Specific features and functions of the meter and modem as a system component may not be available.
E550 Series 2
The E550 Series 2 meters equipped with a powered RS232 port support
the use of ETM MSM modems. These are meters with the .07 or the .37
options of the meter.
The modem fits under a transparent terminal cover with the part number
P74 111 0039 0. This meter terminal cover can be ordered separately if the
ETM MSM modem is being added to a pre-installed meter. It may be larger
than the terminal cover that was originally equipped with the meter and free
space must be available.
E550 Series 1 and
E650 Series 3 meters
The E550 Series 1 meters can be equipped with a RS232 port that can be
used by the ETM MSM modems. These are meters with the .02, .42 or .62
options of the meter.
The E650 meters can be used with the ETM MSM modems provided that it
has a RS232 port in channel 1. This is accomplished by equipping the meter
with a choice of CU-A5/+, CU-B1/+ or CU-B4/+.
The modem is fitted to a terminal cover adapted for the CU-ADP2 attachment. These meter terminal covers can be ordered separately if the ETM
MSM modem is being added to a pre-installed meter. It may be larger than
the terminal cover that was originally equipped with the meter and free
space must be available to use this solution. The modem is mounted on the
terminal cover as opposed to the case where the E550 Series 2 where it
sits under the terminal cover.

7/34
SIM card installation
This section deals with installing the SIM card (see also section 7 "SIM cards")
into the modem which is always done while the unit is not powered up. For
an UMTS network, the SIM card is often referred to as an USIM card.

SIM card must provide GSM service
The SIM card must include a GSM CSD (Circuit Switched Data) service as
a minimum. CSD service is required to update the firmware, if necessary.
SIM cards that provide only a GPRS service are not supported. Not having
a CSD service releases Landis+Gyr from support costs associated with
software issues.

SIM card must support SMS receiving and sending
The SIM card must support SMS receiving and sending in order to support
remote programming and other features.

Keep SIM card contacts clean
The SIM card is an electronic component. As such, the metallic contacts
must be clean from oils and other contaminants when installed into the
modem. Failure to keep the contacts clean may lead to the long term corrosion of the contacts between the SIM card and the modem. This can result
in the intermittent or permanent interruption of the modem's operation.

MSM solution features
4.1
Choosing between MSM modems
Currently there are two MSM modem suppliers (see section 1 "Background")
and there will be new suppliers being brought into the supply chain. This
document only contains information about the ETM modem.
Landis+Gyr recommends that customers evaluate each MSM modem individually to ensure that it has the specific features that the customer requires. Furthermore, Landis+Gyr recommends that customers use only the
features that are part of the MSM modem feature set as much as possible
to ensure compatibility to future MSM modem solutions. Vendor specific
features should be avoided whenever possible and Landis+Gyr will make
every effort to increase the feature set from time to time.
Some features are vendor specific. Although these features are often useful, the use of these vendor specific features will generally cause an inherent incompatibility between MSM modem suppliers. For example, if the a
vendor specific feature is used, the user will no longer be able to use another MSM modem that lacks this feature. Multiple sources reduce the risk
of being locked into a single supplier and users need to be aware of this.

MSM modem features
Landis+Gyr intends to support a core set of features that will always be part
of the MSM feature set. These are described in this section. Features that
are not part of the MSM features are indicated as vendor specific features.
The ETM modems are available in four configurations (see table "Modem
variants" in section 2 "Meters supporting ETM MSM").
4.2.1
Mounting
Under the meter
terminal cover
The MSM modems ETM8120-2 and ETM8130-2 are designed to be
mounted under the terminal cover of E550 meters and get power from the
powered RS232 connector of the E550 meter. The modem fits under the
terminal cover and is protected under the utility seal.
In an adapter
CU-ADP2
The MSM modems ETM8120-3 and ETM8130-3 are designed to be
mounted in an adapter CU-ADP2 fitted to a terminal adapted for the attachment of the CU-ADP2. These MSM modems get power from the CU-ADP2.
The CU-ADP2 is protected by a utility seal and can be wall mounted, DIN
rail mounted or terminal cover mounted. This is a vendor specific feature.
4.2.2
Power supply
Via powered
RS232 interface
The E550 meter supplies the power to the MSM modems ETM8120-2 and
ETM8130-2 via the powered RS232 interface (pin 4 and 8 of the RJ45 connector, see figure 6). The supply to the modem is enabled when either of
these conditions is met:

