Overview:
The Dialogic I-Gate 4000 Mobile Backhaul Session Bandwidth Optimizers (I-Gate 4000 MB SBO and I-Gate 4000 MBX SBO) are standalone systems that can optimize bandwidth and increase bandwidth capacity significantly in the backhaul segments of both 2G and 3G mobile networks. Because they optimize Abis and Iub data streams, including both ATM and IP-based Iub streams, the I-Gate 4000 MB or MBX SBO can provide a cost-effective and efficient strategy for increasing backhaul capacity, translating to significantly reduced capital and operation expenses. The I-Gate 4000 MB and MBX SBOs both offer several configurations and interface types, each of which has the same technical features.
I-Gate 4000 MB and MBX SBOs can also accept native IP and VoIP streams and transmit the combined optimized stream over TDM and/or IP. Along with Abis and Iub optimization, the I-Gate 4000 MB and MBX SBOs leverage 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.
Efficient Mobile Backhaul Optimization
Both the I-Gate 4000 SBO MB and I-Gate 4000 SBO MBX can optimize bandwidth in the backhaul segments of both 2G (Abis) and 3G (Iub) streams (ATM and IP-based). In addition to Abis and Iub optimization, either one can also be used to simultaneously take in VoIP and IP streams, to optimize these streams, and to transmit the optimized stream over Ethernet and/or TDM. See Figure 1 for an example of a sample configuration. Because units are placed within the current physical backhaul segment, optimizing with an I-Gate 4000 MB or MBX SBO is not as disruptive or costly as other alternatives for increasing bandwidth capacity, such as adding expensive leased lines, deploying fiber, adding microwave spectrum, or moving to Ethernet ring. I-Gate 4000 MB and MBX SBOs can also be used in addition to other options for increasing bandwidth capacity, and can coexist with such other options.

Key Performance Indicators
The I-Gate 4000 MB and MBX SBOs monitor and maintain Key Performance Indicators (KPI) by which mobile backhaul infrastructure performance is measured. These include delay, jitter, bit error rate, and availability. Adherence to prescribed KPIs is considered critical to maintaining high subscriber Quality of Experience (QoE) and to meeting Service Level Agreements (SLAs) for voice and data services.
Application Topologies
Both the I-Gate 4000 SBO MB and the I-Gate 4000 SBO MBX support a wide range of deployment strategies, including these topologies:
- Point to Point (PTP)
- Point to Multi-Point (PTMP)
- Drop and Continue
- Ring
- Data Offload
Deployments may consist of the I-Gate 4000 SBO MB, the I-Gate 4000 SBO MBX or a mixture of both depending on needs.
Dialogic XMS Management System
The Dialogic xMS Management System provides the network operator with an enhanced Fault, Configuration, Performance and Security management tool to manage a network of I-Gate 4000 MB and/or MBX SBO terminals.
The xMS provides an easy to use web-based interface with a logical step-by-step approach to provisioning and event handling. The xMS provides a rich set of reports for the operator, depicting the traffic and operational information of I-Gate 4000 MB and/or MBX SBO terminals. It also provides alarm and event handling mechanisms to help the operator troubleshoot the network and isolate faults. Runtime configuration provides the ability to change the working parameters of I-Gate 4000 MB and/or MBX SBOs without the need to reset the terminal and disrupt traffic. Figure 2 shows a snapshot of the configuration and bandwidth usage.
