DTS-1100 Advanced Exchange is an international standard electronic switch that is used for local, local / Tandem and CENTREX of PSTN (Public Switched Telephone Network) and ultimately ISDN It has been developed to be a flexible exchanger in various network types such as intelligent network (IN).

The DTS-1100 is an advanced system developed by applying the latest technologies in the fields of computer, semiconductor, communication, and software. It is suitable for all applications in terms of external size, performance, service flexibility, and adaptability to network environment.

DIS-1100 advanced system is one of existing and commercialized services such as voice (Local / Tandem), CENTREX, ISDN (2B + D, 30B + D), and common line signaling (CCS NO.7) functions. It has been developed to play a major role in a comprehensive information communication network that can be accommodated by all systems.

The main design concept of the DIS-1100 retrofit is the open archi-recture, which provides flexibility and modularity to facilitate system expansion and modification and to make it easier to improve the system as technology advances. ) Is adopted.

In other words, the system structure is designed to minimize the impact of technological development, and is designed in consideration of economics to provide advanced services to subscribers at a more economical price.

Key considerations when designing the DIS-1100 Advanced System include:

* Simplify hardware by maximizing modularity

* Realization of economical efficiency by maximizing hardware usage efficiency

* Economic feasibility by maximizing software processing function

* Increased system configuration flexibility through subsystem combination

* Maximization of operation and maintenance by simplifying hardware

* High performance and high reliability

* Enhanced software implementation and maintenance

* Easy to add new features

The DIS-1100 retrofit can be configured in a variety of packages.

The DIS-1100 is a system that can accommodate up to 8,192 subscribers and 1080 channels of relay lines, and has a distributed control concept that can handle 1,200 Erlang traffic and 150,000 Busy Hour Call Attempts (BHCA). The capacity is extended by 1500 lines.

The collection ratio may be 4: 1 or 8: 1.

The main specifications of the DIS-1100 Enhanced Exchanger are shown in Table 1.

Distributed control structure:

The DIS-1100 retrofit incorporates a redundant processor architecture with general purpose 32-bit and 16-bit microprocessors to increase modularity and improve reliability.

The control function is implemented in a control layer structure of two levels of the upper processor and the lower processor.

The upper processor, called the Main Processor (MP), performs higher functional tasks such as call processing, number translation, exchange control, multi-frequency signal processing, system maintenance and operation, and the peripheral processor (PP). The subprocessor, called Peripheral Processor, performs tasks that require real-time processing of the lower layers, such as path detection, analysis, and line signal processing.

Function Distribution is performed by distributing various functions to the processors, and the PP and call processing processors adopt a load distribution method for easy addition as the system is expanded.

Operating system:

The operating system of the DTS-1100 advanced system basically carries out process management by FIFO (First In First Out), and requires interrupt processing and real-time processing to perform urgent processing according to the case. The Real Time Clock is operated to perform the function.

In addition, interprocessor communication processing is performed, and control system redundancy processing is performed.

Programming language:

The DTS-1100 variant adopts the C language for software programming, and the Assemble language for hardware matching that requires real-time.

Redundancy:

In order to increase system reliability, all the major parts of the DTS-1100 retrofit, ie MP, PP, etc., are duplicated, including all control systems, switches, network devices and signaling devices.

In this regard, in the Centrix / Attendant console device connected to the DTS-1100A electronic switchboard, the message waiting function is a function in which the call is automatically transferred to the designated device when the called party is not answered after the call transfer. After receiving a certain message in, it notifies the called party of the message waiting status and then notifies the waiting message according to the request of the called party.

In addition, it performs the function of answering and receiving a message transferred to a Centrix / Attendant console device, delivering a received message on demand, and driving and releasing a message lamp of a subscriber telephone.

An object of the present invention is to provide a message in a centric / attendant console device that receives a certain message from the centric / attendant console device, informs the called party of a message waiting state, and then informs the waiting message according to a request of the called party.

3 is a flowchart showing step by step an embodiment of a message waiting method in a CENTRICS / ATTENT console according to the present invention.

First, when a call is a subscriber whose message waiting function is registered and the call is received, when the call is transferred to the device from no answer or busy state, the lamp of the [MSG] key blinks every 0.5 or 1 second intervals, For example, the call waiting water state is displayed on the liquid crystal device (LCD) panel (300, 310, 320, 330).

At this time, the number of call waiting is displayed on the fourth digit of the call waiting number (up to three).

When you press the [MSG] key to respond, the lamp of the [MWI] key displays the current message waiting status, and if the message is already waiting, the flashing repeats at 0.5 or 1 second intervals and remains on if there is no message waiting. (340).

Thereafter, when the calling party leaves a message, the device causes the lamp of the called phone to be driven when the [MWI] key is pressed (if there is no existing waiting message) (350, 360).

When the recipient checks the lamp on the phone and checks the status of the lamp on the phone, and the device requests a call to check the message, the lamp of the [MSG] key repeats blinking at 0.5 or 1 second intervals when the device checks the message. Press the [MSG] key to make a call and notify the called party of the received message, use the [MWC] key to release the message waiting [MWI] function, and press the [MWC] key to turn on the [MWI] lamp. It is switched to and indicates that there is no message waiting (370, 380, 390, 400).

When registering / cancelling message waiting function, it is possible to register / cancel message waiting function to subscribers individually.

To register, press the subscriber number and press the [MWI] key to register the standby function to the subscriber. To cancel the standby function, press the subscriber number and press the [MWC] key to cancel the message waiting function of the subscriber.

As described above, the present invention performs a waiting function such as notifying a waiting message according to a request of a called party after receiving a schedule message from a Centrix / Attendant console device, notifying the called party of a message waiting state. By doing so, the standby function can be realized.