one phase has more than 100 V applied

two phases have more than 58 V applied with a phase angle of at least
90 degrees between the phases
In addition, if the modem draws more than approximately 250 mA average,
the supply to the modem will be interrupted and polled periodically.
Via adapter
CU-ADP2
4.2.3
The CU-ADP2 supplies the power to the MSM modems ETM8120-3 and
ETM8130-3 via its 10-pin plug. The maximum current is 450 mA. The use
of an external power supply is a vendor specific feature.
Flow controlled RS232 connection to meter
The MSM modems ETM8120-2 and ETM8130-2 use pin 2 of the RJ45 connector as a CTS (Clear To Send) flow control signal, the MSM modems
ETM8120-3 and ETM8130-3 use pin 1 of the RJ12 connector (see figure 6
below).
The flow control ensures reliable communications between the meter and
the modem when there is congestion between the network and the modem.
This prevents the overflow of buffers.

The use of an RJ12 connector is a vendor specific feature. The CU must be
a variant that supports flow control in order to be used with the ETM modem.
Such modules are designated with the plus (+) option at the end of the name.
The CU-B4+ is suitable while the CU-B4 is not.
4.2.4
Telecommunication services
GSM CSD
All MSM modems support a circuit switched data (CSD) service that
emulates a traditional analog phone line modem connection.
Fixed IP GPRS
All MSM modems support a TCP based service operating over an IP based
network. The MSM modems ETM8120-2/3 support GPRS multislot class
12, the MSM modems ETM8130-2/3 GPRS multislot class 10.
The user can configure the APN (access point name), user ID and password and other GPRS parameters. The implementation includes a programmable ping gateway address. When this gateway does not respond
after a number of tries, the modem is assumed offline and any current IP
contexts are reset and a new GPRS session is started. This ping packet is
only sent when there is no active data transmission for an extended period
of time.
3G UMTS
The MSM modems ETM8130-2/3 support 3G UMTS (download and upload
max. 384 kbit/s) and HSDPA (high speed downlink packet access with enhanced download capacity of max. 3.6 Mbit/s). This is a vendor specific
feature.
SMS
The ETM modems support the use of SMS messages to accomplish
different commands. This may include simple configuration, diagnostic
commands or control commands. This is a vendor specific feature.
4.2.5
Frequency bands
Quad band
The MSM modems ETM8120-2/3 are quad band modems and designed to
operate and switch automatically to use the frequency band 850, 900, 1800
and 1900 MHz depending on the mobile network.
Dual band
The MSM modems ETM8130-2/3 are dual band modems and designed to
operate and switch automatically to use the frequency band 900 and 1800
MHz for GSM/GPRS or the frequency band 900 and 2100 MHz for UMTS
depending on the mobile network.
4.2.6
Transparent modem
All MSM modems are transparent modems meaning that they are protocol
independent. They do not respond to dlms or IEC commands but rather
transparently send the data from end to end over a non-transparent channel.
Remote commands to configure the modems or to take modems offline is
done through escape sequences and AT commands specific to the modem
supplier.

