•Remote Console Site at a Distributed Conventional Hub Site in a Conventional Subsystem <br /> Console sites are designated as co-located or remote based on how they interface to the masterSite <br /> (zone core).A console site is considered co-located if the site's Ethernet LAN switch is connected <br /> directly to a port on one of the master site LAN switches.Up to four console sites can be co-located at <br /> a master site that includes two master site LAN switches. <br /> Remote Console Sites require a console site router or Site Gateway device and are connected to the <br /> zone core through a Wide Area Network(WAN)link.Large control rooms with many dispatch <br /> consoles may be divided into two or more console sites to support performance and availability <br /> requirements. <br /> 2.3.2 Dispatch Console Subsystem <br /> A Console Site can contain various Dispatch Console Subsystems each consisting of various different <br /> components depending on the console site architecture and features purchased. Dispatch console <br /> operator positions can share some of the subsystem equipment at a console site.A Dispatch Console <br /> Subsystem could contain any of the following equipment: <br /> • MCC 7500 Dispatch Console Operator Position(a Windows-based platform) <br /> • Voice Processor Module(VPM)for each operator position—Interface to peripheral equipment <br /> • Peripheral Equipment: Speakers,Microphones,other peripherals <br /> • Archiving Interface Server(AIS)—interface support for the console and logging equipment <br /> • Logging Recorders and Replay stations—for audio and information archiving <br /> • Aux I/O Servers—an interface external components with the console <br /> • Ethernet LAN Switch—Remote Console Site <br /> • Site Router or Site Gateway devices(for a Remote Console Site) <br /> Equipment at a remote site that would not be considered part of the dispatch console subsystem but <br /> might be co-located with the dispatch console subsystem could include,but may not be limited to,the <br /> following: <br /> • Network Time Protocol source <br /> • Conventional Channel Interface devices(routers or site gateway devices) <br /> • Conventional Base Radios <br /> • Conventional Site Controller <br /> Each Console Operator Position has a dedicated VPM which interfaces to the Ethernet LAN Switch at <br /> the console site.Additionally,if the Audio Logging is implemented,the Archiving Interface Server <br /> (AIS)also has a dedicated VPM.The VPM provides all the audio processing services and <br /> encryption/decryption services for the VPM-based dispatch console and the AIS which include the <br /> following: <br /> • Vocoding services capable of supporting AMBE and IMBE <br /> • Audio processing services-capable of supporting audio level adjustments, summing,filtering, <br /> and multiple, simultaneous audio streams. <br /> • Encryption and decryption services-Capable of supporting multiple simultaneous <br /> encryption/decryption sessions using multiple algorithms and multiple secure keys. <br /> Orange County,North Carolina <br /> MCC 7500 Console System Use or disclosure of this proposal is subject <br /> to the restrictions on the cover page. <br /> ® Motorola Solutions Confidential Restricted System Description 2-5 <br />
