Hosted Telecom Databases

LNP

Local number portability (LNP) is a mandate passed by
both the United States and Canadian governments, that
allow individuals to keep their existing telephone numbers
when moving between carriers. When a number is ported,
it is assigned a local routing number (LRN). This LRN is
linked to the carrier that manages the number and can be
changed, while the dialed telephone number cannot be.

The Peeredge Datasource Fabric enables limitless access to
the LNP database, through our licensed interconnection
with Neustar, the only third-party administrator of NPAC
data.

LERG

The LERG Routing Guide is primarily
designed to be used for routing of calls
by service providers (wireless, wireline,
inter and intra exchange, etc.). It also
supports functions such as networking
planning and engineering, numbering
administration, and is used by
companies, including many outside of
the telecommunications industry, to
support a wide range of business
operations and planning needs. 

The LERG has been in existence since 1984,
and provides for a common basis for service
providers within the NANP to directly report
their numbering and routing information.

LCAD

Local Calling Area Database

The Local Calling Area Database identifies North American local exchange carriers’ local calling areas by Rate Center. This local
calling area data in conjunction with the LERG database can be
used to determine local call status between any two North
American telephone exchange (i.e. NPA NXX) combinations by
cross-referencing the originating and terminating NPA NXX pair
to their associated Rate Center.

The local calling data is based (largely) on those local calling areas defined by the incumbent wireline local exchange carrier. There are
no attempt or calls per second limitations on the Peeredge Datasource Fabric and the service has native high-availability and automatically self-heals.
