3 MP01 Administrator Manual This document describes detailed information for the MP01, and it will guide you through the installation for setting up telephony system and providing Internet access with MP01. 1. Introduction The MP01 is a WiFi mesh VoIP ATA (analog terminal adapter) operating in the license-exempt 2.4GHz ISM band. The MP01 is the first WiFi mesh ATA in the market, using a wireless mesh network as backhaul to interconnect phones and host LAN/WAN access to computers connected to its Ethernet port. MP01 WiFi mesh ATA helps you to build the wireless VoIP communication system with open hardware design and open source firmware. It provides affordable voice and data services for people. 1.1 Mesh networking Mesh networking is a type of networking wherein each node in the network may act as an independent router, regardless of whether it is connected to another network or not. It allows for continuous connections and reconfiguration around EURNHQRUEORFNHGSDWKVE\³KRSSLQJ´IURPQRGHWR node until the destination is reached. A mesh network whose nodes are all connected to each other is a fully connected network. Mesh networks differ from other networks. Mesh networks can be seen as one type of ad hoc network. Mesh networks are self-healing: the network can still operate when one node breaks down or a connection goes bad. As a result, the network may typically be very reliable, as there is often more than one path between a source and a destination in the network. 1.2 The client-MP01 MP01 is an 802.11b/g mesh router with a single FXS port and one 10/100Mbit Ethernet port. The Mesh Potato hardware and software is open. The power, Ethernet and FXS ports are robust in order to deal with developing-world conditions like static electricity, lightning, bad power and accidental abuse. It comes in a weatherproof box for outdoor mounting and costs about the same as any other Wi-Fi router. An analogue phone connects to the MP01 via the FXS port. FXS (Foreign eXchange Station) is a telephone interface that supplies power, dial tone and generates ringing voltage. The mesh network can be augmented via backbone links and connected to the rest of the world using VoIP trunks.
4 1.3 Server Only one computer is required to provide the services for the Telco system. This computer, called the VT Server, could be anything from a standard laptop to a high-end server for better redundancy. The services on this computer are made up of several elements including Afrimesh, A2Billing and A3Glue. The server part consists of several software elements. Afrimesh Afrimesh provides a simple management dashboard helping network operators create and sustain resilient communications networks with a minimum of fuss. Featuring z Powerful mesh network routing with B.A.T.M.A.N. z Dynamic GIS visualization of your mesh on OpenStreetMap maps. z Plan your network using the terrain elevation map. z Visualize live health&traffic information for any mesh node. z Keep inventory of your network devices. z Monitor the health&usage of your Internet gateway. z Monitor live network accounting information from pmacct. z View network status & log messages in realtime. z Customer management interface featuring FreeRADIUS support. z Customer authentication featuring coova-chilli support. z Online help and live chat support. z Intelligent configuration assistance. z Build and manage mesh networks even without an Internet connection. A2Billing A2Billing combined with Asterisk is a full featured telecom platform and softswitch providing converged services, with self contained billing (pre or post-paid), reporting and statistics for IP and TDM based voice networks and can be configured to supply a wide range of services, rate calls, prepare and send out invoices, as well as accept payments via a number of payment service providers. The A2Billing solution comprises of the following components: z Server: The computer to run the system. z Line Interface Cards: The ATCOM telephony cards hardware (optional) to connect to the TDM network (PRI, BRI, Analogue) z Linux: The base operating system z Asterisk: The telephony engine z Apache: The web server z MySQL/Postgresql: The back end database z A2Billing: The Billing engine handling Authentication, Authorization and
5 Accounting. A3Glue This is the glue, making Afrimesh, A2billing and the Mesh network work together. It gathers data from the network, provisioning the MP01 and make sure everything runs smoothly. 2. Scenarios and Installation Guide 2.1 Scenarios Stand-alone installation MP01s can be deployed from two units and you can make calls between them. You can then add more units to the network one at a time. You will be able to make calls and can have a closed network between the units. For the installation guide, please refer to ATCOM MP01 Quick Start Guide V1.0.pdf. Telephony installation Deploy the MP01 for telephony and add a SIP Provider or PSTN connection to the A2Billing server. This will allow for free calls between the units and cheaper international calls. Internet Installations Using the MP01s to provide Internet connection. The Internet traffic goes out through a common gateway. The community needs to pay for an Internet connection through an Internet Service Provider and share the costs between its members. Combined Internet and Telephony installation Deploy MP01s and use it both for Internet and telephony. You connect an Internet gateway for shared broadband for the users and telephony connection to call international. 2.2 Installation Guide The network topology is shown as below. We are going to deploy a system like this.