D000044190 en a – Using E55C ETM MSM Modems – Application Note
MSM solution features
4.2.7
15/34
Received signal strength indication
E550 meter
All MSM modem software is integrated with the E550 meter to enable the
measurement and indication of the GSM network signal strength on meter
display during installation. In order to have this function enabled, the E550
meter must be configured to display the "Antenna Field Strength on/off" in
the service menu. MAP tools can also be used to read the signal strength
using an optical head.
E650 meter
The E650 meter does not support this feature. With the MSM modem
ETM8130-3 used with E650 meters the signal strength is only indicated on
the green LEDs (see section 6 "LED display").
4.2.8
SMS alerts
All MSM modems software is integrated with the meter to send SMS
messages. When the modem is busy with other activity such as during an
actual data transmission, the SMS message has a lower priority and
retransmissions will be repeated.
E550 meter
The E550 meter's powered RS232 interface is the only interface that can
generate SMS alert messages.
E650 meter
E650 meters ZxD300/400xR with an integral RS232 interface must be connected to the ETM MSM modem via this interface to send SMS messages.
This is available starting with firmware release version B32.
E650 meters ZxD300/400xT with a CU-Ax or CU-Bx with RS232 interface
cannot be used to send SMS alerts.
Because the modem uses a single phase power supply – even when the
meter is equipped with an auxiliary power supply option – SMS transmission may be unreliable. The CU-ADP2 power supply has sufficient charge
to power the modem for up to 8 seconds. This is a vendor specific feature.
4.2.9
GSM/GPRS time window support
Dynamic IP mode
Only the dynamic IP mode requires a dedicated time window for IP communication and a separate time window for GSM CSD communication. The
ETM modems do not support dynamic IP mode.
Fixed IP mode
When operating in fixed IP GPRS mode and when there is no active IP
communication session, the ETM modems are capable of answering a
CSD call that comes in. This means that GSM/GPRS time windows have
no real meaning for this mode other than to limit the time registered on a
network. The E550 meter is able to define a time window when it is disconnected from the ISP. The E650 does not support a GSM time window.
Class B
The MSM modem based on the TC63i modem is capable of answering a
CSD call while in GPRS mode when listening but not during an active data
transfer. The MSM modem based on the EU3-E is not capable of
answering a CSD call while in GPRS mode when listening. . In all cases,
during an active GPRS transfer, an incoming CSD call will cause an
ongoing GPRS communication to fail.
UMTS limitation
The MSM modem based on the EU3-E modem cannot answer a CSD call
while it is logged onto the UMTS network. In some networks, SMS services
are not available while logged into the UMTS network.

MSM solution features
4.2.10 Converge and MAP tools tested
All MSM modems have been tested with Landis+Gyr MAP tools and head
end systems (HES) such as Converge to ensure correct operation.
4.2.11 Remote maintenance and configuration
The MSM modems can be configured remotely. For example, if a parameter that affects GPRS operation needs to be changed due to network
conditions, the ETM MSM modem can be contacted remotely, taken offline
and then reconfigured and re-started.
In addition, should it become necessary to download new firmware to the
meter either to provide additional functionality or to correct bugs, the ETM
modem firmware updates can be downloaded. Carrier charges for data
volume or connection times will apply.
4.2.12 Modem initialization
The meters initialize the modems into a known state that is appropriate for
the proper operation of the modem. This configuration is the same configuration tested by Landis+Gyr during our internal testing of the system.
4.2.13 Robust against incorrect configuration
All ETM MSM modems will revert to GSM CSD operation in the event that
GPRS (UMTS) operation is incorrectly configured or GPRS (UMTS) service
is not available after approximately 10 minutes.
4.2.14 Local programming application
Each modem will tend to have its own programming interface. This is proprietary and highly particular to a specific implementation. This is outside
the scope of the MSM specification.
The ETM modem features a configuration tool using a serial port. Please
see ETM configuration tool user manual for more information. The configuration tool allows the user to:

Read a configuration from a modem and save it.

Write a configuration to a modem.

Execute AT or ET commands using the terminal program.

Select modem options using a graphical user interface.

Enter PIN codes for SIM cards.
4.2.15 Labelling
Labelling is in general outside the scope other than that a specific set of
information will definitely be provided. This includes:
1.
Bar code of the serial number
2.
Manufacturer name and contact information
3.
Product name
4.
Applicable warnings and declarations
Beyond this, any other form of labelling is vendor specific.

Workflow
The workflow defines the steps that the user of the ETM MSM modems
must do to configure, install and operate the ETM MSM modems.
5.1
Installing the SIM card
All MSM modems have a factory default mode that defaults to the GSM
mode. If the modem will only be used in GSM mode, the SIM card can be
installed on-site during the installation or at the utility. The installation procedure is described in section 3 "SIM card installation".
5.2
Configuring the modem
If the modems will be used in GPRS/UMTS mode, further configuration
must be done to configure the GPRS/UMTS parameters.
The configuration of the GPRS/UMTS parameters can be done locally or
remotely.
5.2.1
Local configuration
To configure the modem locally, an ETM programming kit must be available.
This ETM programming kit connects a Windows computer with the ETM
MSM modem without using a mobile network. The advantages include:

the user can see the modem during the configuration

the connection between the PC and the modem is faster than calling
up a modem to configure it

