Piedmont Regional Voice over IP Pilot Program A Public/Private Partnership The Piedmont Regional Voice over IP Pilot is the result of a partnership agreement negotiated between Cisco Systems Inc. and the City of Danville Police Department. Project supported by: NIJ Comm. Tech NLECTC-NE - NLECTC-SE & Sheriff’s Association of Texas 2
Piedmont Regional Voice over IP Pilot Program Partners 3
Piedmont Regional Voice over IP Pilot Program Public Safety participants • • • City of Danville, Virginia - VHF Radio System(s) Pittsylvania County, Virginia - VHF Radio System Caswell County, North Carolina - UHF Radio System North Carolina State Highway Patrol - Conventional VHF & Trunked 800 MHz Radio Systems And Virginia State Police - Regional VHF Radio channel & Virginia Statewide channel. Corporate Participants • Cisco Systems Inc. – Equipment and technology. • Sprint Corporation – MPLS internetworking links. 4
Piedmont Regional Voice over IP Pilot Program – Comm. Tech’s Role – Assist with formulating Regional Governance. – Document: • Deployment & operational issues • Network design & implementation issues • Understand the underlying infrastructure (the “cloud”). – Act as an honest broker 5
Piedmont Regional Voice over IP Pilot Program – Participation in a long term multi-phase regional pilot spearheaded by Danville, VA. and Cisco, with regional MPLS links provided by Sprint. – Be an advocate for Danville Police & Adjacent towns/counties including neighbors across the state line. – A Public/Private Partnership - Comm. Tech is not providing funding for software or equipment… just manpower. 6
Comm. Tech Considerations: • Comm. Tech is not going to, nor are we planning to, compare IPICS features with those of other Vo. IP products. – Vendor-specific, or generic issues? – Product differentiators to Public Safety will reside in the product features made possible by the underlying IP technology. – Each vendor product has its own set of features and implementations that make this technology useful. – They are not all the same in content or quality, and are (typically) not interoperable between vendors at an IP level. – In this case it’s the IPICS software suite that defines how the overall product will work for Danville. 7
Piedmont Regional Voice over IP Pilot Program Background • • Lack of a common frequency to connect Virginia and North Carolina agencies During emergency situations, dispatchers relayed information via land lines – Officers drove out of radio system coverage. Technical issues – Inadequate infrastructures – Security & Reliability Administrative issues – Participating agencies lacked existing framework for interoperability – Sharing control of resources 8
Piedmont Regional Voice over IP Pilot Program - Goals • Administrative – Establish multi-agency governance. • Operational – Establish Vo. IP interface with existing land Mobile Radio Networks. – Direct PSAP-PSAP Vo. IP communications. – Frequency Sharing (cross programming) among agencies. – Remote Vo. IP access. • Technical concerns – No direct change to radio infrastructure, or infrastructure security & reliability. – An IP overlay facilitating new communications functionality. 9
Piedmont Region Before After (Goal) RF Interoperability No common Frequency crossprogramming & Vo. IP gateway between systems Officer – PSAP/ Dispatch operability Officers left coverage of home system & contact with dispatch center Remote PSAP access & direct officer access to compatible neighboring systems Technical issues – RF network • Inadequate infrastructures • Security & Reliability • No change to RF infrastructure • No change to Security & Reliability Administrative & Governance issues No mechanism for in place sharing/control of RF resources Multi-Agency Gov. structure in place for sharing/control of Radio/Vo. IP resources 10
Piedmont Regional Voice over IP Pilot Program This project implementation facilitates: • Dispatch Center Interoperability – Direct IP based voice communications (hotlines) between dispatch centers. – Remote Access to neighboring radio resources • Direct End-User Interoperability – – – VHFLB/VHF/UHF & 800 MHz Many currently operate on conventional VHF frequencies. Cross-programming/sharing of channels. Bridging & gateway functions. Familiar geographic bridging limitations, related to coverage, still apply for mobile users. 11
Piedmont Regional Voice over IP Pilot Program This project implementation facilitates (cont…): – Remote communications with home agency dispatch will be facilitated for mobile users moving out of direct range of home system coverage into a compatible system. – Remote access to radio resources from Vo. IP enabled workstations/IP telephones. – The Cisco IPICS application add Cisco specific features & operating environment. 12

Piedmont Regional Voice over IP Pilot Program Phase III Technical Details • North Carolina Highway Patrol – Access router installed • Back-to-back routers with a T-1 (TDM) interface as a fire-break. • Internet VPN will be used for IPICS control • Only voice traffic will be passed through the T-1 fire Break. – Issues with existing JPS ACU-1000 IP network when network link is shared. – Issues with Non-Cisco Router base – Issues with console high-voltage DC interface to base station radio controller 21
Piedmont Regional Voice over IP Pilot Program Phase III Technical Details Virginia State Police – A single router with analog interface to a VHF base station via Orbacom Console. – Old DOS-based dispatch console (software and hardware). – Staffing / expertise (issue “programming”). 22
Piedmont Regional Voice over IP Pilot Program Observations: • • • There is a disconnect in expertise between the IP world and the LMR world. End-to-end network ownership of user talk paths must be established. All stakeholder must be involved in plans – Practitioners as well as dispatchers as well as network maintainers. – Legacy system contract support – also stakeholders With IP technology, problems can be created from a distance. – Not only IP-IP issues, but with non-IP components. Make sure the vendor has a detailed plan 23
