Common use of INTERCONNECTION AND RECIPROCAL COMPENSATION Clause in Contracts

INTERCONNECTION AND RECIPROCAL COMPENSATION. 4.1 AT&T may choose to deliver both Local Traffic and toll traffic over the same trunk group(s), pursuant to the provisions of Attachment 15. In the event AT&T chooses to deliver both types of traffic over the same traffic exchange trunks, and desires application of the local call transport and termination rates, it will provide Percent Local Usage (“PLU”) information to BA as set forth in Attachment 15. In the event AT&T includes both interstate and intrastate toll traffic over the same trunk, it will provide Percent Interstate Usage (“PIU”) to BA as set forth in Attachment 15. BA shall have the same options, and to the extent it avails itself of them, the same obligation, to provide PIU and PLU information to AT&T. 4.2 Compensation for the exchange of Local Traffic is set forth in Table 1 of this Attachment and shall be assessed on a per minute-of-use basis for the transport and termination of such traffic. 4.3 When the Interconnection is at a BA tandem office switch, AT&T shall pay BA the rates for Tandem Termination as set forth in Table 1. BA will pay AT&T a reciprocal and symmetrical compensation rate for the termination of traffic at an AT&T tandem switch, or for the termination of traffic at AT&T’s single combined Class 4/Class 5 switch, for as long as AT&T maintains a single level switching and interconnection point hierarchy. Thereafter, the pricing in Section 4.5.1 below shall apply. When the Interconnection is at an AT&T collocated remote switching module, BA shall pay AT&T the End Office Termination rate as set forth in Table 1. 4.4 AT&T may choose to establish trunking to any given end office when there is sufficient Local Traffic to route calls directly to such end office. If AT&T leases non-shared trunks from BA, AT&T will pay the transport charges for dedicated transport. To the extent shared trunks are used, the charges will be shared by both Parties in proportion to their respective use of the shared trunk facility as mutually agreed for each trunking facility. 4.5 When the interconnection is at the BA end office, BA will pay AT&T compensation based on Tandem Termination when BA originated calls are terminated to AT&T’s subscribers through the termination of traffic at an AT&T tandem switch, or through the termination of traffic at AT&T’s single combined Class 4/Class 5 switch for as long as AT&T maintains a single level switching and interconnection point hierarchy. Thereafter, the pricing in Section 4.5.1 below shall apply. For calls originating on AT&T’s network and terminating to BA subscribers, AT&T will pay BA call termination compensation based on End Office Termination only. 4.5.1 At such time as AT&T offers any other Telecommunications Carrier access to its network at both the tandem (or functional equivalent) level and at the end office (or functional equivalent) level for the termination of Local Traffic, toll traffic, or switched exchange access traffic, it will immediately make such two-tiered interconnection available to BA for the termination of Local Traffic. At such time as BA delivers traffic to AT&T at two (2) levels in AT&T’s switching hierarchy (or functional equivalent), BA-originated Local Traffic delivered to AT&T at the AT&T tandem (or functional equivalent) shall incur the same Tandem Termination rate that BA charges and BA-originated Local Traffic delivered to AT&T at the AT&T end office (or functional equivalent) shall incur the same End Office Termination rate that BA charges. 4.6 Compensation for the termination of toll traffic and the origination of 800 traffic (except that 800 traffic which terminates locally) between the interconnecting Parties shall be based on the applicable exchange access charges in accordance with Applicable Law. 4.7 Where toll traffic is completed through the donor Party’s INP arrangement (e.g., remote call forwarding, flexible DID, etc.) to the porting Party’s subscriber, the porting Party shall be entitled to exchange access charges collected by the donor Party, but applicable to the functions performed by the porting Party in accordance with Applicable Law. 4.8 AT&T shall pay a tandem transit rate and/or dedicated transport rates, as applicable, as set forth in Table 1 of this Attachment when AT&T uses BA facilities to terminate local traffic to a third party Telecommunications Carrier. BA shall pay AT&T an equivalent tandem transit rate and/or dedicated transport rates, as applicable, when BA uses AT&T facilities to terminate local traffic to a third party Telecommunications Carrier.

INTERCONNECTION AND RECIPROCAL COMPENSATION. 4.1 AT&T may choose to deliver both Local Traffic and toll traffic over the same trunk group(s), pursuant to the provisions of Attachment 15.

BA will pay AT&T a reciprocal and symmetrical compensation rate for the termination of traffic at an AT&T tandem switch, or for the termination of traffic at AT&T’s single combined Class 4/Class 5 switch, for as long as AT&T maintains a single level switching and interconnection point hierarchy. Thereafter, the pricing in Section 4.5.1 below shall apply. When the Interconnection is at an AT&T collocated remote switching module, BA shall pay AT&T the End Office Termination rate as set forth in Table 1. 4.4 AT&T may choose to establish trunking to any given end office when there is sufficient Local Traffic to route calls directly to such end office. If AT&T leases non-non- shared trunks from BA, AT&T will pay the transport charges for dedicated transport. To the extent shared trunks are used, the charges will be shared by both Parties in proportion to their respective use of the shared trunk facility as mutually agreed for each trunking facility. 4.5 When the interconnection is at the BA end office, BA will pay AT&T compensation based on Tandem Termination when BA originated calls are terminated to AT&T’s subscribers through the termination of traffic at an AT&T tandem switch, or through the termination of traffic at AT&T’s single combined Class 4/Class 5 switch for as long as AT&T maintains a single level switching and interconnection point hierarchy. Thereafter, the pricing in Section 4.5.1 below shall apply. For calls originating on AT&T’s network and terminating to BA subscribers, AT&T will pay BA call termination compensation based on End Office Termination only. 4.5.1 At such time as AT&T offers any other Telecommunications Carrier access to its network at both the tandem (or functional equivalent) level and at the end office (or functional equivalent) level for the termination of Local Traffic, toll traffic, or switched exchange access traffic, it will immediately make such two-tiered interconnection available to BA for the termination of Local Traffic. At such time as BA delivers traffic to AT&T at two (2) levels in AT&T’s switching hierarchy (or functional equivalent), BA-originated Local Traffic delivered to AT&T at the AT&T tandem (or functional equivalent) shall incur the same Tandem Termination rate that BA charges and BA-originated Local Traffic delivered to AT&T at the AT&T end office (or functional equivalent) shall incur the same End Office Termination rate that BA charges. 4.6 Compensation for the termination of toll traffic and the origination of 800 traffic (except that 800 traffic which terminates locally) between the interconnecting Parties shall be based on the applicable exchange access charges in accordance with Applicable Law. 4.7 Where toll traffic is completed through the donor Party’s INP arrangement (e.g., remote call forwarding, flexible DID, etc.) to the porting Party’s subscriber, the porting Party shall be entitled to exchange access charges collected by the donor Party, but applicable to the functions performed by the porting Party in accordance with Applicable Law. 4.8 AT&T shall pay a tandem transit rate and/or dedicated transport rates, as applicable, as set forth in Table 1 of this Attachment when AT&T uses BA facilities to terminate local traffic to a third party Telecommunications Carrier.
