or structure. They simply regard the data as an arbitrary bit stream. All data bits are simply
transported to a defined destination encapsulated in IP/MPLS packets. Some primary applications
(Figure 2) include:
Transporting 2G and 3G network traffic over packet networks, for mobile operators. Mobile
service providers are implementing High-Speed Data Networks (HSxPA) to support new
revenue-generating services. The SPA is uniquely positioned for multigenerational
migration of mobile networks (2G and 3G), simultaneously carrying TDM and ATM traffic
over IP/MPLS networks. This technology provides a mechanism to enable IP/MPLS to the
cell site, which can eventually be in place to transport the mobile traffic over IP from end to
end.
T1/E1 circuit emulation for leased-line replacement.
PBX to PBX connectivity over PSN.
High-density SS7 backhaul over IP/MPLS.
Inter-MSC connectivity.
Preencrypted data for government, defense, or other high-security applications.
Proprietary synchronous or asynchronous data protocols used in transportation, utilities,
and other industries.
Leased-line emulation service offerings in metropolitan (metro) Ethernet or WAN service
provider environments.

ATM Applications
Service Provider Infrastructures
The SPA can be deployed for ATM service, which provides high-performance interconnectivity,
metro, and intra-POP applications between service provider POPs for IP/MPLS transport. It can
also be deployed as customer premises equipment (CPE) to provide the data component to the
service provider networks.
The ATM service allows service providers to effectively manage the bandwidth at the edges of the
network while implementing value-added Layer 3 services. Advanced traffic management features
(such as per-VC and per-VP traffic shaping) can also be used to help ensure that traffic from one
customer does not affect traffic from another.
With advanced traffic shaping features and support for many ATM service classes, the SPA can be
widely deployed in many parts of the service provider network. (See Figure 3.)
