IPmux-11 & IPmux-1E - TDM Pseudo-Wire Gateways


Product Summary

IPmux-11 TDM pseudo-wire gateway and IPmux-1E pseudo-wire gateway are TDMoIP gateways designed to meet the needs of small and medium sized enterprise sites. Both gateways offer Ethernet-based access as well as extension of TDM-based services over packet-switched networks. The IPmux-1E pseudo-wire gateway also provides ISDN BRI and FXS/FXO/E&M services. The units’ ultra-low delay time meets Quality of Service requirements. 


  • Eliminates point-to-point E1/T1 leased lines 
  • Low latency meets QoS requirements 
  • Supports legacy PBX, including proprietary features and signaling 
  • Leased lines, cellular backhaul, and international toll bypass can be run over the PSN 

Quick Specs 

  • Transmit TDM-based services over packet switched networks (Ethernet, IP or MPLS)
  • IPmux-11 provides single E1 or T1 TDM user port
  • IPmux-1E provides analog, ISDN BRI and E1/T1 user ports with echo cancellation
  • Fiber and copper Ethernet uplink interfaces
  • Wire-speed bridging of user LAN traffic to the packet-switched network
  • Transparent to all signaling protocols
  • QoS support 
  • Centralized SNMP-based management 

Further Product Information 

Compact TDMoIP customer premises gateways

IPmux-11 TDM pseudo-wire gateways and IPmux-1E 11 TDM pseudo-wire gateway are designed to meet the requirements of small customer premises sites. They reduce operating expenses by delivering virtually all TDM, data and LAN services over IP/Ethernet/MPLS networks, while ensuring strict priority for the TDMoIP traffic over the network link. End users continue to receive all familiar services, while carriers and service providers maintain revenues from legacy services. The compact size, ease of installation and support for multiple legacy and next generation Ethernet and IP-based services make these devices ideal for small and medium-sized enterprises (SMEs). 

Ethernet access

IPmux-11 TDM pseudo-wire gateway and IPmux-1E TDM pseudo-wire gateway answer the growing need of business customers for transparent LAN services (TLS) such as LAN-to-LAN interconnection and Ethernet connectivity to service providers. Enhanced features such as user LAN port rate limiting enable adapting the total bandwidth transmitted to the limitation of the transport media. VLAN stacking allows the encapsulation of multiple locally used VLANs over a single network media for efficient network engineering.

TDM circuit extension

Both TDMoIP gateways can provide any user device with standard E1/T1 interface circuit extension over PSN. The IPmux-1E also offers connectivity for four ISDN S0 channels or four analog voice channels, with optional near-end echo cancellation (up to a full E1/T1) for cases where a large end-to-end delay causes echos, such as in satellite applications. Both devices support alarm detection and insertion along with error statistics, SES/UAS statistics, LOS/AIS physical layer alarms, and remote/local loop tests. The devices support standard E1/T1 alarms from end-to-end.


IPmux-11 TDM pseudo-wire gateway is equipped with the following interfaces: 

  • One standard E1/T1 user port 
  • Two Ethernet ports with optional 10/100BaseT or 100BaseFX interface serve as network uplinks or user ports 
  • One Ethernet user port with 10/100BaseT interface for LAN connectivity 
  • Optional external clock port (E1/T1 rate) option 

IPmux-1E TDM pseudo-wire gateway is equipped with the following interfaces: 

  • TDM user port options:   
    – Single standard E1/T1 port with echo canceller
    – Four analog (FXS/FXO/E&M) ports with optional echo canceller  
    – Four ISDN S0 ports 
  • One Ethernet uplink with 10/100BaseT or 100BaseFX interface 
  • Optional Ethernet user port with 10/100BaseT interface for LAN connectivity 
  • Optional external clock port (E1/T1 rate)
