Call Simulator Facility
The call simulator facilities of the Avaya Media Processing Server (MPS) Series
system allow testing of various system and application functions. Primarily, this is
done to test load capacity and performance under various conditions before having the
system process actual phone calls. Script commands mimic actions that a caller
typically performs from the viewpoint of a caller dialing into the system.
Simulation scripts are loaded and parsed into TMS memory. Once loaded, they are
assigned to one or more resource sets (rsets), after which they can be executed.
Under normal conditions, scripts execute as written: however, should a resource set
the script is bound to be destroyed, or a resource required for simulation not be
available in the set, the flow of execution is disrupted. In these cases, an asynchronous
event containing the event that occurred, the resource set involved, and the script that
generated the cause is returned to the command shell from which the simulation was
initiated. For additional information on actions discussed in this paragraph, see
“Command Line Interface” on page 200. For more information on resource sets and
their mappings, see The tms.cfg File on page 106.
Scripts are written in ASCII format using the scripting language and constructs as
described in “VEMUL Script Format” on page 195.
For best performance results, the system should be in an offline state when the call
simulator commands are issued. To avoid any potential consequences, it is
recommended that the systems phone lines be physically disconnected before
activating any simulator functions.
VEMUL Script Format
The VEMUL script language provides basic programming constructs that are used to
generate complex script scenarios such as looping and "if-then-else" statements (see
“Script Commands” on page 196). These ASCII script files can contain multiple
START-END Statement blocks. This block defines the actions that a script is to
execute, and is formatted in the following construct:
start
<script commands>
end
Note that * is not a valid character when using call simulator.
If more than one START-END Statement block exists in a script, they are executed
consecutively up to and including the last one. After the final START-END Statement
block has been completed the script stops running. To execute the script again it must
be restarted by using the scriptcntrl command (see “Command Line Interface”
on page 200). Alternatively, particular commands within the script can be reiterated
by using the REPEAT Statement (see “Script Commands” on page 196).
