How It Works
An Integrated Access Device (IAD) aggregates all local, long distance and Internet access traffic services across the Lightyear XSTREAM Dynamic T1 circuit. The IAD interfaces with existing phone system (POTS, PRI or IP-based). The IAD also enables the existing data LAN to provide Internet access via an Ethernet handoff.
As simultaneous calls are placed, the Internet bandwidth is dynamically allocated to voice users to ensure calls are a priority. If several calls made, more bandwidth is set aside for voice traffic. If there is no voice traffic, the entire T1 is available for Internet and data networking usage.
Depending on the codec, each voice call can be packet compressed to 30 kbps of bandwidth – less than half of the traditional 64 kbps – without any loss in call quality. Up to 24 phone calls can be in progress simultaneously and half of the T1′s bandwidth (768 kbps) still remains available to support Internet access and data networking.
