The traditional production of PBX is gradually decreasing, and network telephone is becoming t
The owner chooses a powerful big company to undertake the project. The choice is not the company's reputation, nor the lowest price, but a high-quality and credible system service.For an Integrated Wiring System, engineering rather than materials are embodied. Because the user purchased not only LUCENT. AMP or other manufacturers' cables and connectors, but should be the whole system. Therefore, it is important to select products, but more importantly
that the SIP protocol layer is enhanced in the communication layer. with this open technology, avaya's Aura communication platform enables the association and interoperability between different manufacturers and different devices and services. The platform is positioned between communication infrastructure (such as PBX) and services (such as voice, video, message, video conferencing, and mobility.

reduced by the ability to transmit voice, video, and data over a converged IP network, the Unified Communication solution can save considerable costs for enterprises.Misunderstanding 3:In today's IP communication field, there is no super powerful application.Actual Situation: enterprises use the Internet for different reasons. similar to this, enterprises use Unified Communication for a variety of reasons. Currently, many Unified Communication applications can reduce costs, increase productivit
communication needs and telephone communication needs. However, because there are multiple independent parallel physical networks, there is no connection between them, the construction and maintenance costs are relatively high, and the O M is difficult.
According to the situation in China, apart from the construction of internal telephone systems by itself in specific industries such as power supply and public security, some of the general enterprises and institutions deploy their own data net

Now, the rapid development of the network has entered the G era, and gigabit network transmission equipment is not a new thing. However, as high-end equipment, they also have "high-end" price. Just like the following this original imported Lucent Gigabit network cable, 2 meters long, but to hundred yuan price, if it is ordinary hundred gigabit cable, 4 yuan is enough. Today, I reluctantly give it to everyone to a full anatomy, let us see wh
Summary:
As the industry-leading MPLS core switch, TMX 880 is the newest product in the Lucent Multi-Service Exchange product line, which is designed to smooth the expansion of the existing FR/ATM network of operators and to provide support for the IP/MPLS business and differential IP services. TMX 880 protects the operator's existing equipment investments and greatly reduces operating maintenance costs.
Product Overview
The TMX 880TM is an extensi

Transmission Networks optimized for cloud services
To carry cloud services, carriers need a multi-layer SDN architecture to divide the network into two main components: the network virtualization automation component and the pr
regions. This spin-off can be said to be only for the big tree pruning branches and leaves, so that it produces better, more focused on the main business, innovation to drive their own development, rather than monopoly to develop. The spin-off did not weaken the T. 2. Second spin-off event:The real reason for the decline of the companyInternal: 1. Wall Street and T-t own greed and myopia.

Communication solution runs through a smart phone. The supplier provides a special client software package for each mobile phone, thus limiting the user's choice of the device. If a user is used to a device that the mobile Unified Communication vendor does not support, there will be a huge controversy between the supplier and the user.
Mobile Unified Communication vendor
Mobile Unified Communication vendors can be divided into three categories: Unified Communication vendor, ip
The concept of softswitch was born
The concept of softswitch originated first in the United States. At that time, in the enterprise network environment, users used Ethernet-based phones to implement the PBX function through a set of Call Control Software Based on PC servers ). For such a set of equipment, the system does not need to separately lay the network, but can achieve unified management and maintenance only through sharing with the LAN, the ov
suitable for a wide range of applications, such as home, corridor, desktop, and IP supermarkets. However, IAD is a terminal device, which is inconvenient for management and maintenance.
Through the Access Gateway AG or the FXO port of the integrated access device IAD, the gateway can communicate with the PBX through the AT0 loop relay. The traditional old-fashioned PBX mostly accesses the softswitch networ
