Employing digital exchange network, decentralization control by
computer, and C language programming, Model KTJ4H Digital
Program-controlled Dispatching Communication System has the
advantages of advanced technology, pretty appearance, small volume,
energy saving, flexibility, high reliability, complete functions,
and convenience for maintenance, and is suitable for commanding and
dispatching communication for enterprises and public institutions
of coal mine and other industries.
The system has complete trunk interfaces and signaling system, can
be configured to many kinds of special network or dispatching
network wholly digital or digital/analog mixed, convenient for
centralized maintenance.
All the circuit boards of the system employs HCMOS integrated
circuits and special exchanger chips, and the slots of the circuit
boards can be interchanged, convenient for function and capacity
configuration.
The system is conformed to the standard issued by Ministry of Posts
and Telecommunications in signal, transmission, synchronous mode
and charging, and the software of new version according to
different requirements also can be provided. |

| | Have powerful dispatching functions such as single-key direct
calling, transferring, forced cut-in, forced break, conference,
hold-on, group call, night service and so on. | | The system supports large-scale 48-parties conference. | | The system can set up multiple dispatching desks, which showing
number, unit, data of incoming call user in plasma screen in
Chinese. | | Equipped with touch screen, the dispatching desk can realize
computerized dispatching. | | The system provides multi-interfaces for digital trunk （2B + D, 30B
+ D）, carrier trunk, E/M trunk, loop trunk, etc, can form
multi-level special network or dispatching network in digital or
digital-analog mode, realize equal-length dialing and is convenient
for centralized maintenance. | | The system supports multi-type terminals including normal automatic
telephones, I.S. automatic telephones, surface amplifying device. | | The system has functions of internal user limitation, multi-level
authority and multi-level priority, the high-level user can cut in
the low-level user. | | The system has functions of music hold and validation and
computerized operator. | | The extension telephone has function of giving number and time. | | The system provides signal standard, transmission standard,
synchronization mode and charging feature which conform to the
standards issued by the previous ministry of posts and
telecommunications, and the new-version software according to the
requirements of different communication network also can be
provided. |
