Digi Digi Digi Digit t t tal Lo al Lo al Lo al Loo o o opback pback pback pback Loops the signal while it is in a binary digital state. This test may
affect adjacent voice module timeslots. It faces the backplane of the
shelf, so a far-end site should see this loopback. Digital loopback
may be performed on only one channel at a time.
Anal Anal Anal Analo o o og Loo g Loo g Loo g Loop p p pback back back back Loops the signal while it is in an analog state. Analog loopbacks face
the backplane and are visible at the far-end site. The signal passes
through the digital to analog conversion process and then is
converted back to a digital format again. This loopback tests the
CODEC. Any number of analog loopbacks may be active at one time.
