3.2
Test loopbacks are specified by the national PTTs in order to facilitate the location of
defect systems. Four different loopbacks are defined. The position of each loopback is
illustrated in
•
Figure 24
Loopbacks #1, #1A and #2 are controlled by the exchange. Loopback #3 is controlled
locally on the remote side. All four loopback types are transparent. This means all bits
that are looped back will also be passed onwards in the normal manner. Only the data
looped back internally is processed; signals on the receive pins are ignored. The
propagation delay of actually looped B and D channels data must be identical in all
loopbacks.
