We've Rounded Up 42 Of The Hottest
Next-Generation Switching Platforms
The original title of this roundup was "Voice/Data Switches &
IP-PBXs." But as we began to collect information on the plethora of
equipment that may be classified under that heading, we realized that using
only two phrases to describe these products would be limiting to their
manufacturers, and to the industry as a whole. The next-gen network is a
valuable investment for service providers and carriers, and the many
components that enable analog voice to be packetized for even part of its
transport journey are crucial elements in building this infrastructure.
When putting together this lengthy roundup, we looked at standard
Internet telephony gateways, softswitches, edge access devices, and even the
peripherals that allow these devices to perform their switching tasks. The
majority of the products can certainly be classified as voice/data switches
and IP-PBXs, but whether they sit at the customer premise, in the central
office, or somewhere on the edge of the public network cloud, they all
perform data conversion and transport functions that are critical to the
success of the next-gen network.
