Dialogic® Vision™ VS Signaling Server

Dialogic® Vision™ VS Signaling Server photo

The Dialogic® Vision™ VS Signaling Server provides consolidated SS7 signaling capabilities for the Dialogic® Vision™ VG Media Gateway, allowing service providers to take advantage of the cost savings of using inter-machine trunks (ISUP bearer trunks) vs. the generally more costly ISDN trunks. The Vision VS Signaling Server abstracts the complexities of SS7 signaling, eliminating the need for developers and service providers to become experts in SS7 signaling.

Based on NEBS-compliant server hardware, the Vision VS Signaling Server is ready for in-network installation. Two servers may be operated in a redundant, fault-tolerant configuration, sharing a single pointcode and providing node-level redundancy. A DC power option, plus alerts and alarms, further enables the Vision VS Signaling Server to remain up and running.

The Vision VS Signaling Server supports from 4 to 32 ISUP low-speed signaling links (DS0s), or 4 high-speed links (DS1s), over software-selectable T1/E1 trunks. A single Vision VS Signaling Server, or redundant pair, is capable of supporting up to 20 Vision VG Media Gateways, or up to 4,800 ports.

Leveraging years of Dialogic expertise in SS7 signaling, the Vision VS Signaling Server offers proven performance and network interoperability, allowing service providers to interface to virtually any PSTN worldwide.
