Local and Remote Tracing
The phone is able to write internal trace files, and to send the trace data to a remote syslog
server. The tracing can be configured in a differentiated way by setting discrete trace levels
for each service.
Please note that it is not recommended to enable all traces to the deepest level. The gener-
ated trace file will exhaust the phone’s memory shortly, and the overall functionality will
slow down.
OpenStage phones generate QoS reports using a HiPath specific format, QDC (QoS Data Col-
lection).
The reports created for the last 6 sessions, i. e. conversations, can be viewed on the WBM or
are reported to the QCU (QoS data Collection Unit).
SEN provides a server application to collect the data. The collected data is sent via SNMP. If
an SNMP server is available, the QDC MIBS can be downloaded from our software supply
server (SWS).
Meanwhile, third party solutions are available which can also deal with the OpenStage QDC
data.
Sometimes everything goes wrong: tracing is of no help, issues are sporadic and the cus-
tomer’s problem cannot be understood. It seems that the last resort is a visit to the customer
to get the needed information.
In such situations, the HUSIM phone simulator can produce relief. It enables the service staff
to access a defined group of phones remotely. The tool works similar to well known remote
control tools for PCs like VNC.
For each phone, a PC application window shows the current status. Every OpenStage phone
model is represented with its complete key layout and display content. The remote visitor
can see all user interactions on the phone. Moreover, he can access the phone keys actively
and in this way operate the phone by remote control. Please note that, for privacy protec-
tion, the user is always informed about the remote interaction.
To get the phone tester up and running, a special dongle key must be uploaded to the
phone. The dongle key and the HUSIM software can be downloaded without additional
charge from SWS/SEBA. The key can be distributed to the phone using the SEN DLS (Deploy-
ment Service) or the phone’s WPI (WorkPoint Interface).
