The IPGate-HD32, legacy circuit to IP gateway, reliably transports Time Division Multiplexing (TDM) and other circuit-based applications (such as radio over IP- RoIP) across converged IP networks to deliver the cost, efficiency, and reliability benefits of IP technology migration. Employing Circuit Emulation Services over Packet (CESoP) and Structure Agnostic TDM over Packet (SAToP) standards, the IPGate-HD32 supports a wide variety of legacy analog and digital interfaces at configurable data rates ranging from 50 bps to 34 Mbps.   Using a Gigabit Ethernet backbone and distributed architecture makes the IPGate-HD32 gateway a future proof investment with virtually unlimited variety of supported interfaces.
