Positron needs to write a brief letter explaining that their equipment will make the City of Miami PSAP Phase 2 Compliant and briefly explain how this is accomplished. Response: Positron's Life Line 100 E9-1-1 controller supports 8, 10 and 20 digit ANI reception via multi -frequency ("MF") or Enhanced MF ("EMF") signaling from the serving E9-1-1 selective router. This provides support for non call -path associated signaling ("NCAS"), call -path associated signaling ("CAS") and hybrid approaches to delivering FCC Wireless E911 calls. Additionally, the Life Line 100 supports the NENA recommendation to assign trunk number 97 to repeat ALI requests. Your local exchange carrier employs a non call -path associated signaling approach to deliver Wireless E911 information and employs EMF signaling. This means that the wireless calls are delivered to your PSAP with a ten (10) digit ANI. This ANI is a non-dialable pANI that is used to perform the ALI lookup. The ALI contains the wireless information as provided by the wireless provider. This NCAS approach results in the call back number, cell tower/sector location and X,Y coordinates being delivered, as applicable, in pre -defined fields in the ALI stream. Your local exchange carrier presently employs NENA format 2.1 for data interchange, which is fixed length ALI format. Complete details of this format can be provided. From the call taker's operational perspective, Power 911 is capable of recognizing different wireless providers and compensate for limitations to the NCAS approach. This means that Power 911 can be configured to properly swap the pANI and call back number, which provides consistent treatment of all calls whether they be wireline or wireless. This wireless ALI format feature also allows for 1 button re -dial for wireless calls. Additionally, Power 911 fully supports repeat ALI requests to allow for updated Phase II information if provided by the wireless provider. Power MAP provides comprehensive treatment and display of wireless calls, which is detailed in the attached white paper — The Power to Respond — Mapping. Positron has hundreds of locations successfully receiving and responding to wireless calls across the nation, and provides rich value-added features such as the Wireless ALI Formatter described above. 2. Positron needs to explain how their equipment will interface with the existing CAD that the City of Miami PSAP curently utilizes. Via a serial port? Need brief explanation. Response: The CAD interface is located on one of the Power 911 IWS computers on an RS232C serial port (this can be any workstation computer or server). This CAD interface conforms to the NENA standard, and provides a CAD computer the position number and ANI/ALI information exactly as received from the ALI database.

Does it pass Ringing through it? Response: The Life Line 100's SIG Module, under NIM Module control provides ring generation. Note however that the method for ringing in a PBX configuration is as follows. • With a NIM Module set to its recommended setting (Type 2 — CO Line), it provides battery voltage to the PBX when a call is present. • The PBX in turn sends a digital "ringing" message to the PBX set (in this case the CaIlMaster VI connected to the Power 911 workstation). • The PBX also provides the off -hook condition back to the Life Line 100's NIM Module. 4. There was a brief mention of an RJ11 jack to be located at each E9-1-1 Position but I did not get what was needed or if this was an action item. Perhaps you can recall the conversation and can expand on what is the customer needed on this... Response: The RJ11 jack refers to the phone line wall outlet. One jack per position is required for the CaIlMaster VI. In the case of the Fire Department, an additional phone jack per position will be required to support their existing 8434 phones, in addition to the CaIlMaster VI. 5. The need to mirror Fire's existing 8434 phone sets and the CallMasterVl sets from the Life Line 100. This was addressed on the conference call last month by both Positron and Avaya and I forwarded the minutes to everyone last Thursday. Furthermore, the Expanets/Avaya folks (Monika Martins) mentioned that bridging the 7 CaIlMaster VI's and the 7 8434 phone sets in order to obtain dual functionality is OK with everyone. Thus, unless I hear otherwise, I will assume this is a closed item. Response: The approach is to have two station lines to each position. One is the station line to the CaIlMaster VI for telephony integration to Power 911. The other is a station line to the 8434 set. Each station line is configured within the G3 for the phone type it is connected to. Under normal conditions, all call activity will occur on-screen via the Power 911 / CaIlMaster VI station. A position's 8434 station would only be used as a backup to workstation failure. POSITRON Page 3 of 5 City of Miami Police and Fire — Addendum to Scope of Work � LSOUTH February 6, 2004 City of Miami E9-1-1 November 12, 2003 Conference Call Notes Attendees included representatives from Avaya (Expanets), Positron and BellSouth discussing issues and possible scenarios regarding the upgrade of the City of Miami's E9-1-1 equipment. The following notes were taken during the call: 1) Issue: Fire Department, having 7 of the 22 positions, does not want the ACD functionality that the Police Department is requesting. They want their 7 E9-1-1 trunks plus their administration lines to appear at all of their positions. Result: The design will support this request on the CaIlMaster VI equipped with the CTI and on the 8434D digital display sets. 2) Issue: Fire Department wants all their lines to appear in both the CaIlMaster VI and their existing 8434D phone sets. This will provide Fire with the functionality of the Positron CTI screen AND will be backed up with the hardwired solution via the 8434D sets. Result: Bridging of the lines on the 7 Fire Positions is supported and included in the design. 