only a single user needs to know how to configure the modems

SIM card installation can be done in a controlled environment and this
reduces the risk of ESD damage.
The disadvantage is that the modems have to be taken out of the packaging in order to perform this programming and resources are needed to
program.
The followings steps describe how the modems can be configured once
the ETM configuration software has been installed on a Windows XP or
Windows 7 computer:
1.
For MSM modems ETM8120-2 and ETM8130-2 detach the modem
from the terminal cover by pressing on the tabs on the side of the
modem holder preferably with a small screw driver. Please refer to
figure 7.
For MSM modems ETM8120-3 and ETM8130-3 unscrew and open the
cover of the adapter CU-ADP2 mounted on the meter terminal cover.
Electro-static discharge can damage the modem
When the modem is detached from the terminal cover or when the cover of
the adapter CU-ADP2 has been removed, the electronic components are
exposed. The printed circuit board is susceptible to electro-static discharge
and this can lead to latent damage to the modem. Always handle the modem by the plastic holder and avoid touching any of the electronic components. Failure to do so will void your warranty.

2.
For MSM modems ETM8120-3 and ETM8130-3 replace the RS232
cable connected to the ETM MSM modem with the customised cable
RJ45 to RJ12 of the ETM programming kit.
3.
Make sure that a SIM card is installed (installation procedure see section 3 "SIM card installation").
4.
Connect the ETM programming kit to a serial port and as well, connect
the USB port of the ETM programming kit to an USB port of the computer. On some computers this may require an extension for the USB
or the serial port.
5.
Start the ETM configuration software tool on your Windows computer.
It should look like this, otherwise select the "Terminal" tab manually:
6.
Click on Set COM Port.

7.
In the "Port" selection field select the serial port to which the ETM
programming kit has been connected, then click OK.
8.
Click on COMx: CLOSED (where x = selected port number). The serial
port will open and the button will be labelled COMx (9600): OPEN.
Maximum supply voltage for CU-ADP2 is 240 V (phase to neutral)
Do not connect phase to phase voltage to the CU-ADP2 WAGO connector,
this would damage the CU-ADP2 circuits.
9.
This next step starts the boot process of the modem and requires that
you enter a key stroke within 3 seconds and so the computer must be
prepared.
For the ETM8120-2 and ETM8130-2, connect the RJ45 to the ETM
programming kit.
For the ETM8120-3 and ETM8130-3, connect the RJ45 to the ETM
programming kit and then apply power to the CU-ADP2 WAGO connector.
10. Press the escape key a few times.
The boot process stops and modem communicates over the serial port
at 9600 baud, 8 bit, no parity and one stop bit.

Remote configuration
To configure the ETM MSM modem remotely, it must be properly installed
and powered. The modem must be at least logged onto the GSM or UMTS
network and ready to receive SMS messages, CSD calls or UDP packets.
There are two supported methods for configuring the modems remotely –
using a CSD call or using SMS messages.
Please note that in some networks remote configuration is not possible
using CSD when the modem is logged into the UMTS network.
Using SMS messages
The sequence of SMS messages to be sent to configure for GPRS mode
are:

ET-ILP=Port (Set the TCP port to Port.)

ET-ISP=Your_Username,Your_Password

ET-IAPN=+CGDCONT=1,"IP","APN_Name" (Set the APN name to
APN_Name.)

ET-IRC=1 (Set the modem to login to GPRS network.)

ET&SR (Reboot the modem.)
To get the signal strength from the modem by SMS:

ETI or ETSEND=AT+CSQ
Each message must be in a separate SMS and the commands are
processed within 5 minutes.
Using a CSD call
Establish a connection using a CSD call with a terminal program such as
Hyperterminal. The commands to configure for GPRS mode are:

ET-ILP=Port (Set the TCP port to Port.)

ET-ISP=Your_Username,Your_Password

ET-IAPN=+CGDCONT=1,"IP","APN_Name" (Set the APN name to
APN_Name.)

ET-IRC=1 (Set the modem to login to GPRS network.)

