				  the selective routing of calls to appropriate PSAPs in a traditional legacy 9-1-1
				  system.

				  together with associated plant used in furnishing telecommunications services in
				  that area. Exchanges are identified on exchange boundary maps on file with the
				  Commission.
"Forced disconnect" - A feature that allows the PSAP to release a
				  telephone connection, even though the calling party has not yet disconnected, to

				  architecture, so that i3 PSAPs are able to receive emergency calls from legacy
				  networks.
"Local loop" - A channel between a customer's network interface
				  and its serving central office. The most common form of loop, a pair of wires, is
				  also called a line.
"Master Street Address Guide" or "MSAG" - The computerized
				  geographical file that either consists of all street and address data or its
				  functional equivalent (i.e. geospatial data) within the 9-1-1 system area. This
				  database is the key to the selective routing capability of E9-1-1 systems. It
				  matches an originating caller to a specific answering point based on the address
				  data. The MSAG will require updating after the initial file is created.
"National Emergency Number Association" or "NENA" - The
				  international not-for-profit organization whose purpose is to lead, assist and
				  provide for the development, availability, implementation and enhancement of a
				  universal emergency telephone number or system common to all jurisdictions through
