800 NI-BRI Module Problems
If using a facility on the system as a destination, assign the destination
facility to another data terminal.
Dial the destination number. (In a Centrex environment, it is
necessary to dial a 9 before the destination number.)
Verify the following results and note any failures:
You may hear dial tone at the beginning of dialing and ringback
after completion. Alerting may be indicated at the destination.
If both ringback and alerting are absent, check that the dialed
digits are those of the destination DN. Redial, if necessary. If the
call could not be established and the dialing was correct, record
that an outgoing data call cannot be completed from this line and
indicate the type of tone, if any, that was present at both ends.
If the destination telephone can display the calling party number,
verify that the DN of the BRI line under test is displayed correctly.
If not, record that the calling party information displayed at the
destination telephone is incorrect or absent.
Answer the call at the destination telephone and verify the
connection.
The destination data extension may be programmed for auto-answer.
Verify that the red and green LEDs next to this button are on steady and
the communication path is established.
Disconnect the call from either the originating or receiving end.
Verify that the green LED turns off and the communication path is
removed.
Incoming Data Call Test
Place a data call from a known working facility to the BRI line under test. See
the Data and Video Reference for details regarding answering a data call with
specific equipment.
