Where SS7 connectivity is available and required by the applicable PSAP, the Parties agree to implement CCS/SS7 trunks rather than CAMA (MF) trunks. 4.2.6 Carrier is responsible for appropriate diverse facilities if required by applicable State Commission rules and regulations or if required by other governmental, municipal, or regulatory authority with jurisdiction over 911 services. 4.2.7 Carrier shall engineer its 911 trunks to maintain a minimum P.01 grade of service as specified by NENA standards. 4.2.8 In order to implement Phase II E911 Service, Carrier is responsible for ordering a 56K or 64K frame relay or fractional T-1 circuit (“Data Circuit”) from Carrier’s MSC to the appropriate AT&T-13STATE ALI server where AT&T-13STATE is the designated ALI Database Provider. Such Data Circuit may be ordered from AT&T-13STATE affiliate or vendor of Carrier’s choice. 4.2.9 Carrier shall monitor its 911 circuits for the purpose of determining originating network traffic volumes. If ▇▇▇▇▇▇▇'s traffic study indicates that additional circuits are needed to meet the current level of 911 call volumes, Carrier shall request additional circuits from AT&T-13STATE. 4.2.10 Carrier will cooperate with AT&T-13STATE to promptly test all 911 trunks and facilities between Carrier’s network and the AT&T-13STATE 911 Selective Router(s) to assure proper functioning of 911 service. ▇▇▇▇▇▇▇ agrees that it will not pass live 911 traffic until both parties complete successful testing. 4.2.11 Carrier is responsible for the isolation, coordination and restoration of all 911 network maintenance problems to Carrier’s facility Meet Point. ▇▇▇▇▇▇▇ is responsible for advising AT&T-13STATE of the circuit identification and the fact that the circuit is a 911 circuit when notifying AT&T-13STATE of a failure or outage. The Parties agree to work cooperatively and expeditiously to resolve any 911 outage. AT&T-13STATE will refer network trouble to Carrier if no defect is found in AT&T- 13STATE’s 911 network. The Parties agree that 911 network problem resolution will be managed expeditiously at all times.
