Issue 2 April 1996

1. Check to see whether the connection between the Proxy Agent and

the PBX is up, and that the Proxy Agent is running and
communicating with the NMS.

2. Make sure that the PBX is in the Proxy Agent’s clients screen.

3. Try the refresh again.

There is already a Circuit Pack refresh in progress. If you still want to
request another refresh, please wait until the current one is complete.

Action: Wait for the current refresh to complete before requesting another
one.

There is currently a data request in progress, please try the Bulletin Board
Refresh again later.

Action: Wait for the current refresh to complete before requesting another
one.

There is currently a data request in progress. Please try the Configuration
Data Refresh again later.

Action: Wait for the data request to complete before requesting the
refresh.

There is already a Circuit Pack refresh in progress. Please don’t press any
cabinet buttons until it is done.

Action: Wait for the circuit pack refresh to get to the point where it is
receiving the circuit pack data before clicking on a cabinet icon.

WARNING: The Circuit Pack refresh has failed. The data displayed is based
on the data cached on the Proxy Agent. This data may be out of sync with
the actual switch data.

The most likely cause of this problem is the connection between the Proxy
Agent and the DEFINITY G3 PBX being down or turned off.

Action: Try the following procedure.

1. Check to see whether the connection between the Proxy Agent and

the PBX is up, and that the Proxy Agent is running and
communicating with the NMS.

2. Make sure that the PBX is in the Proxy Agent’s clients screen.

3. Try the refresh again.

WARNING: The Bulletin Board refresh has failed. The data displayed is
based on the data cached on the Proxy Agent. This data may be out of sync
with the actual switch data.

The most likely cause of this problem is the connection between the Proxy
Agent and the DEFINITY G3 PBX being down or turned off.
