Industry & Government
Solution
System Overview |
Industry & Government greatly speed up the process of the
information construction, In the most of areas, establish IP
data network that cover the all system. Adopt the tree-type
structure work out, Top-down managing Industry and Government,
The communication between the departments of all-level is extra
important. By the internal data network, constructing IP, We can
greatly reduce the internal communication expenses, promote the
managing and working efficiency, and and boost the data network
utilizing ratio, At same time, The IP telephone special network
is an effective measures to enhance the internal commutation
safety. EWAY aim at the requirement of Government and Industry,
presents to IP telephone network system as the solving scheme
(project). This scheme can be used for many organizations such
as all level Government department, tax business, public
security inspect and law court, party and administration system,
post, finance, insurance, electric power, custom etc. The system
equipment passed the enter network test which be carried out by
Information Industry Board and National Finance laboratory and
other authority organizations. The system equipment had applied
to almost over 100 large-scale IP telephone network.
System Application Solution.
Government, Industry VOIP system structure figure.
Scheme introduction.
Install IP voice equipment at data network of all levels work
organization, By means of A/D E1
relay interface, connect the original office telephone
environment (programming telephone
switchboard, line city MAN, telecom virtual network etc).
Realize IP data network communications, In the inner office
telephone of organization. By mean of IP telephone network We
can take a long distance call that outside the organization.
Using the called cities IP Voice Gateway , put through the local
PSTN MAN , thereby don't pay any charge for a long distance
communication.
Establish a set of IP telephone network managing and calling
statistical system, Calling identification to IP Voice Gateway
in the IP telephone network., Allocate the network numbers,
Equipment web management, call statistic, provide with bill and
report forms.
Kernel Office Organization province level
Due to the bigger office scale, Usually you have configured
programming-control telephone switching device. We suggest you
to configure a digital relay IP Voice Gateway , connect the
original programming-control telephone switching device using E1
relay. When user dial an inner call, The programming-control
telephone switching device connect to IP data network by means
of digital relay IP Voice Gateway.
Middle-sized Office Organization City level
There are more office numbers, Therefore you usually configure
office telephone switching device or telecom virtual network. We
suggest you to use CNG series IP Voice Gateway that have an
analog Voice interface, connect office telephone switching
device or telecom virtual network by means of inner interface of
the IP Voice Gateway, and connect to PSTN MAN.
The CNG series IP Voice Gateway have intelligent call and route
select function. Using switching device the user don't change
original dialing habit, judge the calling router by IP
Voice Gateway. The calling inside city meet WAN, The calling
inside special network meet IP network, When IP telephone
network turn off, The calling meet PSTN WAN automatically. Then
the PSTN WAN and IP back up each other. But we give priority to
IP telephone network.
Basic office organization (county and section)
Usually there are less worker's number, A majority of them
don't have a telephone switching device. They use line telephone
or telecom virtual network. We suggest you to use CNG series IP
Voice Gateway that have an analog Voice interface. Turn on desk
office telephone inside, connect to PSTN WAN or telecom
virtual network, In this way we make the original desk
office telephone
one phone, two numbers both WAN number and special network
number. Judge the calling router by IP Voice Gateway. The
calling inside city meet WAN, The calling inside special network
meet IP network, When IP telephone network turn off, The
calling meet WAN automatically. The IP Voice Gateway has
switching function itself, The original office telephone
can realize inner communication between them.
The scheme characteristics
Don't change user's original dialing habit.
Realize one phone have two numbers function.
Dialing to route automatically, When user dial a WAN
number turn on PSTN WAN, when user dial a special phone
turn on IP network.
When IP network has some malfunction, The calling jump to
PSTN WAN, The IP Voice Gateway gives a voice prompt.
Support IP phone meeting system.
Support IP phone meeting system.
Support VoIP applications in all kinds of network .Have robust
adaptation to network resource. It can be used for making
network consisting of SDH, DDN, FR, wireless network
bridge gateway, satellite communications, VPN and
Internet.
System components
Central organization (province level )
CNG8000 Digital relay IP Voice Gateway CNG8000
We suggest you configure a Digital relay IP Voice Gateway
CNG8000 in the central organization, connect original
program control phone switching device using digital E1 relay
line. CNG8000 IP Voice Gateway provides with 1x16E1 digital
relay, Supports china and ITU-T H.323V3/4 standard,
Supports china No.1/ ISDN PRI signaling.
Calling manage and control central system
The system includes GK module, calling statistic module
and network manage module. GK module is responsible for calling
identification of the VOIP phone network system., the port
number distribution, the calling number resource management, the
calling route management and bandwidth management. The calling
statistic module is responsible for calling statistic of the
whole network IP phone numbers, calculating the charges,
creating a calling bill and query. The network manage module is
responsible for setting long-distance manage of terminal
equipment in the IP phone network, the software upgrading,
performance monitoring, breakdown alerting and provides
with system log and network topological information.
City /county level office organization
CNG2000/3000 IP Voice Gateway: It is a multi-function IP phone
gateway device based on module design, has 4-16 line phone user
relay interface (FXS), or loop relay (FXO) select, can be
used for middle-scale basic units
Villages and towns level basic office
CNG1000 IP Voice Gateway: It is a small type IP Voice Gateway,
has a 2-4 line phone user relay interface (FXS), or loop relay
(FXO) select, can be used for middle and mini type office
organization. |
