IPmux-4 - E1/T1 Emulator for IP Networks IPmux provides a compact, minimal configuration solution for virtual E1/T1 point-to-point applications, transporting E1/T1 services over IP and Ethernet based networks. IPmux takes data streams from up to four E1/T1 ports and converts them to packets for transmission over the network. The addressing scheme of these frames is IP. These frames are transmitted via the IPmux 10/100BaseT port to the network. A second IPmux at the remote location converts the IP packets back to E1/T1 traffic. The overall effect of the IPmux is to allow transparent E1/T1 connectivity over the new generation of switch based packet networks, both in the carrier and the corporate environments.
