CSG Systems International (CSGS)

CSG TechNet Web. CSG TechNet Web integrates with CSG Workforce Management to allow field technicians to receive and manage work orders without dispatcher assistance via any browser-based device that can support Internet Explorer 5.5 (or higher).

ACSR module for HSD. The ACSR module of HSD allows customers, through the graphical user interface, to access subscriber information on CCS as it relates to customers’ offering of high speed data services.

CSG SmartLink^TM Micro-Level. CSG SmartLink™ Micro-Level is an XML interface that provides a mechanism for customers to use the open standards of the extensible Markup Language (XML) to communicate with CSG’s core CCS system. The XML technology allows a customer to build applications using these open standards. Message based XML is used for communicating upstream to core CSG systems. The data communications method for the CSG SmartLink^TM interface is TCP/IP. Customers can use either CSG’s External Integration Protocol (EIP) or HTTP to organize, request and reply records on the TCP/IP data stream. CSG provides the customer with the CSG SmartLink^TM Micro-Level Interface Specification and the XML document type definitions (DTDs) for each defined XML activity. XML requests sent by the customer must use the DTDs as supplied by CSG and validate successfully against those DTDs.

CSG SmartLink^TM BOS. CSG SmartLink^TM BOS is a macro-level XML interface that utilizes business logic technology to combine the existing CSG SmartLink^TM (micro-level) activities into Business Functions. The XML technology allows a customer to build applications using these open standards. Message based XML is used for communicating upstream to core CSG systems. The data communications method for the CSG SmartLink™ BOS interface is TCP/IP. Customers can use either CSG’s External Integration Protocol (EIP) or HTTP to organize request and reply records on the TCP/IP data stream. CSG provides the customer with the CSG SmartLink^TM BOS developer’s guide and the XML schemas for the specific functionality purchased. XML requests sent by the customer must use the schemas as supplied by CSG and validate successfully against those schemas. Customer will have access to current and subsequent releases as such releases are made available by CSG.
