  • ZTE Bavo H110 Router Clarification

    I have to demonstrate on the functions of the
    home gateway with the home Telco. I will like that you
    open to the H11x user manual and explain detailly with
    examples the following with applications.
    - Remote Access Control page 85 of the H11x manual.
    - Port Trigger
    - Port Forwarding page 81
    - Adding New Connection page 96
    - Media Configuration page 112
    - Route Select Configuration page 118
    - Service Configuration page 121
    Just a quick overview of the functionality:
    1. Remote Access Control is if you want a remote user in the Internet to be able to control the H110. Here you enter their remote ip address and what remote service you would like to give them permission to use. So for example if you wanted us to be able to control you H110 you would enter our ip address there.
    2. A port trigger basically allows the PC in the LAN to open a port (the trigger port) that the Internet application server can access the application in the PC through. This prevents you having to open more ports than you need for security reasons. For example you can set up ICQ port trigger to a UDP port 4000 (thereby enabling this port in the SPI firewall) then setup a rule that when that port is triggered to open port TCP ports 20,000 to 20,059.
    3. Port forwarding is actually quite important and we use this a lot (eg for VNC). Remember the H110 is a NAT device (Network Address Translation). To the outside world you have only one ip address the public ip address given to you by your cellular carrier through your EVDO modem. Internally there's a DHCP server that generates multiple ip addresses for each PC. If you need to access a PC remotely using VNC (eg you would need to do port forwarding of port 5900 to the destination ip address of the PC you want to view remotely. Say for example if your public ip address is and the ip address of the PC you want to remotely view is
    4. Adding a new connection has to do with configuration of a VPN (Virtual Private Network) tunnel. We haven't tested the VPN endpoint functionality and most people seldom use this feature. Most people have other hardware to setup VPN and just require VPN pass-through
    5. Media configuration has to do with SIP protocol for both voice media of fax media. These configurations need to come from your VOIP provider or Fax over email host. The following audio codecs are supported G711U (U-law), G711A (A-law), G729, RFc2833. Note that the Using G711 for VoIP will give the best voice quality since it uses no compression and it is the same codec used by the PSTN network and ISDN lines. It also has the lowest latency because there is no need for compression, which requires processing horse power. The problem however is that it requires more bandwidth then other codecs, up to ~90 Kbps. This is might be a problem especially for EVDO Rev0 networks since this is the typical reverse link (upload) datarate. For EVDO RevA your fine. A nice thing about the G711 is that it's supported by the most VoIP providers.
    6. Route selection configuration is for PBX configuration and allows you to specify what a call uses VOIP or PSTN. A nice example for U.S users is where you would use PSTN for local calls since in the U.S these are free (or flat rate) and use VOIP for nationwide long distance and international calls. Depending on your particular billing model or preference you would want to change your route selection accordingly.
    7. Service configuration is pretty standard for VOIP systems and allows you to configure what services are available in what VOIP line. An example would be where you would forward a business line to a cellphone based on different conditions e.g if your phone line is busy to forward or to forward unconditionally.
