IPmux-24
TDM Pseudowire Access Gateway
• Comprehensive support for pseudowire/circuit emulation standards including TDMoIP,
CESoPSN, SAToP, CESoETH and HDLCoPSN
• Industry-leading adaptive clock recovery mechanism suitable for cellular backhaul over
packet-based networks
• Carrier-class/environmentally hardened device
• Extensive OAM and performance monitoring capabilities
• Three auto-detecting Gigabit or Fast Ethernet SFP- or UTP-based ports, and one, two
