IBM Advanced Connectivity System (IBM ACS) Bronze Line Installed
in Bulgarian Saving Bank in Gabrovo branch - Bulgaria
The project is realized in 2000.
Introduction
In May 2000 EDA Ltd. signed a subcontract with NetIs Ltd.,
which designs the cabling system for installation of IBM ACS
Bronze Line in Bulgarian Saving Bank in Gabrovo branch.
The IBM Advanced Connectivity System (IBM ACS) is a high tech cabling solution
providing protocol independent cabling infrastructure, flexibility for use and easy
expandability.
IBM arranged the products in their cabling system into four families since year 2000:
- Gold: Category 7 solutions/Class F (draft);
- Silver: Category 6 solutions/Class E (draft);
- Bronze: Category 5 solutions/Class D;
- Crystal: Fiber Optic Solutions.
Each family has a different level of performance and all products in the family
exceed the performance requirements of the ISO/IEC, CENELEC and TIA/EIA standards relevant
to that family.
Topology of the System
For building distributors, which consist of wiring closet,
we have used rack enclosures exceed the DIN - IP 54 standard. Racks
have glass doors with accessories for mounting of 19 inches.
Horizontal subsystem consists of cables that start from the floor
distributors and end to the individual outlets. We have implemented
the cable traces in white plastic ducts from UNEX - Spain.
The cabling system consists of 86 workplaces.
Each workplace has one double outlet that supplies:
- one phone connection and one LAN connection;
- or two LAN connections;
Wiring Closet
We have installed a horizontal subsystem on every floor depending
on the architecture of the building. All connections for every floor start
from an equipment rack containing patch panels, patch cables and the active
LAN equipment (hubs). Racks are with dimensions
37U - two pieces.
Cable Traces
The cable traces are implemented with cable ducts. We have used
plastic ducts from UNEX - Spain, with dimensions from (16x30)mm to
(60x80)mm. The cable traces start from the wiring closet and end to each
data/phone outlet.
Cables
We have used an installation cable (between the wiring closet and
the outlets) of type IBM P/N 59G1092, S/FTP (shielded foiled twisted pair),
4 pairs, category 5, halogen-free version. This cable is certified for
frequencies up to 100 MHz and is produced from IBM.
For connecting the hubs and the workstations to the cabling system
we have used patch cables type S/FTP, 4 pairs, category 5, flexible,
halogen-free version, 1, 2 or 3 m.
Outlets
We have used 86 white universal outlets "on the wall" version for
Series 78 of UNEX MiniTrunking subsystem.
LAN Equipment
We have used three Dual Speed Hub 500 24-port hubs from 3Com SuperStack II
family. The SuperStack® II family of hubs continues the tremendous success
of SuperStack II enterprise networking solutions. Offering the high quality,
reliability, and robustness of the 3Com SuperStack II family in a shared
media device, a SuperStack II hub gives you a flexible, cost-effective
connectivity solution for your enterprise network.
The Dual Speed Hub 500
10/100 Autosensing on Every Port
Autosensing 10/100 Mbps per port offers full compatibility with
Ethernet and Fast Ethernet devices. The ports automatically detect the
speed of the attached device and direct the data to the appropriate
repeater segment.
Smart Autosensing
Smart autosensing ensures that both speed and cable quality are
automatically sensed to maximize performance. The Smart autosensing 10/100
Mbps feature enabled by the management module enhances the standard
autosensing feature by recognizing not only the cable speed (10 or 100 Mbps),
but also the cable quality (incorrectly/correctly installed Category 3, 4,
or 5 cable) and maximizes the throughput. Once enabled by the user, Smart
autosensing allows you to forget about the cable category issues because
the hub determines the optimal setting.
Distance Extender Modules
The optional 100BASE-TX and 100BASE-FX distance extender modules
significantly expand the configuration capabilities of the SuperStack II
Dual Speed Hub 500. These slide-in modules overcome the Fast Ethernet
Class I and Class II repeater and cabling distance restrictions that
handicap existing network configurations. They allow you to connect the
hub to any Fast Ethernet device or daisy-chain a virtually unlimited
number of hubs over distances up to 100 meters over copper wire or up
to 2 kilometers (in full-duplex mode) over fiber optic cable.
Modular Management
The optional slide-in module provides full SNMP support, as
well as a number of advanced automated capabilities to make your life easier.
