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 bandwidth.

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
