TA
Terminal Adaptor. Used within ISDN to
convert between non ISDN and ISDN
references.
TE
Terminal Equipment.
TEI
Terminal Endpoint Identifier - an
address on a multidrop ISDN that
identifies a particular device. May be
either permanently assigned or
assigned on demand. E.g. TEI=127 is a
broadcast, TEI=0-63 are permanently
assigned, TEI=64-126 are dynamically
assigned.
Teletex
A data transmission standard, typically
operating at 1200bits, which is an
upgrade on the slower telex standard.
Terminator
A resistor connected across the ends of
a transmission line to satisfy the need
for a constant impedance to reduce
reflection and distortion of signals
travelling down the transmission line.
Transmission lines are normally
terminated in a pure resistor
whose Ohmic value is the same as the
characteristic impedance of the
transmission line.
TNV
Telecommunication Network Voltage
circuit. Test circuit for definition of
safety in telecommunication systems.
