Description

The Dialogic® DSI SS7LDH4 Network Interface Board offers SS7 network connectivity to service nodes handling low volumes of signaling traffic (for example, 200 calls per second or less), and its half-sized PCI Express form factor helps reduce deployment costs. These characteristics, in addition to the ability to choose a bundle of circuit protocols in capacities suitable for small configurations, can help businesses meet the price points needed for success in a highly competitive segment of the market.

The DSI SS7LDH4 can deliver cost-effective signaling functionality for value-added services, such as call completion, prepaid calling, and call routing applications.

The DSI SS7LDH4 supports the Dialogic® DSI SS7 Stack, allowing API-level compatibility with applications developed for other Dialogic® DSI SS7 Boards, including the Dialogic® DSI SPCI Network Interface Boards. Application development for the SS7LDH4 is accelerated by a comprehensive suite of test utilities, sample code, and user-part programming guides.
