ABSTRACT: GR-1436 replaces TR-NWT-001436, Issue 1, but contains NO TECHNICAL CHANGES from that original document. It has been issued strictly to conform with the new Telcordia Technologies document format and GR process, and carries a new issue number and date.

This GR provides the view of Telcordia on generic requirements for the Visual Screening List Editing (VSLE) CLASS feature, which allows a customer to build, maintain, and review a list of Directory Numbers (DNs) via a Server Display Control session using the Analog Display Services Interface (ADSI). This list may then be used by other CLASS features, such as Selective Call Forwarding (SCF), Selective Call Rejection (SCR), Selective Call Acceptance (SCA), or Distinctive Ringing/Call Waiting (DRCW) to provide special terminating treatment to calls received from any of the DNs on the list. In addition, VSLE allows a customer to perform certain administrative functions associated with a supported feature such as feature activation/deactivation, terminating treatment selection, or specification of a remote DN (i.e., a number to which calls should be forwarded). VSLE provides the same functionality as the Screening List Editing (SLE) CLASS feature, but it is enhanced in its use of the ADSI to provide a display-based interface to the customer.
