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.
NOTE:
The 800 NI-BRI module must be restored (removed from the Maintenance
Busy state) before performing this test.
Assign the BRI line to a data terminal.

If using a facility on the system as a destination, assign the destination
facility to another data terminal.
Place a test call to the BRI line under test.

Verify that alerting is indicated at the data station associated with the BRI
line. If not, check that the dialed number corresponds to the DN of the line.
If the data station associated with the BRI line under test can

display calling party number, verify that the originating DN appears
on its display.
If not, record that the calling party information displayed at the
destination telephone is either incorrect or absent.
Answer the call and verify the connection.

The data station may be programmed for auto-answer. Verify that the
green LED flashes until the call is answered.
Disconnect the call from either the originating or receiving end.

If the number is not correct, redial the call.
Otherwise, record that the incoming data call test has failed and
note the type of tone (busy, reorder, ringback, etc.) heard at the
originating end.
