H7030 Data Service Center |
1. General
Hongdian H7000 mobile data communication system
is developed at basis of 2.5 generation mobile
communication network. It is a packet switch
network operated over existing GPRS or CDMA 1x
network to provide a new type of packet data
service. Because of the system works at operator's
existing network, it gives H7000 system a good
coverage, low cost and flexible configuration. Also
it is reliable and easy to maintain. Therefore, it
is the best way to transmit interrupt, burst data
and
multipoint at different site.
H7000 mobile data communication system consists
of data center and GPRS/CDMA DTU. The data center
can transmit and receive GPRS, CDMA DTU data at same
time.

| Maximum GPRS bandwidth can be up to
171.2Kbps, and maximum CDMA 1x bandwidth can reach 300Kbps.
However, only 40~100Kbps GPRS bandwidth and 100Kb/s CDMA
1x bandwidth can be utilized at actually situation. It works
at TCP/IP protocol, and provides the access for
Internet and other data communication.
H7000 Mobile Data System provides a high speed, always online
and
transparent virtual lease line between remote site
and central network. The main application areas
are focused on power supply and industry supervision,
traffic control, securities and finance, utilities
and so on. With the transparent data transmission
features and variety of
applications, the H7000 system can be configured as
a virtual private network. H7000 GPRS/CDMA mobile
data communication system consists of:
- H7118 GPRS DTU: RS-232/422/485 interface,
high performance,
- H7161 GPRS DTU: Ethernet interface,
- H7612 CDMA DTU: RS-232/422/485 interface,
- H7661 CDMA DTU: Ethernet interface,
- H7710 GPRS/CDMA DTU: RS232/422/485
interface, common platform, supports GPRS or
CDMA 1X network,
- H7031 Data Server Kits: User data center
server, provide the GPRS/CDMA 1x packed data
protocol conversion. It is a set of develop kits
for user to integrated with their applications.

2. H7030 Data Service Center
H7030 data center is designed for transparent
data communication; it provides user application
program interface, and coverts network protocol. It
also manages DTUs on the network, and
displays the DTU status. There are two types data
center available.
- H7031S Data Center Development Kits
Inside of the software development packet, there are demo (gprs_s_demo) programs and develop libraries
(gprs_server.lib) for developer to integrate
with their applications. The gprs_server.lib is
written at VC++6.0 environment, and runs at
Windows platform. If you have special
requirements, please contact with Hongdian
research and develop center for details.
It is a router for Data Center protocol
conversion. It works at embedded hardware and RTOS
platform, converts the data from/to DTU, and
then sends to user's data center. It provides an IP
network interface to communicate with the
application data server.
