Tandem Trunking Sample Clauses
The Tandem Trunking clause defines the rules and procedures for routing telecommunications traffic through intermediate switching points, known as tandem switches, rather than directly between originating and terminating points. In practice, this clause specifies when and how calls or data transmissions are routed via these tandem trunks, often to optimize network efficiency or manage capacity. For example, if direct trunk lines are unavailable or congested, traffic may be rerouted through a tandem switch to reach its destination. The core function of this clause is to ensure reliable and efficient network operation by providing alternative routing options, thereby reducing the risk of service interruptions and optimizing resource use.
Tandem Trunking. AT&T SOUTHEAST REGION 9-STATE
4.3.3.3.1 Section 251(b)(5)/IntraLATA Toll Traffic shall be routed on Local Interconnection Trunk Groups established at each AT&T SOUTHEAST REGION 9-STATE Access Tandem in the LATA where CLEC homes its NPA/NXX codes for calls destined to or from all AT&T SOUTHEAST REGION 9-STATE End Offices that subtend the designated Tandem. These trunk groups shall be one-way except where two-way trunks have been mutually agreed and will utilize SS7 signaling. Where CLEC does not interconnect at every Access Tandem switch location in the LATA, CLEC must use Multiple Tandem Access (MTA) to route traffic to End Users through those Tandems within the LATA to which CLEC is not interconnected. To utilize MTA, CLEC must establish Local Interconnection Trunk Groups to a minimum of one (1) Access Tandem within each LATA as required. AT&T SOUTHEAST REGION 9-STATE will route CLEC originated 251(b)(5)/IntraLATA Toll traffic for LATA-wide transport and termination. Compensation for MTA is described in Section 6.2.9 below.
Tandem Trunking. Where CenturyLink has a Tandem Switch, the Parties shall establish Tandem Trunking for the exchange of Local Traffic, IntraLATA Toll Traffic, Transit Traffic, Jointly Provided Switched Exchange Access Traffic and ISP Bound Traffic pursuant to Section 3.3.2.8.
Tandem Trunking. Interconnection at the Tandem for Local, InterLATA Toll, and/or IntraLATA Toll Traffic
Tandem Trunking. Multiple Tandem LATAs
4.4.5.1 Where SBC-AMERITECH has more than one Access Tandem in a LATA and AT&T elects a Tandem interconnection, IntraLATA Toll and Local traffic shall be combined on a single Local Interconnection Trunk Group at every SBC-AMERITECH Tandem for calls destined to or from all End Offices that subtend each Tandem.
Tandem Trunking. Where UNION has a Tandem switch in a LATA, the Parties may establish Tandem trunking for the exchange of intraLATA Toll Traffic, Local Traffic, and/or Tandem Transit Traffic for calls destined to or from end offices that subtend UNION’s tandem. The trunk group(s) shall be one-way or two-way and will utilize Signaling System 7 (“SS7”) signaling.
Tandem Trunking. AT&T MIDWEST REGION 5-STATE and AT&T WEST REGION 2-STATE
4.3.3.1.1 Section 251(b)(5) and ISP Bound Traffic shall be routed on Local Only Trunk Groups established at all AT&T MIDWEST REGION 5-STATE and AT&T WEST REGION 2- STATE Local Only Tandems in the LATA for calls destined to or from all AT&T MIDWEST REGION 5-STATE End Offices that subtend the designated Tandem. These trunk groups shall be two-way and will utilize SS7 signaling.
4.3.3.1.2 In AT&T MIDWEST REGION 5-STATE and AT&T WEST REGION 2-STATE all Section 251(b)(5)/IntraLATA Toll Traffic shall be routed on two-way Local Interconnection Trunk Groups using SS7 signaling. These trunk groups shall be established at all Local/IntraLATA and Local/Access Tandem switches in AT&T MIDWEST REGION 5-STATE and at the Access Tandem Switches in AT&T WEST REGION 2-STATE in the LATA, for calls destined to or from End Offices that subtend each Tandem.
Tandem Trunking. Multiple Tandem LATAs
5.3.2.1 Where SBC CALIFORNIA, SBC NEVADA, SBC CONNECTICUT or SBC MIDWEST REGION 5-STATE has more than one Access Tandem Switch and/or Local/IntraLATA Tandem Switch in a LATA, the Parties shall establish a single Local Interconnection Trunk Group at every SBC CALIFORNIA, SBC NEVADA, SBC CONNECTICUT or SBC MIDWEST REGION 5-STATE Tandem(s) where LEVEL 3 Offers Service within the area served by that tandem for calls destined to or from all SBC End Offices that subtend each Tandem in the LATA.