ET&SR (Reboot the modem)
The command to request signal strength is:


Configuring the E550 meter
The following E550 meter configuration is required when used together with
an ETM MSM modem. The configuration can be set using the MAP120
Parameter Editor (make the settings and then download to the meter).
5.3.1
RS232 port configuration
ETM MSM modems are shipped with a default transmission rate of 9600
bit/s and so meter transmission rate should be set the same. If changes to
baud rate is needed, this must be changed in both the modem and the
meter.
MAP120 tree position
Communication  Electrical Interface  Electrical Interface 1 (Powered
RS232)
The transmission rate of the serial interface is configurable but all system
validation has been performed at 9600 Baud. We do not recommend
changing the transmission rate.
It is possible for the meter and modem to operate at 19200 baud and 38400
baud.
5.3.2
Modem reset configuration
The modems are configured to be reset on a periodic basis. Landis+Gyr
recommend a value of 24 hours. A value of 0 is not recommended for reliable operation of the modem. The reset occurs at 5:00 in the morning and
is repeated based on this configuration parameter.

Meter SMS configuration
The meter can be configured to send SMS messages in certain product
variants. During the meter factory configuration process, the Short Message System option must be selected.
The AT command is AT+CMGS. Note that the phone number format may
use an international format depending on SIM card configuration.
SMS messages are not transmitted if the trigger occurs during a data transfer and because of this it is recommended that the number of repetitions be
set to a value greater than 1 with repeat interval larger than the longest
duration of data acquisition.

RS232 port configuration
The following configuration of the CU works for both IEC and dlms. This
has been tested with GPRS and GSM with the MSM modem ETM8120-3
and ETM8130-3. The RS232 port must be configured for DTE direct. This
mode is designed for intelligent modem operation where the modem is
responsible for handling incoming calls and maintaining an IP context.
No further configuration for the port is required.
The Clear To Send (CTS) option must be enabled to allow the modem to
flow control the data. Data Terminal Ready (DTR) is not used.

5.5.1
Modes of operation
The ETM MSM modem has two modes of operation:
5.5.2

GSM CSD only (factory default)

Fixed IP GPRS/UMTS and GSM CSD
PIN code support
If the PIN code of the SIM is needed, the three green signal strength LEDs
(see section 6 "LED display" will blink and the boot process is stopped.
Enter AT+CPIN=”1234” (e.g. in the terminal section of ETM configuration
software tool).
As an alternative, the PIN can also be entered in the graphical user interface on tab "Main Init", "Miscellaneous" area, entry field "SIM PIN" (highlighted red in the screenshot below) is and then written back to the modem.
5.5.3
Checking the signal strength using the display push button (E550 only)
The signal strength is displayed under the "Service Menu". A detailed
description of the operation is included in the E550 User Manual.
A summary is provided here. From the operating display, press the push
button for less than two seconds to get the "display check" where all the
LCD segments are lit. Press the reset key, labelled R, to enter the service
menu. Press repeatedly the push button for less than 2 seconds until
"AntFS" menu comes up.
The ETM MSM modem must be powered up for at least three minutes until
any attempts should be made to read the signal strength. This gives
enough time for the modem to log into the mobile network.
At the "AntFS" menu, it will display "AntFS Reading" while it measures the
field strength. When value is determined, it will display the value which can
range from 1 to 31, with 31 indicating a very strong signal. The "AntFS
Reading" indication may last for up to one minute before a measured value
is determined.

The following is general information about the SIM cards and network
services that are recommended for use with ETM MSM modems:
© Landis+Gyr

SIM cards should be wide temperature range devices suitable for the
operating environment for the life of the product. This will typically be
temperature range between -25°C to +75°C operation and devices that
are capable of at least 10 years of service life or 200K write cycles. Do
not use SIM cards intended for consumer use.

SIM cards for MSM modems ETM8120-2/3 should be activated for
GSM 850, GSM 900, GSM 1800 and GSM 1900 operation.

SIM cards for MSM modems ETM8130-2/3 should be activated for
GSM 900 and GSM 1800 operation. For 3G networks, UMTS 900 and
UMTS 2100 should also be enabled.

Roaming should be disabled especially for deployments near the
country or network borders.

PIN should be disabled for easy deployment.

GSM CSD (Circuit Switched Data) must be provisioned. This is
needed for remote configuration and maintenance for firmware.
SIM cards that provide only a GPRS service are not supported.

Voice service must NOT be provisioned to deter theft of SIM cards.

SMS sending and receiving services must be enabled.

Private IP address space must be provisioned for the customer
