2.2 POPULATING OSSCN SCREEN IN WFA/C

The OSSCN screen will have different fields populated depending on the span type and line coding .

The OSSCN screen may be populated by both:

•

SSIM technician - SSIM technician will use Craft Access Remote Testing (CART)

•

SSTC technician - SSTC technician will use WFA/C to populate OSSCN screen.

The following fields must be populated for proper documentation during the circuit provisioning process. The

only 'required' fields that must be populated by the Special Services Test Center Technician are "ES" and

“Accepted By”. All other fields could by populated by the I & M technician through CART. The SSTC tester has

final responsibility upon circuit completion to verify information is populated on the OSSCN screen. The SSIM

technician must populate all fields except “ES” and “Accepted By” when CART is used to post CTR1

complete.

•

ES - Populate (A-Z), (Z-A), LPBK depending on type of test.

•

Installer - name of installer(s) at A and Z locations.
