Common use of Operations Support Systems for Trunk-Side Interconnection Clause in Contracts

Operations Support Systems for Trunk-Side Interconnection. 1.1.1 DTI will be able to order trunk-side interconnection services and facilities from GTE through a direct electronic interface over the GTE Network Data Mover ("NDM") in a nondiscriminatory manner. Orders for trunk-side interconnection will be initiated by an Access Service Request ("ASR") sent electronically by DTI over the NDM. ASRs for trunk-side interconnection will be entered electronically into GTE's Carrier Access Management System ("CAMS") to validate the request, identify any errors, and resolve any errors back to DTI. CAMS is a family of GTE systems comprised primarily of EXACT/TUF, SOG/SOP, and CABS. 1.1.2 The use of CAMS to support DTI's requests for trunk-side interconnection will operate in the following manner: GTE will route the ASR through its data center to one of two National Access Ordering Centers ("NACC"). The ASR will be entered electronically into the EXACT/TUF system for validation and correction of errors. Errors will be referred back to DTI. DTI then will correct any errors that GTE has identified and resubmit the request to GTE electronically through a supplemental ASR, without penalty or charge (e.g., order modification charge) to DTI. Similarly, errors committed by GTE subsequent to the receipt of a valid ASR from DTI will be expeditiously identified and corrected by GTE without the need for DTI's submission of a supplemental ASR. GTE then will translate the ASR into a service order for provisioning and billing. In order to convert the ASR into a service order, GTE personnel must apply the necessary elements to provision the service and include the billable elements necessary for GTE to bill XXX for the services provided. This application also requires a determination of the access tandem to end office relationships with the service requested. 1.1.3 At the next system level, translated service orders will be distributed electronically through the SOG/SOP systems to several destinations. The SOG/SOP system will begin the actual provisioning of the service for DTI. Other GTE provisioning systems are CNAS and ACES. The GTE Database Administrative Group ("DBA") and the Special Services Control Center ("SSCC") will be the two most important destinations at this level. The DBA location will identify codes for the appropriate 146 GTE switch in order to provide the functions required by the ASR. The SSCC will provide the engineering for the facilities over which the services will be handled. Information from these two groups (and others) then will be transmitted electronically to GTE's field service personnel (Customer Zone Technicians or "CZTs") who will establish the trunks and facilities, thus connecting the GTE facilities to a connecting company, if one is required, and to DTI. GTE's CZTs also will contact DTI directly to perform testing , and upon acceptance by DTI, will make the necessary entries into the GTE system to complete the order. The completed orders then will pass to GTE's Carrier Access Billing System ("CABS") which will generate the bill xx DTI. The billing process under CABS requires coordination with several other systems. 1.1.4 Billing for transport and termination services cannot be accomplished without call records from GTE's central office switches. Records of usage will be generated at GTE's end office switches or the access tandems. Call usage records will be transmitted electronically from GTE's switches through GTE's Billing Intermediate Processor ("BIP"). This system will collect the call records, perform limited manipulations to the record and transfer them to a centralized data center where they will be processed through the Universal Measurement System ("UMS") to determine the validity and accuracy of the records. UMS also will sort the records and send them to the CABS billing system, from which GTE will produce a bill xxx send it to DTI.

ASRs for trunk-side interconnection will be entered electronically into GTE's Carrier Access Management System ("CAMS") to validate the request, identify any errors, and resolve any errors back to DTITallgrass. CAMS is a family of GTE systems comprised primarily of EXACT/TUF, SOG/SOP, and CABS. 1.1.2 The use of CAMS to support DTITallgrass's requests for trunk-side interconnection will operate in the following manner: GTE will route the ASR through its data center to one of two National Access Ordering Centers ("NACC"). The ASR will be entered electronically into the EXACT/TUF system for validation and correction of errors. Errors will be referred back to DTITallgrass. DTI Tallgrass then will correct any errors that GTE has identified and resubmit the request to GTE electronically through a supplemental ASR, without penalty or charge (e.g., order modification charge) to DTITallgrass. Similarly, errors committed by GTE subsequent to the receipt of a valid ASR from DTI Tallgrass will be expeditiously identified and corrected by GTE without the need for DTITallgrass's submission of a supplemental ASR. GTE then will translate the ASR into a service order for provisioning and billing. In order to convert the ASR into a service order, GTE personnel must apply the necessary elements to provision the service and include the billable elements necessary for GTE to bill XXX xxxx Tallgrass for the services provided. This application also requires a determination of the access tandem to end office relationships with the service requested. 1.1.3 At the next system level, translated service orders will be distributed electronically through the SOG/SOP systems to several destinations. The SOG/SOP system will begin the actual provisioning of the service for DTITallgrass. Other GTE provisioning systems are CNAS and ACES. The GTE Database Administrative Group ("DBA") and the Special Services Control Center ("SSCC") will be the two most important destinations at this level. The DBA location will identify codes for the appropriate 146 GTE switch in order to provide the functions required by the ASR. The SSCC will provide the engineering for the facilities over which the services will be handled. Information from these two groups (and others) then will be transmitted electronically to GTE's field service personnel (Customer Zone Technicians or "CZTs") who will establish the trunks and facilities, thus connecting the GTE facilities to a connecting company, if one is required, and to DTITallgrass. GTE's CZTs also will contact DTI Tallgrass directly to perform testing testing, and upon acceptance by DTITallgrass, will make the necessary entries into the GTE system to complete the order. The completed orders then will pass to GTE's Carrier Access Billing System ("CABS") which will generate the bill xx DTIxxxx to Tallgrass. The billing process under CABS requires coordination with several other systems. 1.1.4 Billing for transport and termination services cannot be accomplished without call records from GTE's central office switches. Records of usage will be generated at GTE's end office switches or the access tandems. Call usage records will be transmitted electronically from GTE's switches through GTE's Billing Intermediate Processor ("BIP"). This system will collect the call records, perform limited manipulations to the record and transfer them to a centralized data center where they will be processed through the Universal Measurement System ("UMS") to determine the validity and accuracy of the records. UMS also will sort the records and send them to the CABS billing system, from which GTE will produce a bill xxx xxxx and send it to DTITallgrass.
