Unbundled Shared Trunk Ports
Overview
What It Is
Frontier's Unbundled Shared Trunk Port is a switch termination that is used in conjunction with our unbundled switch and shared Interoffice Facility (IOF) transport infrastructure. Service providers who use Frontier's unbundled switching can use this interface as a part of Unbundled Shared Transport. Unbundled Shared Trunk Ports are a necessary component of Unbundled Shared Transport and are not available as a separate service.
An Unbundled Shared Trunk Port provides the access needed to transport local, toll and access exchange traffic. But, that traffic must originate from your unbundled line port and terminate to other switches on which Verizon routes its own traffic.
How It Works
With this port, the features that Frontier uses for IOF transport are automatically available to you. The port has a DS1 bandwidth and supports 24 trunks at 56 Kbps each. When utilizing a shared trunk port traffic routing will follow the same routing as Verizon traffic, over a network comprised of end office and tandem switches.
Description
An unbundled trunk port is a Frontier-provided switch termination on a Frontier switch (i.e., end office or tandem). A trunk port is the physical electrical interface to the switch that terminates a trunk. It provides access to the functions and capabilities of the Frontier switch.
There are two types of unbundled trunk ports: dedicated and shared. A dedicated port serves as the interconnection between a Frontier unbundled switch and the service provide's collocation arrangement. This trunk port is dedicated to the use of a single service provider in its provisioning of local exchange and exchange access services. An unbundled shared trunk port serves as the interconnection between a Frontier unbundled switch and Frontier's unbundled shared Interoffice Facility (IOF) transport infrastructure.
Availability
Unbundled Shared Trunk Ports are available only in WV. Unbundled shared trunk ports cannot be ordered separately, but are provided as part of unbundled shared transport, available to service providers, which use Frontier's unbundled local switching. The service provider must inform Verizon during the Network Design Review (NDR) process whether calls originating from its unbundled line ports will be routed over unbundled shared IOF transport or unbundled dedicated transport.
Pricing
The service provider is charged on a per minute-of-use basis for calls originating from an unbundled line port routed through the Frontier shared IOF infrastructure.
Pricing and applicable USOCs may vary by state jurisdiction and pursuant to individual carrier interconnection agreements. See your federal and state tariffs for detailed information.
Features
Trunk features on an unbundled shared trunk port are provided automatically as they exist for Frontier's traffic using the same IOF transport.
Applications
The unbundled shared trunk port is used for access to Frontier's unbundled shared IOF infrastructure for the transport of local, toll, and access exchange traffic originating from the service provider's unbundled line port, and terminating to other Verizon switches, or other service provider switches on which Frontier has chosen to route its own traffic.
The unbundled shared trunk port has a DS1 bandwidth capable of supporting twenty-four 56 Kbps trunks. The unbundled shared trunk port is available, as Frontier has selected to route its own traffic, on the following Verizon switches:
