Site specific equipment connectivity requirements are identified in Appendix 1, along with required features. This requirement will support the installation 24 hours a day/seven days a week/365 days a year (24/7/365).

1.2. Background

Historically, the 38th Contracting Squadron (38 CONS) acquired local TS on behalf of its customer sites using a Government-driven Statement of Work (SOW), which limited the contractor to providing services using legacy systems and equipment. Local TS does not include long-distance or Defense Switching Network (DSN) services, which are beyond the scope of this action. Due to changes in technology, equipment, and processes, it has become evident that the Government should acquire these services in a performance-based manner, consistent with the principles contained in Air Force Instruction (AFI) 63-138 “Acquisition of Services.” These services are considered Information Technology (IT) In Accordance With (IAW) Defense Federal Acquisition Regulation Supplement (DFARS) 239.74 “Telecommunications Services.” The requirement herein represents the site’s performance-based requirements for local “dial-tone” and ancillary services as defined herein. As a part of the new process, the Air Force (AF) encourages the Contractor to identify or suggest improvements to existing TS processes, operating procedures, systems, or applications to the Contracting Officer

(CO).

2. SCOPE

The Contractor shall provide all labor, tools, facilities, materials, and services needed to perform and provide local access to the designated circuit demarcation point(s) identified in Appendix 1 to this PWS. These services shall include any equipment, wiring, or infrastructure to ensure the Contractor’s proposed solution is compatible with the Government’s current infrastructure without additional Government expense.