6 In this network topology, all the MP01 is an extension and act as mesh node also. And VT Server is installed Afrimesh and act as a visualization server. We use IP08 as Asterisk server, and all the MP01 are registered to IP08. The feature of this system is: z Every MP01 has a WiFi IP and a phone number, the phone number is the same as the last digit of the WiFi IP, for example, the Mesh node A has a WiFi IP 10.130.1.50 and a phone number 50. z (YHU\03FDQEHDUHSO\IRURWKHU03,W PHDQVHYHQ03%FDQ¶Wreach MP01 C directly, it can be still possible to reach MP01 C via MP01 A. z MP01 can not only make internal calls, but international calls through IP08. z It is very convenient to manage the mesh network on the VT Server. z Any computer on the network should be able to talk to any other computer on the network. For example a computer connected to mesh node A should be able to download content from a web server connected to mesh node C. z Computers connected to the MP01 by Ethernet port can access the Internet. The following steps will show you the configurations. 2.2.1 Afrimesh Server Setup This installation assumes that you have installed Ubuntu 10.04 LTS on your server and have since updated and upgraded your packages. It also assumes you have a wireless driver that works in ad-hoc mode. And all the MP01s are running version rv233. This has been testing on the computer with the following hardware: CPU: Pentium Dual-Core E5200 2.5GHz Memory: 2GB HDD: 40GB Wireless Adapter: DrayTek Vigor N61 802.11n 1) Add the Afrimesh repository

For the configuration guide, please refer to ATCOM MP01 Quick Start Guide V1.0.pdf. 1) Get the Afrimesh packages for the MP01 on Afrimesh Server wget http://download.villagetelco.org/vte/afrimesh/954/netcat_0.7.1-1_mips.ipk wget http://download.villagetelco.org/vte/afrimesh/954/villagetelco-device_1.0pre-r954-1_mips.ipk
8 If you haven't already set the password on the MP01, do that now by telneting to 192.168.1.20 and issuing the µpasswd¶ command. This will enable ssh and you will be able to continue with the following. 2) Copy the packages to the MP01. scp *ipk root@192.168.1.20:/root 3) Login into the MP01 ssh root@192.168.1.20 4) Install and configure the packages on MP01 (Answer µY¶ when asked to replace /etc/config/afrimesh) opkg install netcat_0.7.1-1_mips.ipk opkg install villagetelco-device_1.0pre-r954-1_mips.ipk /etc/init.d/provision enable chmod -R a+rw /etc/config uci set batmand.general.routing_class=1 uci set afrimesh.settings.root=10.130.1.1 uci set batmand.general.visualisation_srv=10.130.1.1 uci set system.@system[0].log_ip=10.130.1.1 uci commit reboot 5) Configure DNS for MP01 Edit /etc/resolv.conf to reflect the following: nameserver 141.1.1.1 2.2.3 Start up the Afrimesh Dashboard You may be able to make this all work with the Network Manager but I ran into problems and disabled it. So, first kill the network-manager and stop any versions of batmand that might be running. You may wish to paste the below into a script for convenience. The commands should be run as root. stop network-manager killall NetworkManager killall batmand Then start your wireless interface. Replace wlan0 if necessary with whatever your wireless device. ifconfig wlan0 down iwconfig wlan0 mode ad-hoc ifconfig wlan0 up ifconfig wlan0 10.130.1.1/24 iwconfig wlan0 essid potato iwconfig wlan0 channel 1 iwconfig wlan0 ap 01:CA:FF:EE:BA:BE Assuming your wired Ethernet port is connected, you can set up that connectivity as well. If your Ethernet port is not eth0, adjust as appropriate. iptables --flush iptables --table nat --flush
9 iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE iptables --append FORWARD --in-interface wlan0 -j ACCEPT echo 1 > /proc/sys/net/ipv4/ip_forward Now start the visualisation server. Initially, it is worth doing this in a separate terminal window so that you can monitor the server. Substitute your wireless device if not wlan0. /usr/local/sbin/vis-i386-lucid -d1 -j wlan0 Finally start the batman server. Once again, substitute your wireless device if not wlan0. batmand -d1 -s 10.130.1.1 -g 100mbit ±a 192.168.1.0/24 wlan0 You're now ready to use Afrimesh. Launch Firefox and point your browser at http://localhost/afrimesh, you will see the Afrimesh page as below: Note: Before plugging in any MP01s, don't forget to go to the settings page and set the longitude and latitude for your location. Now you can plug in your MP01 and wait for the bouncing blue ball to appear and the MP01's phone to ring. If you want to clear Afrimesh's database and start again, execute the following: redis-cli flushdb After finishing these, you should be able to manage the mesh network on Afrimesh Dashboard. 2.2.4 Configure the MP01 to make international calls Before configuring the MP01, make sure that you can use IP phone which is registered to the IP08 to make international calls. Assume that you have assigned a SIP account 6015 for MP01. 1) On MP01, edit /etc/asterisk/sip.conf and add some lines as below:
