100BASE-TX

100-Mbps baseband Fast Ethernet specification based on the IEEE 802.3 standard. 100BaseTX uses two pairs of either UTP (Unshielded Twisted Pair) or STP (Single Twisted Pair) wiring. One pair is used to receive data; the other is used to transmit data.

10BASE-T

10-Mbps baseband Ethernet specification based on the IEEE 802.3 standard. 10BaseT uses two pairs of UTP (Unshielded Twisted Pair) wiring. One pair is used to receive data; the other is used to transmit data.

AAL

ATM Adaptation Layer. The AAL is a collection of standardized protocols that adapt different classes of applications to the ATM layer. This is necessary for ATM to support various types of services with different traffic characteristics and system requirements. The AAL is divided into the Convergence Sublayer (CS) and the Segmentation and Reassembly Sublayer (SAR).

AAL5

One of several types of AAL. AAL5 is used for LAN Emulation (LANE).

ABR

Available Bit Rate. An ATM service in which the network guarantees a minimum data transfer rate and allows data to be transferred at a higher rate when the network is free.

Address Resolution

Conversion of an IP address into a corresponding physical address. This is usually done using ARP (Address Resolution Protocol).

Agent (Network Agent)

A special control module that interfaces between the network manager and the managed devices, using the MIB as a management terms dictionary. Network Agents relay device events and execute instructions via embedded software.

Alarm

An audible or visible warning signal alerting designated management stations that
