DIU 2130 and DIU 1130 loopbacks
The DIU 2130 and DIU 1130 loopbacks are shown in the following
figure:
The selected data equipment transmitter output is connected to the
receiver through the associated interface driver and receiver in the DIU.
This looping path allows you to check the operation of the data
equipment and associated cabling to the DIU.
At the same time, the data port of the DIU is also looped back to the DS1
network and returned to the far-end EQPT. This path allows you to
perform end-to-end data port tests and to check the data circuit end-to-
end.