10 [general] register=6015:6015@192.168.1.100 [6015] host=192.168.1.100 secret=6015 username=6015 insecure=very type=friend disallow=all allow=gsm,ulaw,alaw dtmfmode=rfc2833 qualify=yes canreinvite=no nat=yes context=default 2) On MP01, edit /etc/asterisk/extension.conf and add some lines as below: [default] exten => _9.,1,Dial(SIP/6015/${EXTEN:1}) 3) Assume that the outgoing calling rules on IP08 is µ88+phone number¶, then you can use MP01 to make international calls by dialing µ988+phone number¶. 2.2.5 Configure the MP01 to let the computers connected to it by Ethernet port can access the Internet 1) Paste the below into a script named meshclientgw.sh and save it to /bin on MP01. #!/bin/sh # This script has been tested with the ash shell from BusyBox. # Written by Elektra OLD_WIFI0_IP=`uci show network.wifi0.ipaddr | cut -d = -f 2` if [ -z $OLD_WIFI0_IP ] then echo "You need to set a IP address for the wifi0 interface before running this script." exit 1 fi /etc/init.d/batmand /etc/rc.d/S90batmand OCTET_A=`uci show network.wifi0.ipaddr | cut -d = -f2 | cut -d . -f1`

Network => Switch You can set up VLAN settings in this menu. This is yet another option for advanced users. Since the MP01 doesn't have multiple Ethernet ports, this menu is of very limited use.
35 Switch Network => DHCP You need to install the dnsmasq package before using it. You can configure the DHCP options such as assigned range, lease time and so on. DHCP Interface: The device to assign IP addresses
36 Start: The first IP address it will assign Limit: The last IP address it will assign Leasetime: The amount of time a network user will be allowed to connect to the MP01 with their current dynamic IP address. Network => Hostnames You can add hostname entrys here. Hostnames Network => Static Routes A static route is a pre-determined pathway that network information must travel to reach a specific host or network. Static Routes Interface: Select the appropriate interface. Target: Target network where you want to assign a static route Netmask: This determines which portion of a target IP address is the network portion, and which portion is the host portion. Gateway: It is the IP address that allows for contact between the MP01 and the remote network or host.
37 4. Troubleshooting 4.1 What to do if you can¶t connect to the MP anymore - using the Fallback-IP This can easily happen if you are messing around with the IP settings of the MP. Luckily the MP has a additional IP subnet at the Ethernet port that can not be changed or disabled from a web interface. On your PC configure the Ethernet port to use 172.31.255.253/30 (netmask 255.255.255.252). You can add multiple IP addresses to each interface, so you don't have to reconfigure it if you need other addresses as well. After finishing the configuration you should be able to access the MP01 using IP 172.31.255.254. 4.2 My MP01 can¶t make calls You have set up you MP01 IPs but can't make calls. Here are some basic tests: 1. Can you hear dial tone in a phone connected to the MP? If not please reboot it and try again. Some of the modules have come loose while shipping. 2. Check you mesh network. Telnet/ssh into your MP and: batmand -cbd1 You should see the IP of the other MP(s) on your mesh. If you see no IPs then check your WiFi settings are identical except for the IP. These can be checked in /etc/config/wireless or via the GUI. Also compare "iwconfig ath0" on both MPs and "ifconfig ath0". 3. Try pinging one MP from the other. 4. On each MP, dial 4001. This performs an echo test. Can you hear your own voice coming back to you? 5. Start an Asterisk CLI and see what happens when you dial an IP: root@OpenWrt:~# asterisk -r OpenWrt*CLI> set verbose 3 Note: The 'set verbose' command is deprecated, please use 'core set verbose' instead. Now dial the IP of another MP. You should see something like: -- event_offhook -- AST_STATE_DOWN: -- start mp_new -- event_dtmf 1 -- event_dtmf 4 -- event_dtmf 2 -- event_digit_timer -- extension exists, starting PBX 142 -- Executing [142@default:1] Dial("MP/1", "SIP/4000@10.130.1.142") in new stack
38 -- Called 4000@10.130.1.142 -- event_onhook -- default: hangup sound_on = 1 == Spawn extension (default, 142, 1) exited non-zero on 'MP/1' -- start mp_hangup 4.3 Choppy sound This is most likely caused by a poor wireless link. Check that you have line of sight to other MP01. It is also possible to install another MP01 on a nearby building or tower to relay the signals. 4.4 The MP01 is flashed with AP51 The AP51 flash tool re-arranges the disk lay-out. If the MP01 has been updated with the AP51, you CAN NOT upgrade it remotely through wireless. Then you need to do a MP01 Disaster Recovery BEFORE deploying it in the field to be able to remotely upgrade it in the future.
