Figure 98: Internal Looparound Test
A signaling message is sent through the digital port circuit pack to the data module, requesting it
to enter looparound mode. A test pattern is then sent from the TN771D Maintenance/Test circuit
pack, over the path illustrated above, and back to the TN771D where it is checked for
consistency.
The test aborts if any of the following local resources are not available:
● A digital port on the TN771D. There are two such digital ports, but only one may be
used at a time.
● Two TDM time slots
● An idle digital port connected to the data module
