For instance, a system administrator willing to install a later version of a computer program that is being used can schedule that installation to occur when that program is not running. An operating system may automatically install a device driver for a device that the user connects. (See plug and play.) Malware may also be installed ...
ATM Adaptation Layer 5 (AAL5) is an ATM adaptation layer used to send variable-length packets up to 65,535 octets in size across an Asynchronous Transfer Mode (ATM) network. Unlike most network frames, which place control information in the header , AAL5 places control information in an 8-octet trailer at the end of the packet.
ATMs are known by a variety of other names, including automatic teller machines (ATMs) in the United States [1] [2] [3] (sometimes redundantly as "ATM machine"). In Canada, the term automated banking machine (ABM) is also used, [ 4 ] [ 5 ] although ATM is also very commonly used in Canada, with many Canadian organizations using ATM rather than ABM.
AAL Type 5 is similar to AAL 3/4 with a simplified information header scheme. This AAL assumes that the data is sequential from the end user and uses the Payload Type Indicator (PTI) bit to indicate the last cell in a transmission. Examples of services that use AAL 5 are classic IP over ATM, Ethernet Over ATM, SMDS, and LAN Emulation (LANE).
Multiprotocol Encapsulation over ATM is specified in RFC 2684. It defines two mechanisms for identifying the protocol carried in ATM Adaptation Layer 5 (AAL5) frames. It replaces RFC 1483, a standard data link access protocol supported by DSL modems .

PAX Technology S90 credit card terminal with a Visa card inserted.. A payment terminal, also known as a point of sale (POS) terminal, credit card machine, card reader, PIN pad, EFTPOS terminal (or by the older term as PDQ terminal which stands for "Process Data Quickly" [1]), is a device which interfaces with payment cards to make electronic funds transfers.
ATM Adaptation Layer 2 (AAL2) is an Asynchronous Transfer Mode (ATM) adaptation layer, used primarily in telecommunications; for example, it is used for the Iu interfaces in the Universal Mobile Telecommunications System, and is also used for transporting digital voice. The standard specifications related to AAL2 are ITU standards I.363.2 and ...
