Common use of SIGNALING AND INTERCONNECTION TRUNKING REQUIREMENTS Clause in Contracts

SIGNALING AND INTERCONNECTION TRUNKING REQUIREMENTS. 65.1 This Section sets forth certain signaling requirements and the terms and conditions for Interconnection provided by CenturyLink and CLEC and provides descriptions of the trunking requirements between CLEC and CenturyLink. This Section describes the required and optional trunk groups. 65.2 Signaling Parameters: CenturyLink and CLEC are required to provide each other the proper signaling information (e.g., originating Calling Party Number (CPN), Charge Number (ChN) and destination called party number, etc.) as required by Applicable Rules and further clarified by the FCC’s ICC Order to enable each Party to issue bills in a complete and timely fashion. All CCS signaling parameters will be provided unchanged including CPN, calling party category, ChN on all calls. All privacy indicators will be honored. Unless there is a waiver pending or the FCC has approved a waiver petition regarding specific technical restrictions, the ChN is to be passed unaltered in SS7 signaling fields where it is different than CPN and ChN must not be populated with a number associated with an intermediate switch, platform, or gateway, or other number that designates anything other than a calling party’s charge number. Where SS7 connections exist, each Party shall pass all CCS signaling parameters, where available, on each call carried over Interconnection trunks. The Parties will coordinate and exchange data as necessary to determine the cause of the CPN/ChN failure and to assist its correction. 65.3 The Parties shall use separate two-way Feature Group D trunks for the exchange of any traffic which is not Local Traffic, except for Toll VoIP-PSTN Traffic, IntraLATA LEC Toll Traffic and Jointly Provided Switched Access Service Traffic (as defined by MECAB and MECOD) and such trunks shall be ordered out of and subject to the applicable access Tariffs. In the event CLEC uses the Local Interconnection Trunks for any traffic in violation of this section, CenturyLink shall be entitled to seek injunctive relief and to recover damages, including without limitation, compensation for such traffic at the rates applicable to access traffic. 65.4 One Way and Two Way Trunk Groups. 65.4.1 The Parties agree to jointly establish, provision and maintain bi- directional two-way trunk groups for Local Traffic, Transit Traffic, VoIP-PSTN Traffic and IntraLATA LEC Toll Traffic that has not been routed to an IXC and separate two-way trunk groups for Jointly Provided Switched Access Traffic. Trunks will utilize SS7 signaling protocol. Multi-frequency (MF) signaling protocol may only be used where CLEC can demonstrate that it is not Technically Feasible to use SS7 or where CenturyLink otherwise agrees to use MF.
