Modem Emulation

Sunday, 02 March 2014 23:26

MODEM EMULATION WITH INTELIMAX

Description

Modem emulation assists in the transition from Circuit Switched Data (CSD) to Packet Switched Data/IP (PSD). If the control center management system supports IP but the field devices only support dialing back to the control center using CSD, then you can use the Intelimax to emulate the CSD modem interface. The Intelimax can also be configured to act as an IP stack server for incoming connections if necessary.

Dialing Process

From the perspective of the field device it will dial out a CSD data call like it always has, except the Intelimax will instead establish an IP stack client connection to the server. For example the field equipment may dial the following string: ‘ATDT0412123456’, then wait for the connection to be established by receiving a ‘CONNECT’ message. The Intelimax can be configured to establish an IP stack client connection to one of several different server IP addresses depending on the number dialed.

Intelimax Configuration

The Intelimax must be configured in IP stack auto server or IP stack manual server mode. This configuration can be made using the Intelimax GUI or via AT commands. If the Intelimax is in IP stack manual mode then it will only connect to the network when it receives the ATDT command via serial and will drop the connection when the call is hung up (+++, ATH). If the Intelimax is in IP stack auto mode (server) then it will act as an IP stack server (and therefore could be addressed remotely) until it receives the dial out commands.

Intelimax AT Command Configuration

The Intelimax modem emulation can be configured using the following AT commands:

To enable modem emulation and add a data number to IP address and port number emulation to the list

  • at$$emul=1,phone_number,IP_address,port_number
  • e.g. at$$emul=1,01044204414,10.0.0.1,5000

To check current emulation list (must have already enabled emulation)

  • at$$emul?

$$EMUL: 1,3
0,01044204412,192.168.101.2,3000
1,01044204411,192.168.101.2,30001
2,01044204414,10.0.0.1,5000
OK

To Enable/Disable Modem Emulation – this must be enabled on the server Intelimax for CONNECT message

  • at$$emul=0,0 – disable
  • at$$emul=0,1 - enable

To delete a rule from the list

  • at$$emul=2,list_number
  • e.g. at$$emul=2,1

OK
at$$emul?
$$EMUL: 1,2
0,01044204412,192.168.101.2,3000
1,01044204414,211.232.22.1,500001
OK

CSD to IP change from CSD call

Tuesday, 03 December 2013 23:14

The Maxon Intelimax modem has the unique in-built feature of being able to change between modes and configure settings remotely over a CSD call. This is especially useful if you have a modem in the field that you need to remotely configure using remote AT commands or the Intelimax GUI but are currently using CSD to talk to this modem. Using these commands lets you change to an IP connection for easy access to the device over an IP connection. This feature is available from firmware versions 0.1.67 onwards.

It is very important to ensure that you can access your modem once this is done which means either using a static IP address (private IP WAN or similar) or a public dynamic IP address such as telstra.extranet the WAN IP of which can be found via SMS.

Dialing Process
Dial out to the modem via a command line terminal session to your data modem using the data number of the SIM card in the Intelimax. The sting will be as follows: ATDT0400123456. Once the ‘CONNECT’ message has been displayed you are connected.
Intelimax Remote Configuration Commands
The following commands can be used to change the settings of the Intelimax:

  • Unlock the CSD programming interface: program.maxon.unlock=admin:admin
  • admin:admin are the default username and password, if you have changed these update this command with the appropriate values in the order username:password.
  • Update the cellular APN: program.maxon.apn=telstra.extranet
  • Update the CPN username, password and authentication: program.maxon.auth=userid:password:chap/pap/none
  • Change the mode of the modem: program.maxon.mode=1


Where:
1- IP Stack Auto mode –auto connect IP
2- IP Stack Manual mode –manual connect IP
3- Serial modem mode –for CSD or when end device controls connection

Apply all the settings and reboot: program.maxon.lock
Once the commands have been received by the modem it will display ‘Modem will reboot now’ and the call will be dropped as the modem reboots:
Once the modem reboots (approximately 2 minutes) if a public dynamic IP address has been used it can be found using the following SMS to the phone number (not data number) of the SIM in the modem:

INTELIMAX.PARK.WANIP

The Maxon Australia support team has recently received a large number of enquiries about high data usage from Telstra. Bill shock is something that no one likes to we would like to provide some reasons for the data usage and also some things you can do.

What is happening?

Many customers have been experiencing high data usage on their modems. This usage is as high as 2GB in a 24 hour period. Customers have noticed this usage on their Telstra data logs have seen this usage recorded as chunks of 120MB (or 117MB) data, Telstra’s default data block record size.

Why is this happening?

All customers who have experienced high data usage are on the 'telstra.extranet' APN. This APN provides the 3G routers with a public dynamic IP address. Public IP addresses are useful if you need to access your 3G modem remotely, however these addresses are also susceptible to random hack attempts. This is the most plausible reason why the data rates have recently shot up.

How to fix this issue and/or remove the risk of this happening in the future?

Changing to a private IP address is the only sure way to remove the risk of random, sustained hack attempts. This means changing to either the ‘telstra.internet’ APN or using a private IP WAN service such as maXwan. All Maxon modems (except for the Datamax) can be configured via SMS, so if you need to change back to 'telstra.extranet' at any stage this can be easily done.

AT over IP now supported by the Maxon Mutlimax

Wednesday, 18 September 2013 04:31

AT over IP allows the user or user equipment to send an AT commands over an IP network to a specific TCP port. Normally a direct connection to the COM Port of the modem is required to send AT command, however this method may not be practical for certain applications. This functionality is very useful for equipment wanting to send SMS messages over the IP network and also in Clear SCADA applications.

MTEL completed a maintenance run throughout the Far Northern Region. Maintenance runs perform checks on the antenna and transmitter systems, and batteries are replaced in systems were the age of the battery is 4 or more years. 20 sites were visited, nearly all were in excellent condition considering the lashing of two cyclones in the last few years.

In addition 6 sites were upgraded to Wireless Broadband (W2B) front ends. Mt Isa, El Arish, Herberton, Milla Milla, Ravenshoe and Port Douglas. These sites have the new Intelimax modems from Maxon. The site below is Pt Douglas system which is amongst one of the busiest auxiliary system in the state. Read the full story here......
