This SR, a companion document with TR-NWT-001273, Generic Requirements for an SPCS to Customer Premises Equipment Data Interface for Analog Display Service, describes the compatibility guidelines for Customer Premises Equipment (CPE) to operate with the Analog Display Services Interface (ADSI) protocol. These CPE guidelines allow ADSI CPE to interact with ADSI switches/servers, thus providing users with screen-based user interfaces. CPE that comply with these guidelines are expected to function on multiple vendor switches/servers. This Bulletin clarifications to the Analog Display Services Interfaces (ADSI), to its Protocol and to its CPE compatibility guidelines as a result of issues that arose from work to produce laboratory prototypes and from field trial experience.
