Huawei EVDO for RBxxx USB

This example shows how to get HUAWEI E630 Data Card modem working with LMT (Latvian Mobile Telephone UMTS/GPRS networks), or with Amigo (GPRS network) in Latvia. Service in your country might have different requirements and strings, but this is just to give you an outline of what is required.

Hardware

Router Hardware: MikroTik Router with USB port(s) (RB230, any x86 system, RB433UAH, or, RB411U when available with USB)

Router Software: RouterOS V3.x (works in v2.9.x as well). Configuration is changed since V3.23.

USB Modem: HUAWEI E630 Data Card

The USB Modem is recognized in RouterOS as an USB device and listed under the USB resources:

[admin@RB433UAH] > system resource usb print # DEVICE VENDOR NAME SPEED 0 2:1 RB400 EHCI 480 Mbps 1 2:2 ST ST980811AS 480 Mbps 2 1:1 RB400 OHCI 12 Mbps 3 1:4 HUAWEI Technologies HUAWEI Mobile 12 Mbps [admin@RB433UAH] >

Make sure the USB port is listed under the port menu:

[admin@RB433UAH] > port print Flags: I - inactive # NAME CHANNELS USED-BY BAUD-RATE 0 serial0 1 Serial Console auto 1 usb2 2 9600 [admin@RB433UAH] >

Set the baud rate to 9600 for communicating with the modem, in case it's not done already:

[admin@RB433UAH] > port set usb2 baud-rate=9600

Check the modem responses using serial-terminal, like this:

[admin@RB433UAH] > /system serial-terminal usb2 channel=0 [Ctrl-A is the prefix key] ATI Manufacturer: huawei Model: E220 Revision: 11.110.01.03.00 IMEI: 351827013145181 +GCAP: +CGSM,+FCLASS,+DS OK

Router Configuration for PPP

LMT requires, that you specify remote IP address 212.93.97.200 for the ppp connection, therefore we create a new profile:

/ppp profile add name=ppp-LMT remote-address=212.93.97.200

The modem initialization string for HUAWEI is

AT+CGDCONT=1,"IP","internet.lmt.lv"

the number to dial is *99***1# no username and no password. Therefore we create a ppp-client interface as follows:

/interface ppp-client \ add port=usb2 profile=ppp-LMT dial-command=ATDT phone=*99***1# \ modem-init="AT+CGDCONT=1,\"IP\",\"internet.lmt.lv\"" \ add-default-route=yes use-peer-dns=yes name=ppp-lmt

You get a nice interface, jut enable it and go!

[admin@RB433UAH] /interface ppp-client> print Flags: X - disabled, R - running 0 X name="ppp-lmt" max-mtu=1500 max-mru=1500 mrru=disabled port=usb2 command-channel=0 data-channel=0 info-channel=0 user="" password="" profile=ppp-LMT phone="*99***1#" dial-command="ATDT" modem-init="AT+CGDCONT=1,"IP","internet.lmt.lv"" null-modem=no dial-on-demand=no add-default-route=yes use-peer-dns=yes allow=pap,chap,mschap1,mschap2

The interface monitor will say status:

[admin@RB433UAH] /interface ppp-client> monitor ppp-lmt status: "connected" uptime: 47s idle-time: 47s mtu: 1500 mru: 1500 -- [Q quit|D dump|C-z pause]

There is IP address assigned and default route installed:

[admin@RB433UAH] > ip address print Flags: X - disabled, I - invalid, D - dynamic # ADDRESS NETWORK BROADCAST INTERFACE 0 10.5.8.157/24 10.5.8.0 10.5.8.255 ether1 1 D 10.35.151.128/32 212.93.97.200 0.0.0.0 ppp-lmt [admin@RB433UAH] > ip route print Flags: X - disabled, A - active, D - dynamic, C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme, B - blackhole, U - unreachable, P - prohibit # DST-ADDRESS PREF-SRC G GATEWAY DISTANCE INTERFACE 0 ADS 0.0.0.0/0 r 212.93.97.200 1 ppp-lmt 1 A S 10.5.0.0/16 r 10.5.8.1 1 ether1 2 ADC 10.5.8.0/24 10.5.8.157 0 ether1 3 ADC 212.93.97.200/32 10.35.151.128 0 ppp-lmt [admin@RB433UAH] >

We were achieving ~770kbps download speeds when the HUAWEI cards indicator was blue (UMTS), and ~122kbps when green (GPRS). Better results are if you turn off compression in the ppp profile.

You can get more status information about the modem and network, if you disable the ppp-client and run the "info" command:

[admin@RB433UAH] /interface ppp-client> info ppp-lmt pin-status: "READY" manufacturer: "huawei" model: "E220" revision: "11.110.01.03.00" serial-number: "351827013145181" activity-status: "call in progress" functionality-status: "full" gprs-mode: "B - EDGE" current-operator: "LV LMT GSM, LV L" signal-level: "-59 dBm" [admin@RB433UAH] /interface ppp-client>

You can scan for available GSM networks using the "scan" command:

[admin@RB433UAH] /interface ppp-client> scan ppp-lmt Flags: A - active OPERATOR SIGNAL-STRENGH NUMBER A LV LMT GSM, LV L -57 dBm 24701 LV TELE2 24702 BITE LV 24705 -- [Q quit|D dump|C-z pause]
