  • Loop Provisioning Involving Integrated Digital Loop Carriers 2.6.1 Where Freedom has requested an Unbundled Loop and BellSouth uses IDLC systems to provide the local service to the End User and BellSouth has a suitable alternate facility available, BellSouth will make such alternative facilities available to Freedom. If a suitable alternative facility is not available, then to the extent it is technically feasible, BellSouth will implement one of the following alternative arrangements for Freedom (e.g. hairpinning): 1. Roll the circuit(s) from the IDLC to any spare copper that exists to the customer premises. 2. Roll the circuit(s) from the IDLC to an existing DLC that is not integrated. 3. If capacity exists, provide "side-door" porting through the switch. 4. If capacity exists, provide "Digital Access Cross Connect System (DACS)- door" porting (if the IDLC routes through a DACS prior to integration into the switch). 2.6.2 Arrangements 3 and 4 above require the use of a designed circuit. Therefore, non- designed Loops such as the SL1 voice grade and UCL-ND may not be ordered in these cases. 2.6.3 If no alternate facility is available, and upon request from Freedom, and if agreed to by both Parties, BellSouth may utilize its Special Construction (SC) process to determine the additional costs required to provision facilities. Freedom will then have the option of paying the one-time SC rates to place the Loop.

  • DTC DIRECT REGISTRATION SYSTEM AND PROFILE MODIFICATION SYSTEM (a) Notwithstanding the provisions of Section 2.04, the parties acknowledge that the Direct Registration System (“DRS”) and Profile Modification System (“Profile”) shall apply to uncertificated American Depositary Shares upon acceptance thereof to DRS by DTC. DRS is the system administered by DTC pursuant to which the Depositary may register the ownership of uncertificated American Depositary Shares, which ownership shall be evidenced by periodic statements issued by the Depositary to the Owners entitled thereto. Profile is a required feature of DRS which allows a DTC participant, claiming to act on behalf of an Owner of American Depositary Shares, to direct the Depositary to register a transfer of those American Depositary Shares to DTC or its nominee and to deliver those American Depositary Shares to the DTC account of that DTC participant without receipt by the Depositary of prior authorization from the Owner to register such transfer. (b) In connection with and in accordance with the arrangements and procedures relating to DRS/Profile, the parties understand that the Depositary will not verify, determine or otherwise ascertain that the DTC participant which is claiming to be acting on behalf of an Owner in requesting a registration of transfer and delivery as described in subsection (a) has the actual authority to act on behalf of the Owner (notwithstanding any requirements under the Uniform Commercial Code). For the avoidance of doubt, the provisions of Sections 5.03 and 5.08 shall apply to the matters arising from the use of the DRS. The parties agree that the Depositary’s reliance on and compliance with instructions received by the Depositary through the DRS/Profile System and in accordance with this Deposit Agreement shall not constitute negligence or bad faith on the part of the Depositary.
