IPmux-2L, IPmux-16L

TDM Pseudowire Access Gateways

The IPmux-2L and IPmux-16L are cost-effective TDM pseudowire access gateways, extending TDM, HDLC and LAN traffic over dark fiber, IP, MPLS, or Ethernet.




Ideal for delivery legacy PBX and leased lines over packet

Using TDM pseudowire technology, the IPmux-1E delivers ISDN BRI, echo-cancelled E1/T1 or FXS/FXO/E&M services over packet transport, in addition to enabling transparent LAN bridging. It supports carriers in their migration to next-generation networks by allowing them to continue generating revenues from their ongoing legacy services over PSNs. The ease of installation and support for legacy and next-generation Ethernet and IP-based services make it ideal for small and medium-size enterprises (SMEs).
