Static Trunking Optimization

IP Telephony Media Gateways for Transparent End-to-End Connections

To complement the software-based ControlSwitch System, Dialogic provides media gateways that interconnect different types of digital media streams to create a transparent end-to-end path for voice, video, and data. Available in a range of functionality and sizes, these gateways also include premier bandwidth and codec optimization that can reduce costs significantly in the access and core portions of the network.

Softswitch-Based Packet Toll/Tandem and Other Services

I‑Gate 4000 Media Gateways can be controlled by the ControlSwitch System using MGCP, H.248/Megaco, or SIGTRAN. Through standards support, the I‑Gate 4000 Media Gateways enable carriers to deploy next-generation VoIP switching solutions for applications such as domestic and international long-distance services, wireline or wireless network tandem switching, Class 4 switch replacement, and PRI trunking. The illustration on this page provides examples of VoIP switching applications.

VoIP Switching Applications

Mobile Network Point of Interconnection

A significant number of calls between mobile phones and PSTN phones require transport through the PSTN long-distance switching and transmission infrastructure. The mobile network operator often has to pay the wireline operator very high fees for long-distance service. By using a static trunking solution that compresses the traffic between the MSC site and a POI site near the local PSTN switch, the mobile operator can achieve significant savings by avoiding the need to pay long-distance fees. See the illustration “Inter-MSC and Point-of-Interconnection” for an example.

Static Trunking in Satellite and Radio Link Applications

The high-compression techniques and voice quality protection mechanisms of I‑Gate 4000 Media Gateways enable a cost-effective static trunking solution for satellite and radio link routes over TDM or IP links. The solution can be deployed either in a single-route point-to-point configuration, or in a point-to-multipoint configuration (supporting multiple bearer links), thus handling traffic to multiple destinations. See the illustration “Satellite Static Trunking” for an example.
