Switched Access Services – V2.0


Product Description


Switched Access Services, Brightspeed's most basic group of services, enables access customers, i.e., Interexchange Carriers (IXC), to complete end-user requests for intrastate or interstate long-distance calls.


Switched Access Service, which is available to customers for their use in furnishing their services to end users, provides a two-point electrical communications path between a customer’s premises and an end user’s premises. It provides for the use of terminating, switching, transport facilities and common subscriber plant of the Company. Switched Access Service provides for the ability to originate calls from an end user’s premises to a customer’s premises, and to terminate calls from a customer’s premises to an end user’s premises in the LATA where it is provided.

Identification and Rating of VoIP-PSTN Traffic


VoIP-PSTN Traffic is traffic exchanged between a Telephone Company end user and the customer in Time Division Multiplexing ("TDM") format that originates and/or terminates in Internet Protocol ("IP") format. The FCC Tariff governs the identification and compensation of VoIP-PSTN Traffic required by the Federal Communications Commission in its Report and Order in WC Docket Nos. 10-90, etc., FCC Release No. 11-161 (Nov 18,2011).


A customer may update their PVU factors quarterly using methods outlined in the FCC Tariff. If the customer submits factor updates, it must submit no later than 15 days after the first of January, April, July and/or October each year, based on data for the prior three months, ending the last day of December, March, June and September, respectively. The revised PVU factors will serve as the basis for future billing and will be effective the next bill date and shall serve as the basis for subsequent monthly billing until superseded by new PVU factors.


Quarterly PVU Factor Updates


A standard Brightspeed Factor for must be used for submitting Quarterly Factor updates to Brightspeed. The PIU/POM/PCL/PVU Quarterly Update Form can be found on the Brightspeed Wholesale Website.


Optional Features


Carrier Identification Parameter (CIP)


Carrier Identification Parameter, or CIP, is an optional switching feature which identifies and transmits the Carrier Identification Code (CIC) of the presubscribed carrier or the Access Code (101XXXX) dialed by the calling party to the customer as part of the Initial Address Message (IAM). CIP is available with originating CST3 and Feature Group D Switched Access Service from suitably equipped SS7 end offices and tandems on a per trunk basis.


CIP functionality allows the IXC to combine individual carriers or services on one trunk group between the End Office or Access Tandem and the IXC switches. The CIP allows the IXC to consolidate trunk groups by having the ability to identify the carrier or traffic type on the other end.


CIP is an optional SS7 parameter that supports Interexchange Carrier Interconnection using Integrated Services Digital User Part (ISUP) call signaling. The CIP is included in the SS7 Initial Address Message (IAM) used in ISUP connections. The ability to include the CIP must be present in Access Tandems and Equal Access End Offices that terminate on the IXC.


Depending upon the type of access tandem and the signaling used between the access tandem and the end office, CIP may or may not be available. In some instances, the access tandem can create the CIP even when it is not passed by the end office. There are other optional features available for Switching, Transport Termination and Line Termination. These optional features are described in Brightspeed Operating Companies F.C.C. Tariff, and applicable state tariffs.

Brightspeed Switched Access Service enables the carrier to offer the high quality voice connections that long-distance users expect from the PSTN (Public Switched Telephone Network), at reasonable rates. For example ABC Carrier offers a host of products to end-user customers, including 1+ interstate long-distance service, and wants a low MOU rate that enables access to multiple end-users within selected LATAs.
