    However, to take advantage of the data network, it is neither cost effective, nor necessary to hastily replace all the TDM based equipment with new packet based equipment. The H0FL-ETHMUX V16 can be used to emulate transparent E1 channels over an Ethernet with adequate QoS, so that most of the existing E1based applications can be readily setup over Ethernet LANs and WANs.

  • Page 6: Applications

    POE power supply supported by power module with 220V AC input and 55V DC output. 1.2 Applications H0FL-ETHMUX V16 is used to setup 1~16 transparent E1/T1 channels over LAN or IP networks, as depicted in Fig. 1.2-1. - 2 - TDMUX-16 User Manual V1.2...
  • Page 7 E1 channels get higher priority over computer data for maximum QoS. The most widely used application of H0FL-ETHMUX V16 is to set up point to point wireless E1/T1 links using low cost wireless LAN bridges. H0FL-ETHMUX V16 can work with most LAN bridges on the market.

  • Page 8: Timing Modes

    For example, setting the H0FL-ETHMUX V16 unit connected with the clock master (such as local exchange) to loop back mode, and the other unit connected with the clock slave (such as PBX or remote module) to adaptive mode, is probably better than setting both to adaptive modes.
