Cable Type
Application Scenario
Description
Adapter cable plus straight-
through cable
Telecommunications
terminal
An adapter cable has an RJ45
plug at one end and an RJ45
socket at the other end. The
cable converts the wire
sequence on a dumb terminal
to the standard wire sequence
for telecommunications
devices.
The RJ45 socket of the
adapter cable is connected to a
straight-through cable, which
is connected to a terminal.
Adapter cable plus
asynchronous serial cable
Common network
device
An asynchronous serial cable
has an RJ45 connector at one
end and a DB25/DB9
connector at the other end.
Serial port server
The wire sequences of twisted
pairs in the two RJ45
connectors are determined by
the type of signals transmitted
from the connected terminal.
