Integrated Access Devices
If there's one thing we learned in putting together this roundup, it's that
no two integrated access devices are alike. Many offer similar features and
functionality, and most aim to deliver converged voice and data services to the
customer premise through a small convenient box that may be administered
remotely by service providers. But the number of end users that can be served,
and the types of voice and data transport supported by these customer premise
devices, vary greatly. One thing all of the devices listed below have in common
is the ability to deliver enhanced communication services from a remote location
inside the network to an end user -- while making the most of available
The equipment included in this roundup serves a broad range of needs in
scalability and transport capability. If sending voice over a packet connection
is your customer's main priority, perhaps an IAD bundled with quality of service
(QoS) monitoring and traffic prioritization is the right choice for you. Or
perhaps security is a major concern for you and your customers, and you are
looking for a device with a built-in firewall and network address translation
(NAT). Whatever your current or anticipated needs, this broad range of products
should give you a good overview of the types of IADs available for delivering
your valuable services to the customer premise
