With the switching centre
IPTBridge it is possible to communicate with thousands of IP-based
devices (e.g. GPRS-modem, LAN-modem) via internet. All devices
establish a TCP connection to the IPTBridge and after that, these
devices are always ready for communication. The IPTBridge acts as a
switching centre between the devices (modems) and the AMR-system and is
able to manage up to 50000 devices. After the devices are logged in
successfully on the IPTBridge, the IPTBridge can establish a vir-tual
connection between the AMR-system and the device on request of the
AMR-System. Now there's a transparent and bidirectional communication
bet-ween AMR-system and the device possible. The IPTBridge uses the DIN
43863-4 standard. This means, that devices of other manufacturers,
which have implemented this standard, are supported. Besides this
standard other proprietary protocols are implemented: The protocol of
Bär Industrie-Elektronik GmbH and the protocol of Landis+Gyr. If the
AMR-system communicates only via serial Com-ports, an additional
software component, the Virtual Modem-Pool, is needed. This software
converts the serial communication into TCP/IP communication and
establishes a communication line between AMR-system and IPTBridge. With
these software components, the IPTBridge and the Virtual Modem-Pool, it
is possible to extend existing AMR solutions in an easy way.
Following functions are possible:
► IPT-Client: connection to
a GPRS-Modem (e.g. UniMod GSM-4)
► Null-Modem: connection between two virtual COMs at one PC’s
► PC-PC-Client or Server: connection between several PCs via LAN
► COM-Multiplexer: several COMs via one serial communication line
► LAN-Modem: connection to an IPT-Device (e.g. UniMod Ethernet)
