Design of the Telephone System for Metallurgical Factory and Mine
Introduction
The majority of metallurgical plants and mines employ telephone systems to ensure the efficiency of their operations and communication between sites. Telephone systems are responsible for organizing communication, encrypting calls, and protecting calls from external interference. Since its establishment in 2006, the Guangzhou Metallurgical Plant and Mine in China has relied on a traditional PSTN telephone system that is now outdated and inadequate for its increasing network communication needs. Therefore, Guangzhou Metallurgical Plant and Mine Management has decided to completely replace their existing system with an advanced version.
Phone System Architecture
The architecture of the Guangzhou Metallurgical Plant and Mine’s new telephone system is requires a locally distributed system that provides highly secure and reliable communication for internal and external users. The system will be based on a combination of Session Initiation Protocol (SIP) trunking and Voice over Internet Protocol (VoIP) technology. This system architecture will allow the transfer of calls between two different sites, while ensuring secure communication. It will also integrate dual networks, wherein one is responsible for forwarding calls between local sites, while the other provides external users with access to the system. Furthermore, the system will be designed to provide users with the ability to instantly access data, and make and receive calls using multiple devices.
Hardware Setup
The new system will be based on hardware such as Cisco Unified Communications Manager and Cisco Unified Contact Center. Cisco Unified Communications Manager is responsible for the administration of the system, while Cisco Unified Contact Center provides customers with automated services, such as call routing and wait times. In addition, the system will include a firewall and IPS system, as well as routers, switches, and other networking devices. The hardware will be configured to ensure secure and reliable communication, as well as providing users with features such as call waiting and call forwarding.
Software Requirements
The software system will include a variety of tools such as VoIP, Call Recording, and PBX systems. Moreover, the system will include software for monitoring the network and system activity, including call activity and the flow of data. Furthermore, the software system will include a voice mail system for providing users with the ability to record messages.
System Security Requirements
In order to ensure the security of the system, strong password policies and regular updates are required. Furthermore, the system should be configured to use secure protocols such as SSL and TLS. Moreover, the system should also be configured to use an approved encryption algorithm, as well as access control lists to limit access to the system. Additionally, the system should include tools for monitoring network activity, data flow, and user activity.
Conclusion
The Guangzhou Metallurgical Plant and Mine requires a secure and reliable telephone system for efficient communication between sites. The system must be based on a combination of SIP trunking and VoIP technology, utilizing hardware, such as Cisco Unified Communications Manager and Cisco Unified Contact Center, as well as software such as VoIP, Call Recording, and PBX systems. Finally, the system must ensure the security of the calls and user data, indicating that measures such as SSL and TLS, password policies, and access control lists are crucial.
