Telephony Cards

Serial Synchronous Interface Cards

Whether you use the card to simplify routing and increase security using Sangoma’s WANPIPE® software; you need support for an X.25 link, a datascope, an SNA connection, or a broadcast satellite feed; or you have another unique application — Sangoma’s Synchronous Dual Serial products communicate mission-critical radar control and surveillance data, essential to modern air and sea communications.

This updated card boasts field upgradeable firmware, a choice of PCI or PCI Express interface, and two primary ports that have equal baud rates without the complexity of signaling jumpers.

The A142 and A144 Synchronous Dual Serial Cards are based on the same advanced engineering design as the award-winning AFT Product Line.

Trust the Sangoma® name to deliver optimum data support on standard telecommunications networks.
