Dialogic DSI SS7MDL4 Network Interface Board
Low Density Signaling for Effective Value-Added Services
Get a Quote!
The Dialogic DSI SS7MDL4 Network Interface Board offers multiple levels of signaling link density for SS7 and ATM networks in rack-mount servers with low-profile or full-height PCI Express peripheral slots. Flexible capacity licensing enables message processing from 16 to 124 low-speed links or 2 or 4 high-speed MTP or ATM links.
The DSI SS7MDL4 supports the Dialogic Distributed Signaling Interface (DSI) SS7 Protocol Stack, allowing API-level compatibility with applications developed for other DSI network interface boards including Dialogic DSI SS7HD and DSI SPCI Network Interface Boards. Application development for the DSI SS7MDL4 is accelerated by a comprehensive suite of test utilities, sample code, and user-part programming guides.
The DSI SS7MDL4 delivers the high-capacity message-signaling-units-per-second performance required for demanding value-added services such as messaging, call completion/prepaid calling, roaming, and intelligent network applications.
The DSI SS7MDL4 can be licensed and deployed with a number of different link capacities and network protocols to allow scaled pricing to match the levels of throughput required. See the table of order codes at the end of this datasheet for a list of options.
Easy Migration for Existing Signaling Applications
Existing signaling-only applications using Dialogic DSI APIs or the Dialogic Global Call API for SS7 and currently deployed with DSI SS7HDP or DSI SPCI Network Interface Boards can be executed on systems configured with the DSI SS7MDL4 without programming changes in the service logic. Applications using the CT bus functionality of the DSI SS7HD or DSI SPCI Boards will require modification to use the drop-and-insert feature of the DSI SS7MDL4. Alternatively, other Dialogic products that support the CT bus or combined signaling and media may be used. Contact your Dialogic sales representative for information on other Dialogic products and capabilities.
