 Completed the SCS design of the structured cabling system of the business center in St. Petersburg

 DESIGNING SCS

This project documentation for a structured cable system (SCS) in the building of the Administrative and Business Complex, located at: St. Petersburg, is made on the basis of documents :

• Private technical assignment

• CONTRACT

• Architectural and construction drawings and layouts of furniture arrangement;

• Regulatory and technical documents.

  The main purpose of the SCS is to create a common "cable space" and switching elements for building the infrastructure of the building's information system, which allows users to exchange data for analog and digital telecommunication applications.

   

  The composition of the SCS PROJECT 

1. SCS consists of the following subsystems:

• horizontal subsystem;

• workplace subsystem;

• trunk subsystem;

• the main cross of the building;

• SCS premises GKK (server oversized equipment);

• main cable entries;

• SKS server room - 1;

  Horizontal subsystem SCS

1. The horizontal subsystem is a cross-over floor in the cross room of the floor (KKE) and cable lines from it to the information ports of the current or adjacent floor.

   Horizontal subsystem SCS (except SCS for WLAN access points) is based on the Systimax GigaSPEED XL solution (unshielded twisted pair UTP 4x2 cat.6).

   The SCS horizontal subsystem for WLAN access points is based on the Systimax GigaSPEED X10D solution (unshielded twisted-pair UTP 4x2 cat.6A).

   For typical office premises with a raised floor, the information ports of the horizontal subsystem are located at consolidation points (TK) under the raised floor.

   TCs are placed in such a way that circles with a radius of 4m around each TC cover all office space, with the exception of places where there is a different way of placing information ports.

   The number of information ports for office premises is calculated by the formula: N = 1.2 x 3 x S / 6, where S = area of the room (m2).

   The cross fields of the horizontal subsystem are located in the open switching racks manufactured byConteg . For the factory of cables in the switching racks and for laying patch cords, double-sided vertical organizers are provided. Active equipment KKE is located in the telecommunications cabinets manufactured by Conteg with a height of 42U and a size of 800x1200 mm.

   Number of cabinets in KKE - 2 pcs.

   Cabinets have a closed cooling architecture and IP55 protection class.

   The cross-connects of the horizontal subsystem with active network equipment are made according to the cross-connect scheme:

• Active LAN network equipment is connected via patch cords with an RJ 45 connector on one end. Non-terminated patch cord ends are sewn onto Systimax PatchMax 360 patch panels.

• The SKTS active equipment is connected via 25-pair cables with a Telco connector on one end. Non-terminated cable ends are sewn onto Systimax PatchMax 360 patch panels - one pair for each port (1st pair in the port) of the panel. Two Telco 25 x 2 cables are connected to one 48-port panel. The layout is as follows:

A pair with a purple-gray color coding remains unconnected. 

Copper cables of the horizontal subsystem are embroidered on the panel Systimax PatchMax 360. Type of ports - RJ-45.

Cross fields in CCEs are based on the Systimax imVision intelligent solution.

The length of the cable line from the horizontal cross to the information port at the workplace should not exceed 90m.

Workplace subsystem

1. The workplace subsystem includes sockets with information ports of the horizontal subsystem and patch cords used to connect user equipment (computers, telephone sets, printers, fax machines, etc.) to information ports.

   The number and location of workplaces, places of peripheral devices that need to connect to the SCS is determined on the basis of furniture plans.

   For workplaces in typical office premises with a raised floor, information ports are led to the desktop using patch cords with RJ-45 connectors at both ends (embroidered according to the T568B standard) included in the consolidation point under the raised floor and removed from the raised floor via cable output .

   In typical office premises with a raised floor in places where peripheral devices are installed that require connection to the SCS, and in meeting rooms floor hatches are installed with information ports connected to the consolidation point under the raised floor by patch cords with RJ-45 connectors at one end (embroidered according to standard T568B). Non-terminated patch cord ends are sewn onto modules of information ports in floor hatches.

   In office premises with a missing raised floor, information ports are placed in wall outlets, boxes or floor hatches with pre-assembled embedded pipes.

   In certain premises, the information ports are connected directly to the cross-country cross-country in the ECC, bypassing the consolidation points.

   Trunk Subsystem

2. The main subsystem is designed for communication between the main cross-room (GKK), cross-rooms of the floors (KKE), the server room SK-1 and the main cable entries (GKV-1, GKV-2).

   The trunk subsystem in the optical segment is based on the Systimax LazrSPEED (MM 50/125 optical cable) and Systimax TeraSPEED (SM 9/125 optical cable) solutions.

   The trunk subsystem in the copper segment is based on Systimax GigaSPEED XL (UTP Cat. 6 copper cable), Systimax GigaSPEED X10D (UTP Cat. 6A copper cable) and Systimax PowerSum (UTP multi-pair copper cable 5e) solutions.

   The trunk subsystem is performed in a star-type topology with the main cross in the SCC building.

   Multi-pair copper cables of the trunk subsystem are embroidered on the Systimax VisiPatch 360 panel (2UTP cables 25 x 2 per panel) according to the following scheme:

 The four-pair copper cables of the trunk subsystem are sewn onto Systimax PatchMax 360 panels. The port type is RJ-45.

The optical cables of the trunk subsystem are terminated on the Systimax 360G2 optical shelves. Port type - LC duplex.

The cross fields of the backbone subsystem are based on the Systimax imVision intelligent solution, with the exception of the cross fields on the Systimax VisiPatch panels.

Connection scheme of active network LAN equipment to passive equipment of the backbone subsystem - inter - connect .

The connection scheme of active network equipment SKTS to the passive equipment of the backbone subsystem is cross-connect.

The type of crossover connecting lines - VisiPatch 360. Installation in the GKK - cabinet MA- 02, installation in the GKV-1 - cabinet E 1-03, installation in the GKV-2 - cabinet E 2-03.

The SKTS equipment is connected to the GKK and the crossover link of the connecting lines is carried out using RJ 45- VisiPatch 360 patch cords (manufactured at the facility or at the facility).
