4.5 Remote Loop Back
This test is activated by depressing the "Remote Loopbk"
push button. The test checks the performance both of the local
and the remote EOe-1 units, as well as their interconnecting
lines. The remote digital loop back test consists of providing a
loop back at the remote
EOe-1
(see Figure 4.3).
A system test may be performed by first depressing the
remote loop back switch, then depressing the pattern switch. The
test pattern will be generated, sent out the E1 link and looped
back by the remote unit. If no errors are indicated by the error
LED, the link test has been successful.
