The IPGate technology offers features that reliably transport legacy Time Division Multiplexing (TDM) and other circuit-based applications over IP/Ethernet or VLAN packet switched networks. Using Circuit Emulation Services over Packet (CESoP) and Structure Agnostic TDM over Packet (SAToP) standards, the IPGate supports a wide variety of legacy analog and digital interfaces at configurable data rates ranging from 50 bps to 52 Mbps. The IPGate Legacy Circuit to IP Gateway lets customers easily and reliably take advantage of converged IP networks to transport legacy circuits.

Specific to the IPGate family is a Gigabit Ethernet backplane and distributed architecture which makes the IPGate a future-proof investment with a virtually unlimited variety of supported

The IPGate unit’s distributed architecture allows any-to-any connectivity between ports and devices enabling a user to create circuit connections over various interface types.
