The eterra OASIS Home Page, shown in Figure 3, is the Web page that provides access to any of the OASIS templates. Normally, this is where you start all your operations. Note that each OASIS template has two ESCA Home Page links on the bottom of the image. Be sure to click the ESCA Home Page link on the right to return to the eterra OASIS Home Page.

Figure 3: ESCA Home Page

The ESCA Home Page contains lists of templates grouped into the five categories mentioned previously: Transmission Services, Ancillary Services, Miscellaneous, Messages, and Provider Maintenance. Before discussing templates in those categories, however, note the Batch Uploads link at the top of the page. If you want to upload a batch, click Batch Uploads. Figure 4 shows the Batch File Upload template where you can enter a file name to upload the batch you want.
