Typical Type 2 Interconnection
A Wireless Service Provider (WSP) establishes an
entrance into a Qwest End Office which then
becomes its Serving Wire Center (SWC). From that
SWC, a Type 2 Interconnection Facility is
extended to the Local Tandem which allows access
to all customers being served by all End Offices
subtending the Local Tandem within the Local
Calling Area via Qwests IOF trunking (aka common
trunks, or behind the tandem trunks). In
addition, a Type 2 Interconnection Facility is
extended to the Access/Toll Tandem which allows
for completion of toll calls (1 calls) over the
toll trunking network. With Type 2
Interconnection, the WSP obtains an NXX, or
a portion of an NXX as needed, that is assigned
to the MSC, and that is independent of
Qwests Network. An MSC functions as a Class 5
End office on the Public Switched Telephone
Network (PSTN) and is listed in the LERG.
