Common use of Trunking Requirements Clause in Contracts

Trunking Requirements. In accordance with Article III, Section 12, it will be necessary for the Parties to have met and agreed on trunking availability and requirements in order for the Parties to begin exchange of traffic. 4.3.1. The Parties agree to establish trunk groups of sufficient capacity from the interconnecting facilities such that trunking is available to any switching center designated by either Party, including end offices, tandems, 911 routing switches, and directory assistance/operator service switches. The Parties will mutually agree where one-way or two-way trunking will be available. The Parties may use two-way trunks for delivery of Local Traffic or either Party may elect to provision its own one-way trunks for delivery of Local Traffic to the other Party.

The Parties may use two-way trunks for delivery of Local Traffic upon mutual agreement or either Party may elect to provision its own one-way trunks for delivery of Local Traffic to the other Party. If a Party elects to provision its own one-way trunks, that Party will be responsible for its own expenses associated with the trunkstrunks and the other Party will make trunk ports available. Each Party must have sufficient capacity at its switches to handle the traffic of the other Party and to maintain at least B.01 grade of service. 4.3.2. TOUCHTONE shall make available to GTE trunks over which GTE shall terminate to end-users of TOUCHTONE-provided Exchange Services, Local Traffic and intraLATA toll or optional EAS traffic originated from end-users of GTE-provided Exchange Service. 4.3.3.

TOUCHTONE AWS and GTE will support the provisioning of trunk groups Trunk Groups that carry combined or separate Local Traffic and intraLATA toll and optional EAS traffic. GTE requires separate trunk groups Trunk Groups from TOUCHTONE AWS to originate and terminate interLATA calls and to provide Switched Access Service to IXCs. To the extent TOUCHTONE desires to have any IXCs originate or terminate switched access traffic to or from TOUCHTONE, using jointly provided switched access facilities routed through a GTE access tandem, it is the responsibility of TOUCHTONE to arrange for such IXC to issue an ASR to GTE to direct GTE to route the traffic. If GTE does not receive an ASR from the IXC, GTE will initially route the switched access traffic between the IXC and TOUCHTONE. If the IXC subsequently indicates that it does not want the traffic routed to or from TOUCHTONEAWS, GTE will not route the traffic. 4.3.3.1 4.3.2.1 Each Party agrees to route traffic only over the proper jurisdictional trunk groupTrunk Group. 4.3.3.2 4.3.2.2 Each Party shall only deliver traffic only over the local interconnection trunk groups Trunk Groups to the other Party's access tandem switching center (Tandem or MSC) for those publicly-dialable NXX Codes served by end offices End Offices that directly subtend the access tandem Tandem or to those wireless service providers other Local Providers that directly subtend the access tandemTandem. 4.3.3.3 4.3.2.3 Neither party Party shall route Switched Access Service traffic over local interconnection trunks, or Local Traffic over Switched Access Service trunks. 4.3.3 The Parties will work together to establish high usage End-Office Trunk Groups. 4.3.4 AWS will provide Percent Local Usage (“PLU”) factors on a semi-annual basis to identify the proper jurisdiction (local or non-local) of each call type that is carried over the local Interconnection Facilities. If these percentages are not received semi-annually, the Parties shall use the last previous reported percentages. The initial PLU factor is identified as the Percent Local Usage Factor on Appendix A. 4.3.5 Reciprocal traffic exchange arrangement trunk connections shall be made at a DS-1 or multiple ▇▇-▇ ▇▇▇▇▇, ▇▇-▇, (SONET where technically available) and shall be jointly-engineered to the appropriate industry grade of service standard (B.01 or B.005). 4.3.6 AWS and GTE agree to use diligent efforts to develop and agree on a Joint Interconnection Grooming Plan prescribing standards to ensure that the reciprocal traffic exchange arrangement Trunk Groups are maintained at consistent B.01 or better grades of service. Such plan shall also include mutually-agreed upon default standards for the configuration of all segregated Trunk Groups. 4.3.7 SS7 Common Channel Signaling will be used to the extent that such technology is available. If SS7 is not available, Multi-Frequency Signaling (MF) will be used as specified. 4.3.8 The Parties agree to offer and provide to each other B8ZS Extended Superframe Format ("ESF") facilities, where available, capable of voice and data traffic transmission. 4.3.9 The Parties will support intercompany 64kbps clear channel where available.

Trunking Requirements. In accordance with Article III, Section 12, it will be necessary for the Parties to have met and agreed on trunking availability and requirements in order for the Parties to begin exchange of traffic. 4.3.1. The Parties agree to establish trunk groups of sufficient capacity from the interconnecting facilities such that trunking is 4.3.1 GTE shall make trunks available to any switching center designated by either PartyACS over which ACS shall terminate to end users of GTE-provided Exchange Services, including traffic originated from end offices, tandems, 911 routing switches, and directory assistance/operator service switches. The Parties will mutually agree where oneusers of ACS-way or provided two-way trunking will be available. The Parties may use two-way trunks for delivery of Local Traffic or either Party may elect to provision its own one-way trunks for delivery of Local Traffic to the other Party. If a Party elects to provision its own one-way trunks, that Party will be responsible for its own expenses associated with the trunkswireless mobile telecommunications services. 4.3.2. TOUCHTONE 4.3.2 ACS shall make trunks available to GTE trunks over which GTE shall terminate to end-end users of TOUCHTONEACS-provided Exchange Servicestwo-way wireless mobile services, Local Traffic and intraLATA toll or optional EAS traffic originated from end-end users of GTE-provided Exchange Service. 4.3.3. TOUCHTONE 4.3.3 ACS and GTE shall, where applicable, make reciprocally available, by mutual agreement, the required trunk groups to handle different traffic types. TOUCHTONE ACS and GTE agree to work cooperatively to agree on network trunking within sixty (60) days following full execution of this Agreement. ACS and GTE will support the provisioning of trunk groups that carry combined or separate Local Traffic and intraLATA toll and optional EAS traffic. GTE requires separate trunk groups from TOUCHTONE to originate and terminate interLATA calls and ACS to provide Switched Access Service to IXCs. To the extent TOUCHTONE desires to have any IXCs originate or terminate switched access traffic to or from TOUCHTONE, using jointly provided switched access facilities routed through a GTE access tandem, it is the responsibility of TOUCHTONE to arrange for such IXC to issue an ASR to GTE to direct GTE to route the traffic.
