  2. T1, T3, and SONET Networks.

    Advantages of T1 Each T1 is equivalent to 24 separate circuits between two sites, an advantage for T1 because multiple lines and multiple-site networks are expensive and hard to manage. The end-user equipment at each site can be PBXs, videoconferencing systems, imaging systems, or host computers. T1s connecting two PBXs are called tie trunks. For some old PBXs that cannot directly receive a T1 signal, a T1 line must first be terminated at a channel bank. Analog lines are subject to noise and signal deterioration, and equipment that is used for reconstructing the analog signal cannot make them suitable for data transmission, because analog lines amplify both original signal and noise.

The surge protection will stop computer components being damaged due to a spike on the national grid, and the UPS will take over if there is a power cut. The UPS can provide power to the servers in the computer centre for a considerable amount of time. The smaller servers all have a small UPS, and these are configured to shut the server down if the power is off for any longer than 10 minutes.
