Dialogic® SS7G21 and SS7G22 Signaling Gateways: Digital Signal Conversion Mode
Dialogic SS7G21 and SS7G22 Signaling Gateways with Digital Signal Converter (DSC) software operate as protocol converters, enabling developers to easily perform protocol conversions between SS7 circuit-related protocols and access-signaling protocols, including ISDN and SIGTRAN M2PA for long-haul configurations.
| Features and Benefits | |
| Provides protocol interworking between any pair of supported telephony protocols for both network protocols (such as SS7 or SS7 over SIGTRAN M2PA) and access protocols (such as DPNSS, ISDN, etc.) | Lets network designers interconnect a variety of "off-the-shelf" network elements that may be running incompatible protocols. Network designers need not request time-consuming and expensive modifications to third-party network equipment |
| A higher level of SS7 building-block integration with ISDN and SIGTRAN | Developers can focus on application development and deployments that address the needs of premium SS7 market segments instead of SS7 integration |
| Housed in telco-grade NEBS-compliant chassis with built-in resiliency for SS7 links and networks that comes as a packaged SS7 building block | Proven and highly-resilient platform , which has been engineered for central office deployments |
| Intelligent call routing capabilities | A signaling gateway can be used as a non-blocking switch and can perform parameter manipulation to support the intelligent call routing capabilities required for value-added services |
| Simple configuration and quick installation | Allows for an easier installation, which does not require development when providing protocol conversion (e.g., between SS7 and ISDN) |
