2.1. Structured Cabling System
2.1.1. General Information
The Structured Cabling System (SCS) is the telecommunications infrastructure of the local area network that is intended for the transmission of digital, voice and video information and the provision of other telecommunications services.
The building features special premises to accommodate the main switching center (MCC) of the complex of information and computer systems as well as special premises to accommodate switching floor centers (SFC) of low-voltage systems.
The architectural and construction solutions of the building envisage vertical cable shafts that make it possible to lay the necessary volume of cables between the floors, taking into account the reserve capacity of the sleeves. Cable shafts are equipped with cable trays, a lockable door, and are limited to personnel access.
The final number and location of the automated workstations where computers and/or telephones are to be installed will be specified in the course of the detailed design and agreed upon with the Customer. At the stage of the project documentation it is intended to install automated workstations in accordance with the plans for the location of terminal equipment.
2.1.2. General requirements for the SCS design
The technical means of the SCS subsystem ensure:
- information exchange;
- Possibility to separate and optimize information flows;
-reliability of data and multimedia information transfer.
When designing the SCS complex it is assumed to use "Telegartner" equipment from Germany.
SCS of the building is designed with the use of modern network technologies.
SCS is designed in accordance with ISO/IEC 11801 (international) standards, as well as in consistence with existing requirements of regulatory and expert state bodies and departments of the Russian Federation (see the list of regulatory documents).
When performing SCS design work, the design solutions for cable runs, embedded connections and workplace equipment, as well as the design solutions for bringing in external information trunks of the building shall be taken into account.
2.1.3. Requirements for the composition and structure of the SCS
The purpose of the work is to build a cable system serving for data transmission and multifunctional information, and including the following subsystems:
- vertical cabling subsystem;
- horizontal cabling subsystem;
- The main communication center of the building (MCC);
- distribution points of the building floors (floor cross-connections of low-voltage systems (LVC) or communication niches).
Structured Cabling System (hereinafter - SCS) under construction complies with category 6 or higher.
The manufacturer must have a certified ISO 9001-2001 (ISO 9001:2000) quality management system.
Components of the cable infrastructure are patch panels and sockets for connecting terminal equipment. Patch panels and active network equipment have a standard 19 ' boarding size for placement in telecommunication cabinets. CCs are equipped with 19-inch installation double-frame racks of dimensions not less than 600x600 height to 42U. If necessary, the use of wall-mounted racks is possible. Racks will be equipped with accessories necessary for functioning, such as cable organizers, socket blocks.
Fittings embedded designed to provide cable bending with a radius of at least 25 mm, which meets the requirements of ANSI / TIA / EIA-568-B.2., EN50174 and ISO / IEC 11801.
To reduce the cost of SCS is supposed to use modular sockets and patch panels, ie for these components used the same type of information module RJ-45.
SCS will be equipped with the required number of patch cords of different lengths to perform switching at the distribution points and connect the terminal equipment at the stage of working design.
SCS envisaged by the project covers the following functional areas of the building:
- Rooms and service / administrative areas of the hotel apartment type;
- Administrative offices for building management services and security/maintenance services;
- Technical rooms where communication with the public address areas is necessary;
- Public areas, conference room area and other areas not intended for rental (if available).
- Receptions.
For the areas to be rented out, SCS is not provided. The main SCS cable system on the floors of the building intended for lease assumes the laying of a single-mode fiber-optic cable to each of the floors to enable unimpeded provision of the service delivery transport environment to the provider chosen by the tenant. For laying in the CC floors it is assumed to use a fiber-optic cable with a capacity of 8 wires.
2.1.4. Requirements to the backbone cable subsystem
SCS vertical cabling subsystem provides connection of the SCS to the SCS floor switching centers (SCs) by single-mode fiber-optic cable with 8 core capacity.
Vertical SCS cable subsystem is supposed to be laid in special dedicated cable channels (embedded pipes and cable trays).
The vertical cabling subsystem ensures data transmission at the speed of no less than 10 Gbit/s.
It is assumed that optical or copper (depending on the type of PBX selected at the detailed design stage) vertical communication lines connecting the GSC premises with the ATC equipment located in it (line crossing), and cross equipment of the floor distribution points will be arranged. For the telephone system of the building it is possible to use multipair cables of the 5th category as vertical cable lines.
2.1.5. Requirements for the horizontal cable subsystem
The horizontal SCS horizontal cabling subsystem provides the connection of terminal equipment of the various infrastructure systems of the Facility to the switching centers (CC) of the floors. Horizontal cabling subsystem is designed using twisted pair cable of category 6 or higher and provides for transmission of data along any path between equipment and network stations at a speed of at least 100 Mbit/s. At the workplaces of the personnel equipped with SCS is supposed to install a modular socket containing two RJ-45 ports for the connection of an automated workstation and telephone equipment. According to the requirements of ISO / IEC 11801 length of cables of horizontal subsystem from the server or from the cross cabinet to the workplace shall not exceed 90 meters.
Horizontal cabling subsystem SCS mounted in the corridors - in trays behind the false ceiling in the working and living space covertly - in plastic PVC pipes.
Horizontal cabling for the leased premises is not provided by this project and shall be performed by the tenants after the premises of the complex are put into operation.
2.1.6. Requirements for SCS switching centers
The SCS Communications Center provides for open two-frame 19" telecommunication racks for the installation of the patch panels, cable management and active equipment systems. The requirement for restricting unauthorized access in this case is achieved by locking and equipping the SCS room itself with access control system elements due to the small size of the room. Active equipment of the local area network (LAN), if necessary, will be located in the cabinets and racks of the SCS and floor SCS. In the room SCC expects to install standard enclosed telecommunication cabinets at least 800x800 42U or more in case the appropriate size of the switching space, providing installation of the required number of active and passive switching equipment will not provide a reserve of at least 25% of the calculated.
2.1.7. Requirements for workstation equipment
Socket blocks will be installed at the typical workplaces. Each block contains two RJ-45 sockets, one of which is designed to connect a personal computer, the second - to connect a telephone set. Cable separation schemes are unified and provide a guaranteed connection to the cable system of LAN equipment and telephone equipment (personal computers, network printers, servers, other computer equipment that has standard interfaces for connecting to local computer networks, as well as digital and analog telephones).
The project provides workstations for the following functional areas:
- Administrative hotel rooms: 1 workplace at 6 m.s.;
- Administrative rooms of operation service: 1 workplace for 8 sq.m;
