Verizon's Switched Access services provide two-point communications paths between the long distance carrier's Customer Designated Location (CDL) and the points of end user terminations within Verizon's Access Area. Each communications path is established through the use of Switched Transport, End Office Services and related Switched Access offerings. Switched Access can be provided via line side or trunk side connections to the service provider's facilities.

There are 4 types of Switched Access Services:

Feature Group A

Switched Access provides line-side interconnection to Verizon's end office switches through an end user seven-digit access code (NXX-XXXX) for the long distance customer's use in originating and terminating calls to end users.

Feature Group B

Switched Access provides trunk-side interconnection to Verizon's end office switches through a uniform seven digit access code (950-XXXX) for the long distance customer's use in originating and terminating calls to end users.

Feature Group C

Switched Access provides trunk-side interconnection to Verizon's end office switches for providers of MTS and WATS for originating and terminating communications.

Feature Group D

Switched Access provides trunk-side interconnection to Verizon's end office switches through either a 101XXXX arrangement or on a pre-subscribed basis for the long distance customer's use in originating and terminating calls to end users.

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

Verizon offers three types of Switched Access services: Feature Group A, Feature Group B and Feature Group D

Feature Group A

Service is a lineside connection, which is used primarily for Foreign Exchange access. It is ordered most often by large end users that wish to establish a local seven-digit telephone number for call completion to and from a foreign LATA. The end user enters a Personal Identification Number (PIN) to place a long distance call. Feature Group A is provisioned from the Verizon local switching center.

In addition to Foreign Exchange access, Feature Group A also provides Off Network Access Line (ONAL) and MTS/WATS services as well as IP Telephone Gateway Optional features include Hunt Group, Uniform Call Distribution (UCD), Queuing and Three Way Calling.

Feature Group B

Service is trunk side connection. It offers your customers the advantage of a single, nationwide phone number. This is available because the originating dialing codes are in the form of 950-XXXX. The XXXX digits are the unique Carrier Identification Code (CIC).

Automatic Number Identification (ANI) and Alternate Routing are available with this service. The terminating portion of Feature Group B can be a Verizon end office of Verizon access tandem.

Feature Group D

Service is a trunk side connection which is the most frequently used access service. It is the primary access media because it lets interexchange customers offer their subscribed customers the capability of using 1+ dialing for calling on their network. Feature Group D also permits 101XXXX calling, allowing end-users the ability to access an interexchange carrier other than their subscribed carrier. Automatic Number Identification (ANI) and Alternate Routing are available. Feature Group D can be ordered directly from the interexchange carrier's Point of Presence to either a Verizon end office or Verizon access tandem.

Switched Access is provided in conjunction with either of two types of access services, bundled Feature Groups or unbundled Basic Serving Arrangements (BSAs). BSAs are provided in two basic categories differentiated by their technical characteristics and how they connect, line side or trunk side connection, to the Telephone Company's first point of switching.

The trunk side BSA is further differentiated into three alternatives based upon how the end user accesses the trunk side BSA, with or without an access code. Feature Group A (FGA) and Basic Serving Arrangement A (BSA-A) are defined as line side connections to the Telephone Company's network.

Feature Group B (FGB), Feature Group D (FGD), Basic Serving Arrangement Alternative B (BSA-B), and Basic Serving Arrangement Alternative D (BSA-D) are defined as trunk side connections to the Telephone Company's network. The use of a line side or trunk side switched access connection is dependent upon the switched access arrangement ordered by the customer.

Feature Groups and BSAs are arranged for either originating, terminating, or two-way calling, based on the end office switching capacity ordered. Originating calling permits the delivery of calls from Telephone Company exchange service locations to the customer's premises.

Terminating calling permits the delivery of calls from the customer's premises to Telephone Company exchange service locations. Two-way calling permits the delivery of calls in both directions, but not simultaneously.

Switched Access Feature Group's are ordered in either quantities of lines or trunks or in Busy Hour Minutes of Capacity (BHMC). FGA and BSA-A is furnished on a per-line basis, and FGB, FGD, BSA-B, BSA-D and SAC Access Service are furnished on a per-trunk basis in accordance with the capacity ordered in trunks or BHMC.

Quantities of lines, trunks or total BHMC of the circuit group connecting the first point of switching and the CDL are determined at the Telephone Company's first point of switching. A customer may designate one or more CDLs within the LATA for FGA, FGB, FGD, BSA-A, BSA-B, BSA-D Switched Access or SAC Access Service.

Pricing

Rates and charges for Switched Access Service depend generally on its use by the customer and whether it is provided in a Telephone Company end office that is so equipped. There are three types of rates and charges that apply to Switched Access Service. These are monthly recurring rates, usage rates, and nonrecurring charges. These rates and charges are applied differently to the various rate elements as set forth in the appropriate state and federal tariffs.
