Memorandum To: Cabarrus County Board of Commissioners From: Todd Shanley, ITS Support Manager Date: 12/31 /2009 Re: 911 Backup Plan This is a request to submit a backup plan to the North Carolina 911 board for the funding of secondary PSAPs as backups to the Cabarrus County 911 center. The Cabarrus County 911 center is currently provisioned with equipment with 10 positions at the primary site and 2 positions at the remote DSS facility. This project will add a total of 11 positions that will have the ability to provide a backup to the Cabarrus County 911 center. Enhanced 911 was incorporated in Cabarrus County in the early 1990s. There are three 911 centers Cabarrus, Concord, and Kannapolis. All three centers receive 911 calls for service; these calls are based on ESN districts. In the past the three centers were standardized on common equipment from CTC. In approximately 1997, the three 911 centers were upgraded to the CML Rescue Star 911 phone system. In this case the three centers had there own servers but standardized on common equipment. This equipment is leased through CTC which is paid for out of 911 fiznds. During the construction of the new Sheriff Administration building the 911 center selected a new 911 phone equipment vendor. The selection of the Positron 911 system enabled the Cabarrus 911 center to utilize the existing IP network. The implementation for the Cabarrus 911 center was completed in three phases. Phase one provided a full Positron Viper for Cabarrus 911 at the primary site. The second phase brought up a second full Positron Viper at the remote site at DSS. The third phase was to link the two Vipers together to provide failover. The third phase provides the Cabarrus 911 system a redundant backend server platform from which to operate. There are three additional phases that will give the citizens of Cabarrus County the knowledge that someone will be there to answer their 911 call. Phase four would supply new 911 phone positions for the Concord PSAP. Phase five would supply new 911 phone positions to the Kannapolis PSAP. Finally, phase six will implement the Intrado network for the three PSAPs. Phases four and five of this project is important to both Cabarrus County, City of Concord and the City of Kannapolis. The CML equipment which the county is leasing from Windstream that runs the Kannapolis and Concord PSAPs has reached its end of life. However, this proposal does not require the replacement of the CML servers only the positions and network switches. We plan to leverage the existing infrastructure of Phase 3 and the fiber connections that currently exist between Concord and the county. We are working with Time Warner to add the City of Kannapolis to the fiber ring that is already in place. When this phase is complete the county will terminate the lease of the CML equipment and Windstream will remove it. This will add 11 additional positions that will have the ability to take calls from the Cabarrus 911 Vipers. These additional positions will have the ability to take calls from the Cabarrus 911 center if and when they are needed. F-6 Attachment number 1 Page 152
