IVAD Installation

  • Wholesaler: The two common responsibilities that define a wholesaler are that they bill the end user for the IVAD service and they take tier 1 support issues. Broadwing is responsible for provisioning, installing, and providing tier 2 & above support.

  • Sales Agent: An Agent is simply responsible for selling the service. Focal is responsible for everything else.

  • Standard Delivery Time: Within 30 days

  • Process: Broadwing coordinates installation with the end user. The end user will likely receive a phone call from the loop provider (e.g. Verizon, SBC) informing them that they are doing some wiring work on day X. After the local loop is accepted, Broadwing will then call the customer and schedule a technician to install the IVAD service. This will include connecting the T1 to the IAD, and installing & providing connectivity to a 66 punch down block if required.

  • End User Obligations: The End User is responsible for providing their own PC/desktop and LAN support as well as coordinating the connectivity of their end-user voice and data CPE to the Integrated Access Device (IAD). End User is also responsible for providing uninterrupted AC power to the IAD.

  • Focal Responsibilities

    • Data Services: Broadwing’s responsibility ends at the Ethernet port on the LAN-side of the IAD.

    • Line Side Voice Service: Broadwing will also install a punchdown block for two-wire voice line termination (where applicable), and terminate the lines from the IAD to the block. The customer is responsible for the proper connections on the other side of the block to the telephone stations.

    • Trunk Side Voice Service: Broadwing’s responsibility ends at the RJ45 port on the IAD

  • Service Activation and Billing: Billing will begin when the Customer’s circuit is tested and operational, and available for use based on the following criteria:

    • Internet connectivity through Broadwing’s Network has been established

    • Customer receives local dial tone from the voice switch;

  • Miscellaneous: Broadwing will implement the Service utilizing standard IP configurations (static routing) and activate the Network Address Translation on the IAD. Proper configuration within the Integrated Access Device (IAD) is critical to the performance of Service provided by Broadwing.
