VoATM and DSL

Because DSL links are ready-made for voice and data and ATM excels at carrying varied traffic, using VoATM over DSL over the local loop to the customer is a natural extension of these services.

To enable the combination of equipment that supports VoATM is needed at each end of the localloop: a next-generation integrated access device (NG-IAD) at the customer premises and a voice gateway at the CO.

The real benefit is that the telephone line that once carried a single phone call for voice, data, or fax traffic can now be expanded to carry data and voice simultaneously on the same pair of wires.

Because we use the data protocols (IP), we can multiplex several (16) conversations and Internet access on the higher bandwidth, and still have the lower end (0-4kHz) available as a full-time fax line. The use of the bandwidth that was once arbitrarily curtailed is now a reality.

The integrated access device concept is shown in the picture above.

The integrated devices can use many applications, as shown in the picture above.
