Telecommunications Infrastructure Design: RITI, RITS and STDP/TBA Network Dimensioning for a 3-Floor Building

Telecommunications Equipment and Infrastructure: RITI and RITS

Equipment of the RITI and RITS: RTV, TB, ventilation, identification plate, 2 power outlets with earth connection, normal lighting (300 lux) and emergency lighting, protection panel, and earthing system connection.

Cable Ducts and Tubes from the General Services Panel to the RITI or RITS

Insulated cables rated up to 750 V, of 2x6+T mm², in a 32 mm tube or an equivalent section trunking.

Expansion of the RITI and RITS Panel

Must be provisioned at 50%.

Protection Devices in the RITI

General cut-off circuit breaker, RCD, omnipolar circuit breaker for room lighting, another for socket outlets, and another for headend equipment.

RITS Difference

The RITS differs from the RITI because it includes protection for antenna amplifiers.

Space for Companies in the Meter Area

Space for two meters will be provided, with two 32 mm conduits running to each room. Space will also be left for: ICP, general and omnipolar circuit breakers, surge protection devices, RCD, and isolation elements.

Maximum Earth Resistance Value

10 ohm.

Connection Between the RIT Ring and the General Earth Terminal

When not modular, with a 25 mm² flexible conductor, connected to a busbar linked to the building's general earthing system.

Multiple Earths in the Building

If there is more than one earth in the building, these shall be bonded together.

Design and Sizing of the STDP and TBA Network

Design and sizing of the network for Publicly Available Telephone Services (STDP) and Broadband Telecommunications (TBA) for a building of 3 floors with 2 flats per floor.

Wherever possible, include an image to make the explanation clearer.

Data:

• The building's location allows access to all available technologies.
• Each flat has: 1 living room, 3 bedrooms, 1 kitchen and 1 bathroom.
