The Ericsson BP250 business telephone system is a modern state of the art PABX system. The Ericsson BP250 is a wall mounted system consisting of 1 to 3 cabinets that can handle a maximum of 56 trunk lines and 192 extensions in an office environment or 288 extensions in an hotel environment.
The Ericsson MD110 business telephone system delivers a new architecture to support an increasingly mobile work force. The Ericsson MD110 is the world’s most advanced PBX system, offering powerful solutions for today’s and tomorrow’s networks.
The BusinessPhone 250 digital telephone system is the core element of the BusinessPhone office communications solution. It caters for organisations requiring between 20 and 200 extensions at a single location. All system hardware and software in the BusinessPhone solution is modular. This makes it adaptable to a wide range of capacity and functional requirements, and provides the capability for further system expansion and feature enhancement at any time. System Features – BusinessPhone offers an unrivalled range of state-of-the-art features for a phone system of its size. Features like PBX networking, ISDN connectivity to the desktop, integrated cordless extensions and voice messaging, computer-telephony integration (CTI) and complete call center capability. Flexibility is a fundamental part of the BusinessPhone concept, you can use the BusinessPhone building blocks to design the phone system you want.
The following functions are provided by the core BusinessPhone system:
System Enhancements
BusinessPhone 250 systems can be enhanced to provide a variety of advanced call handling and specialist communication solutions. The additional hardware and software modules are fully integrated into the BusinessPhone central unit. These enhanced capabilities include:
Based on a modular and distributed architecture, the Ericsson MD110 provides the foundation for a unified network that supports integrated voice, data and multimedia applications. Because of its distributed architecture, the Ericsson MD110 provides a high degree of fault tolerance and excellent scalability, from a few hundred to 35,000 or more users in an office ,campus or enterprise environment.
Full mobility is supported in any configuration and across multiple locations.Ericsson’s MD110 stands out as an exceptional system that prepares you for the future while providing a cost-efficient solution for today’s business communication needs. Whatever your requirements, today or tomorrow, there is an MD110 system that will exceed your expectations.
Today, there are more than 12 million business users who reply on the MD110 and who have placed their confidence in Ericsson to protect their investment in the future through continuous system enhancements.A PBX is no longer a standalone system for voice communications. Business need a unified network for both voice and data is an integrated part of a larger communications infrastructure. The MD110 is unique in providing a truly open platform that supports all major existing and emerging standards and powerful network management functions to provide the ultimate in flexibility in supporting the flow of all types of information into and out of our organization.
Key Design Principles
These key design principles and the modular system structure gives the MD110 its unique benchmarks and provide customers with benefits in terms of:
Scalability
The Processor Switch Module (PSM) uses its own control system and switch and works as an autonomous system or as integrated part of a larger system. One PSM can have up to 3 interface modules (IFM) and then support up to 640 extensions (traffic and configurations depending). Larger systems are built by simply adding processing and switching capacity (PSMs and IFMs) as the system grows. In this way, integrated systems with more than 20.000 extensions and full feature transparency can be built.
Flexibility (even processor load)
With distributed processing and switching there is always enough processing and switching power in the system to provide the required performance to end users in optimum manner, independent of system size. Investing in a new system does not have to be expensive. Extra processing and switching power are added as the organization grows.
The use of universal hardware and software in the MD110 makes reconfiguration and expansion of the system easier and less expensive.
Reliability and Availability
Since full processing and switching power is distributed to all PSMs a fault in hardware or software affects services only within the malfunctioning PSM, not the entire system.
In addition, each PSM is capable of autonomous operation if the feature link to the rest of the system fails.
The MD110 software is divided into central and regional operating segments. Each PSM contains all the necessary regional software to ensure complete control of intra-PSM call processing.
Communication between PSMs in controlled by central software, which is accessed as required by the originating PSM. The central software is duplicated in several PSMs for added reliability.
Decentralized System on the premises or campus
The modules can be flexibly distributed over a campus area or within the office keeping 100% feature transparency.
The modular structure of the MD110 system in combination with the unique advantages of distributed processing enable Ericsson to supply systems precisely tailored to customer requirements and the physical layout of their organizations.
The MD110 PBX has no predefined system configuration. Instead, users can build up an integrated voice and data network using standardized elements (modules). Processing power (PSMs) and capacity (PSM/IFM) can be loaded where they are needed, to suit users’ unique communication requirements.
