.
topology
Logical and/or physical arrangement of stations on a network.
transceiver modules
Transceiver modules come in longwave, extra longwave, or
shortwave laser versions, providing a single fiber connection.
transfer rate
The speed with which data can be transmitted from one device to
another. Data rates are often measures in megabits (Mbps) or
megabytes (MBps) per second, or gigabits (Gbps) or gigabytes per
second (GBps).
transistor-transistor
logic
TTL. A common type of digital circuit in which the output is derived
from two transistors. The term TTL is often used to describe any
system based on digital circuitry.
transmission control
protocol
TCP. The transport layer for the transmission control
protocol/Internet protocol (TCP/IP) protocol widely used on
Ethernet networks and any network that conforms to U.S.
Department of Defense standards for network protocol. TCP
provides reliable communication and control through full-duplex
connections

trap
Unsolicited notification of an event originating from a simple
network management protocol (SNMP) managed device and directed
to an SNMP network management station.
trap host
Simple network management protocol (SNMP) management
workstation that is configured to receive traps.
trap recipient
In simple network management protocol (SNMP), a network
management station that receives messages through SNMP for
specific events that occur on the arbitrated loop device.
trunk cable
Cable consisting of multiple fiber pairs that do not directly attach to
an active device. This cable usually exists between distribution panels
and can be located within, or external to, a building
