Essential ICT Services and Infrastructure Guidelines

List of Essential ICT Services

1. List the services that must be provided in the new ICT and indicates which are mandatory and which are optional. Solution:

• Service radio and television (RTV): capture, adapt and distribute radio and television signals that reach the building, so they can be interpreted by the user receivers.
• Telephone service available to the public (STDP): providing access to telephone and data transmission through the basic telephone network (TB) or integrated services digital network (ISDN).
• Service broadband telecommunications: to provide access to telecommunications services broadband (television, data, etc.), cable (TBA) or a wireless (SAI), promoting the development of the Digital Home.

2. Description of the Common Area of ICT. Solution:

Once the tubes are inside the building, the outer pipe is called channeling link, because it connects the networks of service providers with the ICT (Fig. 1.7 of the book). This pipeline starts at the general point of entrance of the building and extends to where telecommunications enclosures are installed.

• The telephone and cable television usually arrive via underground. Use the link below pipeline, located in the basement of the building and connected to the valve box outside.
• Radio and terrestrial or satellite television usually receive by air. So they enter the building by channeling upper link, located on the roof or the roof.

3. Indication of Network Pipe Names.

• Distribution Network
• Mains
• Network user inside
• Dispersion network

4. Conditions for Using RITU.

In small installations, the upper and lower enclosures can be replaced by one, which will house the equipment of all services received. This enclosure must be located in the lower area of the property, where would the RITI. It can be installed in houses and buildings up to three floors and ground floor, and a maximum of ten user access points (PAU).

5. Installation of Channeling Link with Gutters.

To mount with gutters channeling link below, we will need four separate spaces. As each channel has two, to mount the installation two chutes are needed. Each space will have a minimum useful cross-section, which is calculated from the following expression: Si≥ C · Sj Where Si = inside surface of the channel space. C = 2 for coaxial cables, or C = 1.82 for other cables. Sj = Sum of the sections of the cables housed. As used three coaxial cables 10 mm2 each, the necessary section in each space will be: Si ≥ C · Sj = 2 · 30 mm2 = 60 mm2

6. Installation of Tubes in a Building.

According to the standard of ICT, in channeling lower link must use the same number of tubes that exist in the outer pipe. Therefore, five tubes must be installed. as the number of user access points is between 21 and 40. The use that will be given to the tubes is as follows: 3 for telephony and broadband services (TBA + STDP). 2 reserve. The measures of the tubes depend on the number of cables, and be defined in the project. In any case, they must be 40 and 63 mm in diameter.
