Introduction The Connecticut State Colleges & Universities (CSCU) has adopted the ANSI/TIA

(American National Standards Institute, Telecommunications Industry Association)

Standards and BICSI (Building Industry Consulting Service International) practices regarding the installation of structured cabling systems constructed with a minimum of

Category 6 compliant components. Liberal reference to these standards and practices are made throughout this document, and the Colleges/Universities are encouraged to consult the original documents for more detailed information on wiring standards. This document is intended to summarize and highlight significant aspects of these standards and practices for the purpose of creating a simplified reference which

Colleges/Universities may use in the planning, bid preparation, and implementation of a

Structured Cabling System for their campus.

Each College/University is expected to adhere to the elements identified in this document for the implementation of any new wiring projects. Compliance with these standards will result in model installations which are easy to administer and modify when necessary, and which will in turn guarantee optimal performance from the network.

These standards are intended to allow CSCU to meet the telecommunications requirements of the Colleges and Universities for the next 15-20 years. It is essential that CSCU Network Management shall be consulted prior to and throughout the planning and design process to ensure that present and future voice and data service requirements can be met.

CSCU Information Technology (IT) Management MUST provide prior written approval for any deviations from these standards, or CSCU will not assume financial responsibility to upgrade the facility to performance expectations. Where ambiguity or questions arise to specific details not mentioned in these standards, appropriate TIA, NEC, and BICSI standards shall apply.

All applicable building codes must be strictly adhered to in regards to telecommunications services. CSCU cannot authorize variations to any building codes.

In situations where a variance to a building code is required, the request for a variance must be submitted in writing to OSBI (Office of State Building Inspector) and local building officials, and only implemented if approved in written by the AHJ (Authority

Having Jurisdiction).

The use of a Commissioning Agent for the Telecommunications infrastructure is allowed, but is not required. A manufacturer’s system warranty is required for all projects unless otherwise instructed by CSCU.
