Many large enterprises that access high bandwidth data services from t
heir networks are using narrowband voice channels to mimic high bandwi
dth data lines. Data traffic is being transported by service providers
via their narrowband networks, which, in turn, causes congestion and
resource problems for the providers. The service providers, desiring a
more efficient use of their networks, would like to move this traffic
to an asynchronous transfer mode (ATI) network but do not want to for
ce their customers to change their access methods or lose valuable net
work features such as dialing plans. This paper proposes a network arc
hitecture that will preserve customers' present access methods, preser
ve the features to which they have become accustomed and aggregate the
high bandwidth traffic onto an ATM network. The heart of the solution
is a new element known as the broadband interworking gateway (BBIG) w
hich bridges the customer premises access to both the voice band netwo
rk and the ATM network. An implementation solution that modifies and e
nhances the present configuration of the 5ESS(R) switch is also propos
