Control Unit Problems
Corrective Action
This result indicates that facility is correctly administered and
established on Layers 1, 2, and 3. However, a problem
associated with the provisioning at the CO for data calls was
detected. If the facility is intended to provide data calls,
perform the following tests (described later in this section)
with either digital data terminals or analog data terminals and
modem pools. Record the results before contacting the LEC:
Outgoing Data Call Test
Incoming Data Call Test
If data terminals are not available, contact the LEC and advise
them that the provisioning for data on the facility requires
checking. If more information is required, contact the NSAC
and provide them with the result code, the slot number, the
port number and the site information (remote access number,
etc.)
Possible causes for this error are:
No calling party number
(Error identified at Incoming Data Call Test, Step 3)
Note: One or both of the following conditions can result in Note:
the absence of calling party number:
- Originator is provisioned for privacy.
- Receiver (BRI line under test) is provisioned for non-
delivery of calling party information.
Outgoing and/or incoming calls are not possible at all
times .
(Error identified at Outgoing Data Call Test, Step 2 and/or
Incoming Data Call Test, Step 2)
This condition may or may not be detectable by
performing the above tests only once. Therefore, repeat
the tests several times, mixing outgoing and incoming
data calls, varying the disconnecting end, connecting on
some calls but not others, etc.
X.25 provisioned for either B- or D-channel
This condition is not detectable by manual testing.
