VOICE OVER ATM TECHNOLOGY

Asynchronous Transfer Mode, or ATM, is a multiservice, high speed, scalable technology. It is a dominant switching fabric in carrier backbones, supporting services with different transfer characteristics. ATM simultaneously transports voice, data, graphics and video at very high speeds.

Large enterprises are increasingly connecting headquarters and main offices to the wide area network via broadband links such as ATM to accommodate their vast amounts of voice and data transmissions, such as heavy graphics, payroll information and voice and video conferencing.

Alliance Datacom has new and refurbished Voice Over ATM equipment. Let our Network Engineers help your company design and build a quality IP Network. Contact our team today.

The two extremes for designing a VoFR network are:

1. A full mesh of voice and data PVCs to minimize the number of network transit hops and maximize the ability to establish different QoS. A network designed in this fashion minimizes delay and improves voice quality, but represents the highest network cost.
2. Most Frame Relay providers charge based on the number of PVCs used. To reduce costs, both data and voice segments can be configured to use the same PVC, thereby reducing the number of PVCs required. In this design, the central site switch re-routes voice calls. This design has the potential of creating a transit hop when voice needs to go from one remote to another remote office. However, it avoids the compression and decompression that occurs when using a tandem PBX.
