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
