| Switched
Access uses Verizon's local exchange network to transport
switched traffic between end-users and
1) Interexchange Carriers (IXCs),
2) Wireless Carriers or
3) Competitive Local Exchange Carriers (CLECs).
Types of Switched Access Services
Feature Group A (FGA)
FGA Service is a line side connection that 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
Local Access Transport Area (LATA). FGA is provisioned
from the Verizon local switching center.
In addition to Foreign Exchange access, FGA also
provides Off Network Access Line (ONAL) and Message
Telecommunications Service / Wide Area Telecommunications
Service (MTS/WATS) services. Optional features include
Hunt Group, Uniform Call Distribution (UCD), and Queuing.
Feature Group B (FGB)
FGB Service is a trunk side connection. It offers end-users
the advantage of being able to utilize services with
a single nationwide number. This service is made possible
by utilizing originating dialing codes in the form of
950-XXXX. The XXXX digits are the unique FGB Carrier
Identification Code (CIC) assigned to the Verizon Wholesale
customers.
The terminating portion of FGB can be ordered directly
from the IXC’s Point of Presence (POP) to either
a Verizon end office or Verizon access tandem.
Feature Group D (FGD)
FGD Service is a trunk side connection and is the most-commonly
requested access service. It is the primary access media
because it lets IXCs offer their subscribed customers
the capability of using 1+ dialing for calling on their
network. FGD also permits 101XXXX calling which allows
an end-user the ability to access an IXC other than
their subscribed carrier provided that the alternate
IXC offers FGD service in the end user’s calling
area.
Automatic Number Identification (ANI) and Alternate
Routing are also available. FGD can be ordered directly
from the IXC's POP to either a Verizon end office or
a Verizon access tandem.
Three Rate Categories for Switched
Access Services
1) Carrier Common Line recovers Verizon costs in providing
the telephone lines (also known as local loops) used for
making or receiving toll or long distance calls.
2) Local Switching recovers costs associated with Verizon's
end-office switching equipment.
3) Local Transport recovers costs associated with the
circuit termination equipment and facilities between Verizon's
end offices and the IXC's POP.
