1.0 Central System 1.1 The system architecture shall be based on an industrial rack mount server - client design where all calls are maintained on a central server. Access from PC/clients shall be over an Ethernet connection. 1.2 The system shall be equipped with a minimum 2TB RAID1 hard drives buffer array to support a minimum of 165,000 channel hours of data for instant recall playback and buffering. 1.3 The system shall include NAS (Network Attached Storage) with a minimum storage capacity of 2TB for archiving. 1.4 The system shall be equipped with dual hot swap redundant power supplies. 1.5 The system shall support Network Attached Storage of calls to a Microsoft based NAS server or Storage unit with an option for SAN support. 1.6 The system should support central archiving from multiple recording systems to one centrally located unit. 1.7 The system shall be equipped with a touch screen front panel display or Monitor, Keyboard, Mouse for ease of media changeout, configuration, status readout, call playback and CD burning. The recorder shall also be equipped with a speaker and manual volume control. 1.8 The preferred operating system is a Linux but a Windows Server operating system is acceptable. However, a home edition Windows OS is not acceptable. 1.9 The system shall have a relational SQL database of all recorded calls. A no license fee relational SQL database is preferred that provides: Relational SQL database of all call records Up to 12 Million calls may be indexed in the call records database Programmable retention period ODBC (database access) driver available 1.10 The system shall keep its time synchronized to a master clock. The acceptable time codes are NTP over Ethernet or NENA Standard Format 0, 1, or 2 over RS-232. 1.11 Other than the record cards, the vendor shall confirm that all system major components are COTS non-proprietary parts. 1.12 The system shall support multiple 10/100/1000MB Base-T interfaces for remote Ethernet access and be equipped with dual bondable NIC cards. 1.13 The system shall capture and store important information to facilitate management. This history & error log information will include alerts, user passwords and profiles, deck status, user access audit trail, media library records etc. 1.14 The system shall provide buffering of all recording on the hard disk and automatically transfer the recording to the archive media. The transfer will be automatic on a programmable basis. 1.15 The system shall also provide backup buffering once the media is full or removed from the archive drive up to the full amount of record storage on the hard disk. This backup buffering will be for all archive drives in the system. The buffered recordings shall be automatically transferred to the archive media when the archive drive or drives are returned to the ready to record mode. 1.16 The system shall provide the ability to playback from one archive drive while others continue to record. 1.17 The system shall provide for orderly shutdown upon complete power outage when equipped with a smart UPS unit. The system shall also automatically restart and return to last operating mode upon power restoration. 1.18 The system shall display the recording space left on record archive media in use. 1.19 The system shall allow remote monitoring & configuration via a web- based application from any Windows workstation through a LAN connection. 1.20 The system shall be able to record the following Next Generation 9-1-1 interfaces. NENA-standard SIP-Invite method for recording of NG9-1-1 primary interactions NENA-standard Next Generation 9-1-1 Logging Service with WSDL-based data logging/retrieval interface and RTSP 2.0 System Networking Capabilities 2.1 The system shall allow for a minimum of 8 simultaneous remote client connections to the central server. The vendor shall discuss the capabilities and maximum limits on connections. 2.2 The system shall allow for a Live Monitor function from each client or Web-based application with a minimum of 16 simultaneous channels selected. 2.3 The Live Monitor function access shall be limited to only authorized channel access based on a user account profile. 2.4 The system shall allow for an Instant Recall function from each client. The Instant Recall function should support a minimum buffer size of 24 hours to support recall of up to a full shift. 2.5 The instant Recall function access shall be limited to only authorized channel access and timeframe based on a user account profile. 2.6 If multiple digital recorders are employed in the installation, the system should provide viewing and retrieval from, all recorders in a unified manner from one user interface. 2.7 The user client software or web-based software shall be able to retrieve calls for playback from a Network Attached Storage server.
