Technical Requirements -
T/D Cabling Design Guide
Purpose
This Guideline is intended as a template to assist VBA personnel in specifying the
requirements of a telephone and data Cabling Distribution System (CDS)
appropriate to the needs of a typical Regional Office. This Guideline adheres to the
precepts of structured cable design and so calls out related regulations, standards,
and specifications.
Proper application of this Guideline will result in procurement specifications which
lead to the design and installation of a properly structured CDS which is flexible,
expandable to allow for future network expansion or changing office configurations,
and capable of the bandwidths associated with contemporary telephone and data
cable networks. This Guideline will also result in a CDS that is easy to administer.
1. Typical VBA Network Hardware
The installed CDS will connect:
Distributed PC Workstations, Printers, Servers
Distributed Fax, Telephone and Modems, EPABX
Local Area Network (LAN) Hubs / Switches / Routers
In a LAN conforming to IEEE 802.3 Ethernet 100 Base-T, 100 Base-F,
and 100 Base-TX standards.
2. Applicable Regulations, Standards, And Specifications
The Contractor shall provide the CDS in accordance with the following
regulations, standards, and specifications.
