802.11b International standard for wireless networking that operates in the 2.4 GHz frequency range (2.4 GHz to 2.4835 GHz) and provides a throughput of up to 11 Mb. 802.11g is similar to 802.11b, but this standard provides a throughput of up to 54 Mbps

CAT5 (Category 5 Ethernet cable) - A widely used EIA/TIA Ethernet cable standard. CAT5 cables contain 4 twisted pairs of copper wire and support 100 Mbps Fast Ethernet. CAT5 cable runs are limited to a maximum recommended length of 100m (328 feet). CAT5e and CAT6 cables the stringent specifications for crosstalk and system noise required for Gigabit Ethernet (1000 Mbps) networks.

Client - Any computer connected to a network that requests services (files, print capability) from another member of the network

DHCP - A utility that enables a server to dynamically assign IP addresses from a predefined list and limit their time of use so that they can be reassigned

Ethernet - An IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium

IEM (in-ear monitor) systems are used in broadcast and motion picture production for crew communication, audio monitoring and cueing. May be analog or incorporate voIP.

IFB -Interrupted Feedback (Foldback). Interruptible Feedback (Foldback). A monitoring scheme often used in television broadcasting where the feed of program audio to an on-air person can be interrupted with directions, cues, or other information. Usually integrated into the intercom system

IoIP - (Intercom over IP) Intercom over Internet Protocol topology combines the convenience of intercom PTT and the reach of global network Voice over Internet Protocol (VoIP)

IP - (Internet Protocol) The method by which data is sent from one computer to another using the internet

IP address - The unique set of numbers allocated to your computer to identify it on a network. This number may be fixed/static, or dynamic.

ISP - (Internet Service Provider) a company that enables you to access the internet

Intercom - (Voice Intercoms) 2-way voice communication device with Push to Talk (PTT) operation. Uses include: Security intercoms and internet intercom applications.

IoIP: (Intercom Over Internet Protocol) The use of the Internet Protocol (IP) for transmitting voice communications. VoIP delivers digitized audio in packet form and can be used to transmit over intranets, extranets, and the Internet.

LAN (Local-Area Network) A computer network that spans a relatively small area. Most LANs are confined to a single building or group of buildings. However, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. A system of LANs connected in this way is called a WAN.

MAC (Media Access Control) Address - The unique address that a manufacturer assigns to each networking device.

MPG (MPEG)  Audio compression format used in audio music players and broadband audio streaming systems (ex: Sony™/Apple™/Barix™/Digigram/EtherSound™) 

NAT- Network Address Translation) A router that allows you to keep a set of IP addresses for internal use and another set for external use. This increases security by limiting what IP addresses the outside world has access to and allows the same internal IP addresses to be used on different networks.

Multicast A media (packet) stream that is copied and sent to multiple authorized SUBSCRIBERS (network addresses). Multicast addresses are group addresses. 

PA/IP (Public Address Over IP) System distributed Paging and Audio over TCP/IP networks, bypassing traditional analog switching and wiring runs.

PCM (Pulse Code Modulation) A method by which audio is converted to digital format. Common formats such as CCITT G.711, are used for digitized voice at 64 kbps (8bit x 8khz) bandwidth and may be compressed with formats such as uLaw coding.

PLC (Powerline Carrier Communications) Powerline carrier that uses the existing power cabling found in homes and commercial buildings to connect devices. Speeds range from 60 bps to over 10 Mbps.

Port. The virtual connection point through which a computer uses a specific application on a server.

RJ-11 Six-conductor modular jack used with four-wire cabling. Most common phone jack in the world and is used commonly on phones, modems, and fax machines.

RJ-45 Eight-pin connector used to attach data transmission devices to standard telephone wiring. Commonly used in 10Base-T connections.

Router - A networking device that connects multiple networks together, such as a local network and the Internet.

Server - A network device that provides its resources to other devices on a network

Skype a protocol for  encrypted pc-pc voice communication. Skype is based on  P2P technology incorporated  by  iTalk2u and other systems.

Switch - 1. Device that is the central point of connection for computers and other devices in a network, so data can be shared at full transmission speeds.

VoIP: (Voice Over Internet Protocol) The use of the Internet Protocol (IP) for transmitting voice communications. VoIP delivers digitized audio in packet form and can be used to transmit over intranets, extranets, and the Internet. Applications in Voice Over IP intercoms and (voIP intercom) technology may include TCP IP Paging.

UDP (User Datagram Protocol)  A network protocol for transmitting data that does not require acknowledgement from the recipient of the data that is sent. UDP can carry IP and VoIP signaling.

WAN (Wide-Area Network) Private network facilities, usually offered by public telephone companies but increasingly available from alternative access providers (sometimes called CAPs), that link business networks.

Campus Security Overview, ALERTS and EMERGENCY planning in schools.

IP audio offers increased safety and adds support for students and staff through instantaneous, precise two-way communication. Campus emergency notifications to campus security should be always reachable.

Consider products that  are 100% Voice Over IP network-capable intercoms and paging products and systems. Push-to-Talk technology supplements video systems and add scalable expansion for schools, campuses, educational facilities and universities audio intercoms. These products may be deployed throughout single campuses, among various campuses, across cities and continents and all over the world.

• Use for Campus Alert and campus alert systems
• Provide emergency notification for education and commercial safety to handle emergency action systems and provide two-way dialogue instantly
• Help improve college Emergency Alerts and College safety
• Improve IT support to students, professors and staff in daily use

Products for schools, universities and business campuses also offer some distinct advantages:  Improved capabilities over Mass Text Messaging, including 2-way audio, paging and remote listen-in monitoring.  Audio intercoms used for educational notification systems can be used with Emergency Text Alerts and other emergency notification for schools. Integrated Priority Alert Software for school intercom systems improve security Technology On Campus.

Emergency notification for schools improve student and staff safety and security; enhancing college life, student/staff protection and overall communications.
