  • Network Interconnection Architecture Each Party will plan, design, construct and maintain the facilities within their respective systems as are necessary and proper for the provision of traffic covered by this Agreement. These facilities include but are not limited to, a sufficient number of trunks to the point of interconnection with the tandem company, and sufficient interoffice and interexchange facilities and trunks between its own central offices to adequately handle traffic between all central offices within the service areas at a P.01 grade of service or better. The provisioning and engineering of such services and facilities will comply with generally accepted industry methods and practices, and will observe the rules and regulations of the lawfully established tariffs applicable to the services provided.

  • Integrated Digital Loop Carriers The feeder portion of some loops may be provide by means of Integrated Digital Loop Carrier (IDLC). IDLC provides a fiber optic cable transmission path that travels directly into BellSouth’s central office local switch. Where BellSouth uses IDLC ,if technically feasible and capacity does exist, BST will provide Al-Call with a Designed DS0 UVL by using alternative provisioning techniques including but not limited to such as “hairpinning” and DAC grooming. Alternative provisioning techniques will be provided at no additional cost to Al-Call . Hairpinning involves providing a DS0 signal from an IDLC-served loop to Al-Call ’s collocation equipment by using a dedicated pathway that traverses BellSouth’s central office switch. BellSouth will provide such DS0 signal to Al-Call by establishing a copper cross connect between the BellSouth switch and Al-Call ’s collocation equipment.

  • Network Interconnection 26.1 Interconnection between the networks of different SERVICE PROVIDERs shall be as per National Standards of CCS No.7 issued from time to time by Telecom Engineering Centre (TEC) and also subject to technical feasibility and technical integrity of the Networks and shall be within the overall framework of interconnection regulations issued by the TRAI from time to time. However, if situation so arises, INTERCONNECTION with R2MF signaling may be permitted by LICENSOR.

  • SS7 Network Interconnection 15.1.1 Definition SS7 Network Interconnection is the interconnection of US LEC local Signaling Transfer Point Switches (STP) and US LEC local or tandem switching systems with BellSouth STPs. This interconnection provides connectivity that enables the exchange of SS7 messages among BellSouth switching systems and databases (DBs), US LEC local or tandem switching systems, and other third-party switching systems directly connected to the XxxxXxxxx XX0 network.