3) Description of BellSouth SMARTPath fiber feeder facilities from dual Central Offices: ♦ Eleven E9-1-1 trunks will originate at the Biscayne Tandem and will feed the PSAP via the Grande C.O. ♦ Eleven E9-1-1 trunks will feed the PSAP via the Metro C.O. ♦ A PRI, carrying the administration lines, will feed the PSAP from the Grande C.O. At the PSAP, the fiber will terminate in the two existing DDM -2000 multiplexers (Grande and Metro). The optical signals will be converted into electrical DS1s (one from each multiplexer) and will be fed into two new LineReach channel banks who will, in turn, derive 11 DSOs from each DS1 and feed them into the Positron's Life Line 100 Controller. From there, the 22 E9-1-1 trunks will be fed into the existing Avaya Definity G3 PBX, which will send the trunks to the 22 positions. The third DS1 signal from the Grande multiplexer (PRI) will feed a BellSouth SmartJack (BellSouth demarcation point). Beyond the SmartJack, the PRI will feed into a customer -provided CSU and then into the Avaya PBX. 4) Issue: If the Positron Life Line 100 fails completely, how does the ANUALI information reach the 22 positions? Result: The failure of the Life Line 100 will trigger a signal back to the Biscayne Tandem causing an automatic overflow situation. Currently the PSAP E9-1-1 trunks are set up to overflow into the administration lines. Since the administration lines are fed by means of PRI Service, ANI information will be displayed (this will not occur from calls having a Privacy feature invoked). BellSouth will Page 4 of 5 G� POSITRON City of Miami Police and Fire — Addendum to Scope of Work BELLSOUTH February 6, 2004 further test this next week during the Broward County E9-1-1 equipment upgrade implementation. It must be noted that the Life Line 100 Controller has built-in redundancy in all its common cards (power, communication, etc.). Each Life Line shelf can handle 8 E9-1-1 trunks. If a trunk card fails, only a single trunk will be affected. If the entire shelf fails, a maximum of 8 trunks will be affected, 5) The Avaya Definity G3 PBX uses 8 -port trunk circuit packs. It is recommended that the 22 "911" lines be spread out over 5-6 cards. In case a card failure, only the trunks terminating on that card will be affected (4 or 5). Issue: What happens if the Avaya switch fails completely? Result: The entire PSAP will be affected; however, the PBX failure will trigger a signal back to our Tandem and the automatic back-up (previously described) will come into play. This time, since the administration lines will also be affected, the PSAP will still be down. Manual intervention will be required at the Tandem to implement a different back-up plan to re-route the E9-1-1 calls to either the Fire College or Miami -Dade PSAP (depending on the customer's preference). 6) Issue: Call taker position computer fails. Result: Even though all computer functionality at the particular position is lost, the voice line will not be affected. The recommended procedure is to Park any call currently in progress, and continue handling (with full ANI/ALI and all features) from another position. Please refer to "Backup Mechanism in case of Workstation Failure" on Page 20 of the Scope of Work for details. 7) Issue: If the E9-1-1 trunks from the Life Line 100 to the Avaya PBX fail, does Avaya have the functionality to recognize the failure, test remotely and be able to isolate the problem? Result: Yes, as explained below. BellSouth has the capability to "look" and trace the line from the Tandem to the Life Line remotely and determine if the trouble is in our line/equipment. The Avaya Definity has built-in diagnostics that are running continuously and that monitor the software, the processor parts and the circuit packs. Upon detecting an error condition, the system attempts to fix or circumvent the problem automatically. If unable to do so, an alarm is created and classified as Major, Minor, or Warning. Once a Major or Minor alarm is created, the Definity can notify the user via an LED lamp on a console or a telephone, but will immediately call the Avaya INADS center. Upon call receipt at the center, the EXPERT system analysis will perform additional diagnostics, attempt to further clear the issue, and if unsuccessful transfer the problem to a Repair Technician who will communicate with the client and dispatch a Field Service Technician with a replacement part. Thus, since all troubles occurring between these two pieces of equipment can be isolated, the usual "finger - pointing" will be eliminated. POSITRON Page 5 of 5 NMI
