Interface PRI Primary level refers to the time. This is provided by ISDN, or Integrated Services Digital Network. ISDN provides two basic levels. The first and most common, referred to as BRI, or Basic rate interface. The second is known as the PRI, or Primary Interface level. All of this gives the most voice and data transmission can be sent and received via fiber optic cable.
BRI provides 3 independent channels that can be used for voice or data. PRI is a more powerful way to use 24 threads and private support, making it more zilizolengwa in business or other conditions that require a lot of votes or number of lines of transmission bandwidth.
T1 service really does not care at all, but should be considered as equipment. This type of yarn provides an important way for the services provided by the PRI site. In short, the PRI real service, when the T1 equipment used for delivery.
A T1 line consists of 24 channels, each of which used to serve different purposes. All the fiber can be used to provide a private location 24 by phone, or can all be used for the bandwidth for data networking and Internet connection. Other, 24 channels can be separated and dedicated to voice or data to any combination, such as 12 voice lines and 12 lines of Bandwidth.
When used for bandwidth, each channel can provide data for the 64 Kbps bandwidth T1 lines themselves entirely to provide 1.54 Mbps of data.
The real beauty of the organization is basically a client that leases the T1 line itself. This means that the client is dedicated to this alone, to provide reliable bandwidth network or using the internet altogether. This conflicts with data transfer traditional, where the line is back again and again and used by several users, reducing the quality of relationships. This is known as the exchange process and can greatly reduce the quantity and quality of delivered bandwidth.
