Architecture
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.
