ABSTRACT: This document provides generic technical requirements and protocols for the interconnection of a Wireless Services Provider (WSP) with
a Local Exchange Carrier (LEC) landline network. This GR describes signals, conditions, and events that generally occur at an
interface between a LEC and a WSP. This GR reflects the newer and broader application of interconnection arrangements that apply to
the WSP-LEC interface, subject to state and federal regulations. Interconnection changes have occurred with the passage of the
Telecommunications Act of 1996. As a result, some LECs are offering interconnection alternatives with varying traffic types, calling
scope, and routing. Issue 2 describes connections that were not discussed in Issue 1.
Issue 2 also describes the implications of Phase 1 of the FCC's plan for Emergency Services wireless calling. This GR describes
CLASS features as an example of SS7-specific applications that may be supported between a LEC and a WSP over the Type S interface. It
contains a discussion of the FCC-ordered implementation of LNP for LEC and WSP carriers within a specific timetable.
