Tele2Mobile GSM/GPRS Modem - Key Features
• Quad-band - GSM/GPRS/SMS compatible• Power output - 2W @
850/900MHz – 4W @ 1800/1900MHz• Internal rechargeable battery
supports low DC power output from host meters• Modem operates from
input voltage 6 to 16V at 800mW supply (80mA at 10V)•
‘Host-independent’ operation• CSD rate up to 14.4Kbps (Modem
battery supports up to 30 minutes CSD call time after 20 hour auto
recharge from meter interface - Typical daily 30-minute profile
reads require 2 minutes or less depending on data collection system
and meter-protocol communication efficiency)• GPRS Class 1 -
9600bps (‘Always-On’ mode for Fixed-IP operation requires only 12mA
standby current to support incoming connection from remote data
collection systems)• Internal TCP/IP stack• Full
auto-answer/auto-dial capability• True RS232 allows meter to
modem/host interface cable up to 15 metres long• AT-compatible
command set for modem set-up• DC power operation and no AC
connection means installer safety, low cost & easy
installation• Remote modem set up and diagnostic monitoring
capability• Small size (60x55x25mm) and low weight (90g approx) =
low transport cost
A Tele2Mobile model with low power sleep mode for telem-etry is
available
About METMOTEC
METMOTEC™ is a trading name of an English private limited
company providing marketing consultancy to AMR companies since
1994, which in 2010 also became a supplier of M2M network
connection products under the METMOTEC brand. The company engineers
and supplies custom M2M network connection solutions which include
interfacing and battery packs for �eld modems and instruments.
About The IMC Group Ltd
IMC manufactures its own products providing direct control over
quality assurance and delivery schedules. IMC produce and sell an
extensive range of data-logger and alarm products that employ
Jekyll GSM modem technology, so the company itself is dependent on
highest possible quality modems as much as its customers. Learn
more about The IMC Group and its range of products at
www.the-imcgroup.com
Special modems from METMOTEC can be connected to meters via
optical ports, such as on this PRI Premier meter
Automated production at The IMC Group factory in United
Kingdom
Top: The Tele2LAN Modem. This product provides Meter-to-Ethernet
serial connection and can also operate as a meter Webserver. It has
Watchdog and Voltage Reset for reliable operation, features not
found on some comparable devices. It is supplied in a plastic case
for protection and safety.
‘Pocket Modem’ Format. The Tele2 range is based on a ‘pocket
modem’ format around 60x55x25mm for personal computers of the early
1990’s applied to UK CoP5 electricity meters. This format is still
an uno�cial industry standard for UK CoP5 and similar meters, most
of which were designed to accommodate it physically and
electrically.
“Pocket” Modems versus Panel-Mount and Rail-Mount Modems
Industrial modems come in diverse sizes, from various compact
and pocket modems to ‘brick’ sized products (typically including a
panel-mount format according to DIN 43857-5). Large panel-mount
modems in general o�er little e�ective di�erence in communications
features compared to compact and pocket modems. Panel-mount modems
can be up to 16 times greater in volume than the Jekyll pocket
modems and some have in-built AC/DC power supplies which require an
electrician to install for safety reasons; they may have several
types of alternative host interface (RS232, RS485, Current Loop
etc) usually redun-dant in a given application; they may have
additional connections for water and gas meters, for example, which
can also be a redundant expense in single meter only cases. In
fact, ‘small is better’ where the application is closely de�ned.
Small size means: Easier �tting; less transportation costs; less
components to fail; more environmen-tally friendly (less plastic
and less power consump-tion); and lower price.
Why buy Tele2Mobile GSM Modems?Meter operators rely upon a
relatively limited number of GSM modems suitable for I&C
meters, some of which do not have all the features ideal for the
metering environment. Other issues are product reliability with
continuity of communication, operating lifetime, security &
continuity of product supply, and dependable delivery. Jekyll o�er
the following advantages to satisfy these concerns:
• Jekyll has been in the electronics business since 1984 and
since 2007 a part of The IMC Group Limited, a large and
successful electronics company
• Jekyll has supplied tens of thousands of GSM and PSTN modems
in the
last 20 years.
• Customers have included leading European meter manufacturers
and
meteroperators in UK and other countries
• The Tele2Mobile modem has a successful 10 year working track
record
in electricity meter and remote telemetry installations
• Current users include major electricity meter operators in
UK
• Top grade technical support from The IMC Group engineers
• Easy installation plus remote online support and management
of
modems
• The Tele2Mobile is designed for reliable remote unattended
operation
About ReliabilityModem reliability is a perennial issue for
meter operators because of the di�cult operational and
environmental conditions found in metering. I&C meter networks
are characterised by many thou-sands of meters dispersed over a
wide area, often in hard to access sites. Failures in such networks
present signi�cant logisti-cal issues and disproportionate costs in
attending to relatively low value equipment, or low revenue sites.
Minimising modem communication failures is achieved by Jekyll
through direct management of quality control in manufacture, and in
design features that anticipate causes of failures in metering
environ-ments. Tele2Mobile modems incorporate the following
compre-hensive functions that ‘reset’ them, thus minimising
non-communicative conditions:
• Voltage Reset – If the supply voltage to the modems drops
below its working voltage the modem processor and circuit is held
in Reset until the supply voltage has recovered
• Watchdog – If the modem processor crashes, the onboard
watchdog will reset the processor
• Data Timeout – When in data mode if no data is received via
its serial port for 120 seconds, the modem will terminate
connection
• Carrier Timeout – If the carrier signal is lost while in data
mode for longer than 40millisecs the modem will terminate network
connection
• GSM Auto Re-Registration – GSM devices can lose network
connection for a number of reasons, including network causes. On
the Tele2Mobile there is an automatic, controlled ‘power- down’
function that disconnects the modem from the network. The modem
then re-powers, reconnects to and re-registers with the GSM
network. This is done daily to provide continuous network
connection and stable operation.
