how access magento ProductConfigure.spConfig

I'm trying to load extra information for new orders thru javascript on admin area. I need to get the spConfig info from other script. but, I can't find how can access it. the file I'm using to load it is the /adminhtml/default/default/template/catalog/product/composite/fieldset/configurable.phtml

<script type="text/javascript">
    var config = <?php echo $this->getJsonConfig() ?>;
    if (window.productConfigure) {
        config.containerId = window.productConfigure.blockFormFields.id;
        if (window.productConfigure.restorePhase) {
            config.inputsInitialized = true;
        }
    }
    ProductConfigure.spConfig = new Product.Config(config);
</script>

any help would be great! thanx!
