Asynchronous Transfer Mode
See ATM
ATM
Asynchronous Transfer Mode. The international standard for cell relay so that multiple service types (such as voice, video, or data) are conveyed in fixed-length (53-byte) cells. Fixed-length cells allow cell processing to occur in hardware, thereby reducing transit delays. ATM is designed to take advantage of high-speed transmission media, such as E3, SONET, and T3.

CPE
Customer Premises Equipment. Terminating equipment, such as terminals, telephones, and modems, supplied by the telephone company, installed at customer sites, and connected to the telephone company network. Can also refer to any telephone equipment residing on the customer site.
CRS
Carrier Routing System. The Cisco® CRS-1 Carrier Routing System is the industry\\\'s only fully modular and distributed routing system that enables service providers to deliver a suite of data, voice, and video services over a highly available and highly scalable IP Next-Generation Network (NGN) infrustructure.
CSA
Cisco Security Agent. CSA provides threat protection for server and desktop computing systems, also known as endpoints. It helps to reduce operational costs by identifying, preventing, and eliminating known and unknown security threats.
CTI
Computer Telephony Integration. The name given to the merger of traditional telecommunications (PBX) equipment with computers and computer applications.

DDoS
Distributed Denial of Service. During a DDoS attack, multiple hosts send legitimate requests, with malicious intent, for service to a single target. Any resource connected to the Internet can be a target, including DNS servers, e-mail services, online applications, or router interfaces. In the worst case, faced with an onslaught of requests, either the Web server or its upstream router fails and all traffic stops.

ISP
Internet Service Provider. Company that provides Internet access to other companies and individuals.
ISR
Integrated Services Router. Embeds security and voice services into a single routing system for fast, scalable delivery of mission-critical business applications.
IVR
Interactive Voice Response. Term used to describe systems that provide information in the form of recorded messages over telephone lines in response to user input in the form of spoken words or, more commonly, DTMF signaling.
LAN
Local Area Network. High-speed, low-error data network covering a relatively small geographic area (up to a few thousand meters). LANs connect workstations, peripherals, terminals, and other devices in a single building or other geographically limited area. LAN standards specify cabling and signaling at the Physical and Data Link layers of the OSI model. Ethernet, FDDI, and Token Ring are widely used LAN technologies.
LEAP
Light Extensible Authentication Protocol. LEAP, or EAP-Cisco Wireless, is the 802.1X authentication type that is available on Windows CE devices. Support for LEAP is provided in the client adapter\\\'s firmware and the Cisco software that supports it, rather than in the operating system. With LEAP, a username and password are used by the client adapter to perform mutual authentication with the RADIUS server through an access point.
