This chapter introduces the 2000 Series 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 2000 Series IADs
lower requirements for capital equipment, minimize operational expenditures,
and maximize carriers’ profits. Using the 2000 Series 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 2000 Series IADs are access devices that terminate a network WAN, and
provide the end user with the ability to send and receive both voice calls and
data transmissions via a single connection. The network WAN connection
may be either T1, E1, SDSL, ADSL, or SHDSL. The High POTS Port models
have from 12 to 24 POTS ports that have metal housing and a Universal
Serial Interface (USI). The Low POTS Port models have from 4 to 8 POTS
ports that provide service via individual RJ11 ports. Low POTS Port models
are encased in a plastic housing. All models are equipped with a
10/100Base-T Ethernet interface with integrated routing protocols and
functionality.
The built-in flexibility of the 2000 Series, 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
2000 Series IADs provides a single unit solution that can support VoATM
and VoIP applications in a single unit. The 2208s, 2216s, and 2224s also
