OpenSS7 Corporation has historically provided hardware cards for use with its software stacks directly to clients. We no longer stock inventory of hardware cards for resale. However, for PCI/PCIe busses, we highly recommend the 4-port E1/T1 CP400 cards available from Allo.

These cards follow the original Jim Dixon Zapata Telephony design, are open hardware, and sport a recent Dallas framer chip.

OpenSS7 has historically developed drivers for a number of E1/T1/J1 cards from various vendors, both in the PCI/PCIe form factors as well as CompactPCI and mezannine cards with varous framer chips. If you need driver development for specific hardware; contact us at info@openss7.com, or see our Contact page.
