Dialogic® I-Gate® 4000 Session Bandwidth Optimizer Mobile Backhaul

I-Gate 4000 SBO Backhaul

The Dialogic® I-Gate® 4000 Session Bandwidth Optimizer Mobile Backhaul (I-Gate 4000 SBO MB) is a standalone system that can optimize bandwidth and increase bandwidth capacity significantly in the backhaul segments of both 2G and 3G mobile networks. Because it optimizes Abis and Iub data streams, including both ATM and IP-based Iub streams, the I-Gate 4000 SBO MB can provide a cost-effective and efficient strategy for increasing backhaul capacity, resulting in significantly reduced capital and operation expenses.

The I-Gate 4000 SBO MB can also accept native IP and PCM streams and transmit the combined optimized stream over TDM and/or IP.

Along with Abis and Iub optimization, the I-Gate 4000 SBO MB leverages statistical multiplexing and grooming techniques developed by Dialogic that have been shown in field trials to typically double the capacity of backhaul links while preserving the quality and integrity of the original data traffic through Quality of Service (QoS) protection techniques.
