This chapter introduces the Paradyne JetFusion
2208 and 2308 integrated
access devices (IADs) and describes their hardware and software.
As competition in the telecommunications market intensifies, carriers find
themselves under growing pressure to reduce network costs and deliver
differentiated, highly competitive services. In response to this challenge,
Paradyne provides a family of IADs that incorporates the capabilities of
multiple networking devices capable of supporting multiple networking
protocols such as TDM, Frame Relay, and ATM, and multiple applications
such as the integration of voice/data and high-speed internet access. By
consolidating multiple network devices, converging multiple services, and
moving intelligence to the network’s edge, Paradyne’s JetFusion 2200 and
2300 series IADs lower requirements for capital equipment, minimize
operational expenditures, and maximize carriers’ profits. Using JetFusion
IADs to integrate legacy networks into evolving infrastructures, service
providers can now also enable budget-constrained customers to leverage the
power of wide-area communications for competitive advantage. In particular,
these new services allow SMBs, often lacking the resources to install and
manage multiple communications devices, to compete effectively with their
larger counterparts in the global marketplace.
The JetFusion 2208 and 2308 IADs are access devices that terminate either a
T1- or DSL-based service, and provide the end user with the ability to send
and receive both voice calls and data transmissions via a single connection.
The connection may be either T1/E1 or SDSL. Models are equipped with up
to eight voice ports and an Ethernet interface with integrated routing protocols
and functionality.
Two versions of these IADs are offered: a base version that provides support
for VoATM only and an “s” version that provides all the features of the base
model plus support for MGCP and SIP. The built-in flexibility of the
JetFusion 2208 and 2308, supporting emerging protocols such as MGCP and
SIP, enables the IAD to evolve with the network, and provides an easily
managed, cost-effective migration to VoIP.

The “s” version of the JetFusion
2208 and 2308 provides a single unit solution that can support VoATM and
VoIP applications in a single unit. The 2208s also supports TDM. This
provides the user with CPE investment protection, reduced inventory and
VoIP applications in a single unit. The 2208s also supports TDM. This
