7.4.10 Call Tracing
Warning:
Call tracing is an intrusive process. Its use may SERIOUSLY compromise the
performance of the product. It should only be used by, or under supervision of
Westell engineers.
The Call Tracing product takes Layer 3 data and passes it through the capture filter (as
defined by the user) and stores the result in a buffer on the shelf. The user may then specify
a retrieval filter which returns the chosen data from the buffer and displays it to the screen
and in a file.
Capture Filter
Allows the user to choose the lines and channels on which to capture data. Check the clear
shelf buffer to clear the buffer of any previously captured data.
Retrieval Filter
Allows the user to choose the lines and channels on which to retrieve any previously
captured data. It is also possible to retrieve messages according to time constraints, called
party numbers, the call type (e.g. data calls only), the call state, (e.g. calls in progress only),
or the stack type (e.g. originating stack only). It is not possible to set or reset the capture
filter whilst retrieving data.
Call Trace Log
The Call Trace Log contains a text area in which the user may view data being currently
retrieved, load a saved log, save/print the current log and stop the data retrieval, scroll
through the current records using the scroll bar, and get the next/ previous set of records
using the up/down arrow icons.
