, the only major difference being the removal of the emergency button. The only other small difference is the scroll buttons are now located at the top of the PTT.
