Signaling Boards

Two families of Dialogic® SS7 boards are available to enable affordable, high-performance, signaling applications.


Dialogic® Distributed Signaling Interface (DSI) boards are designed for distributed execution of SS7 message processing across board processors, application host CPUs, or separate signaling servers. The products in this family are:

- SS7MDL4 - High-density, PCI Express, low-profile board.  Offers multiple levels of signaling link density for SS7 and ATM networks in rack-mount servers with low-profile PCIe peripheral slots. Flexible capacity licensing for signaling or HiZ monitoring of up to 124 low-speed links or up to 4 high-speed MTP or ATM links.

SS7LDH4 - Low-density, PCI Express, half-length board.  Board and protocol license bundles available to manage up to 4096 ISUP circuits and up to 16 low-speed links.

- SPCI - Low-density, PCI, full size board, offers up to 4 Channelized links over E1/T1 or V11 ports and monitoring.
