TDM Pseudowire Access Gateway

RAD IPmux-4L

A high-performance gateway extending TDM-based services over Packet Switched Networks (PSN). Combining TDM pseudowire functionality with Ethernet access, the IPmux-4L ensures robust, low-latency delivery of legacy E1 circuits across modern IP/MPLS infrastructures.

Pseudowire Performance & Standards

Architecture	ASIC-based forwarding for minimal processing delay and wire-speed performance
PSN Protocols	Full support for TDMoIP, CESoPSN, SAToP, and HDLCoPSN over IP and MPLS
Jitter Compensation	Advanced jitter buffer compensates for Packet Delay Variation (PDV) of up to 200 msec
Addressing Scheme	Supports IP/UDP and MPLS encapsulation for transparent TDM-over-Packet transport
Flow Classification	Uses IANA-registered UDP port numbers to simplify traffic classification through routers
Throughput Optimization	Configurable packet sizes to balance network throughput and processing delay

Key Advantages

ASIC-Driven Reliability

The hardware-based architecture provides a robust, high-performance solution that handles TDM conversion with negligible latency—ideal for delay-sensitive applications.

Dual Functionality

Operates simultaneously as a TDM pseudowire gateway and an Ethernet-based access device, maximizing the utility of a single network termination point.

Network Versatility

Easily integrates into existing PSNs by converting E1 streams into standard-compliant packets that are easily routed and managed by existing L2/L3 infrastructure.

Scale Your Legacy Services over Ethernet
