Network Tests
Network tests control the activation of loopbacks and the
initiation of data test patterns.
Network tests are run on the Network Interface (NI). You
can select three different test configurations to determine
the type of loopback and the pattern to run. Test results
display in the LCD window.
Loopback Tests
A number of different loopbacks can be invoked locally
from the front panel, by T-Watch PRO commands, or re-
motely by using special in-band codes (AT&T D4 net-
work loop-up and loop-down codes). Additionally, the
loopbacks can be remotely controlled by means of out-of-
band commands by the T1 ESF FDL or from T-Watch PRO
by a modem connection.
Executing tests will disrupt some of the normal operation. See individual menu
items concerning tests before executing.
Executing Network Tests will disrupt normal data flow unless only TST DS0s
are selected for testing.
