After you dial the ANAC number and get a response,
the phone number of the line pair that the test set is
connected to is shown on the display. If the ANAC
response is greater than 10 digits, the last 10 will be
displayed. The test set is automatically muted in visual
ANAC mode. If a visual response is not available, an
audible response is given.
You can also enter the ANAC number in speed dial
location 9 and the test set automatically enters Visual
ANAC mode when the speed dial is used. If a visual
response is not available, an audible response is given.
Use one of the other speed dial locations (0-8) if you
always want an audible response.
ANAC mode is turned off when you switch to Monitor
mode. If ANAC mode is off, the ANAC voice response is
audible on the handset or speaker.
