The modern packet-based local access network enables Integrated Communication Providers (ICPs) to deliver a combination of voice and data services to their subscribers over the local loop.

Our Voice-over-Broadband (VoBB) local access network alternatives (Figure 1–1) include:

	￿	Voice over DSL (VoDSL)—enables the delivery of
		integrated high-speed voice and data services over a single
		DSL circuit; that is, over a single copper pair.
		Voice over T1 (VoT1)—offers access at greater distances
		(i.e., hundreds of miles when repeaters are used) and
		provides guaranteed bandwidth. It also uses existing T1
		aggregation resources at the ILEC central office.
		Voice over Wireless (VoWLL)—eliminates the need for
		land line copper loops by using ATM over MMDS or U-NII
	￿	wireless broadband access networks.
