Summary:	This disclosure updates the Call Event and Management Signaling Service (CEMSS) announcement document issued on August 28th, 2007. An additional Service Parameter Update interface capability is included in this issue of the document. CEMSS is a service offering in the Qwest network that facilitates wholesale access to new and existing basic network services. CEMSS offers a mediated service interface between Qwest regulated basic services and enhanced services (wholesale) providers that seek to use services supported on the CEMSS interface. CEMSS functions in conjunction with specific Qwest Advanced Intelligent Network (AIN) and network switch based services offered only on Nortel DMS100 and Lucent 5ESS switches. CEMSS can be utilized by enhanced service providers to receive notification of certain local PSTN (switch) call events, and invoke call control operations on Qwest switches. CEMSS also functions to manage end user voice services parameter settings and updates through data messaging between the CEMSS interface and enhanced service provider applications. CEMSS Call Control is based upon specific sections of the Parlay Group’s specification (Parlay Framework and Parlay Multi Party Call Control -MPCC). Service Parameter settings and updates capability is provided over two interface options. These include one based on a Common Object Request Broker Architecture (CORBA) based Qwest custom message set and another based on a Qwest proprietary version of the Simple Object Access Protocol (SOAP) Extensible Markup Language (XML) interface protocol.
Locations and Timing of Deployment	CEMSS interacts with a Complimentary Network Service (CNS), CEMSS Subscriber which is tariffed in 9 states (Arizona, Colorado, Idaho, Montana, New Mexico, Oregon, Utah, Washington, Wyoming) and is accessible via the CEMSS gateway located in Denver, Colorado.
