The loop-back test function is the assistant function for the user to adjust equipment
and test the link. The client could set the type of loop-back according to different
needs to realize different test functions.

(1) Local V.35 interface loop-back test ALOOP

V.35

E1Channel

As shown in the above figure, user can set the fractional/transparent mode, related clock
mode and bandwidth of the local converter. If the local V.35 loop-back is successful,
LOOP indicator is ON. When the Router connecting to the local equipment is checking the
interface, the loop-back status could be shown. The local V.35 interface loop-back test is
usually used to test whether the connection of V.35 cable is all right, whether the Router
interface has started working, and whether the clock and data phase relation between
Converter and Router is right or not and so on.

As shown in the above figure, user can set the fractional/transparent mode, related
clock mode and bandwidth of the local converter. If the local E1 line loop-back is
successful, the LOOP indicator is ON. When the Router at the remote site is
checking the interface; the loop-back status could be shown. The loop-back test at
the local E1 line is usually used to check whether the V.35 cable at the remote site
is connected correctly or not, the Router interface at the remote site has started
working or not, and the clock and data phase relation between the Converter and
Router at the remote site is right or not and so no.

(3) E1 line loop-back at the remote site RLOOP

To realize the E1 line loop-back at the remote site, the following pre-conditions must
be guaranteed:
1) This equipment is used point to point in pairs.
