This chapter introduces the 2208, 2304, 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 IADs lower
requirements for capital equipment, minimize operational expenditures, and
maximize carriers’ profits. Using the Paradyne 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 2208, 2304, 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 2208,
2304, 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 IADs 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 training requirements, as well as
