b.            Series Replaced.  Not applicable.

c.             Directives Rescinded.  Not applicable.

3.            authority/REFERENCES

a.             National Communications System (NCS) Federal Telecommunications Recommendation (FTR), FTR1090-1997:  Commercial Building Telecommunications Cabling Standard.

b.            American National Standards Institute (ANSI)/Telecommunications Industry Association (TIA)/Electronic Industries Alliance (EIA)-568:  Commercial Building Telecommunications Wiring Standard.

c.             ANSI/TIA/EIA-569:  Commercial Building Standard for Telecommunications Pathways and Spaces.

4.            SCOPE

The specifications in this regulation shall be used for all OCIO-ITS and SCA space planning.  The Automated Data Processing (ADP) room standards will be applied to all offices receiving ITS services, including those offices where no ITS staff is co-located.

These specifications define a baseline primarily for SCA field service centers.  The requirements for state, regional, national offices and other organizational units may be unique and may require higher performance or additional space and power.  Deviations from this baseline will be decided on a case by case basis at the time of a major renovation or solicitation of new space.

5.            RESPONSIBLITIES

a.             The Technical Support Division (TSD) Group Manager will:

(1)         Provide oversight for all ADP room cabling and/or wiring installation.

(2)         Verify that all required certifications are received.

b.            The Service Center Leasing Agent will:

(1)         Ensure that the specifications in this Regulation are included in solicitations for offers or lease amendments, as appropriate.

(2)         Keep all certifications as part of the official lease file.

c.             Clearing and Approving Officials:

(1)         The TSD Group Manager will approve all final wiring cable plants before installation begins.

d.            The Infrastructure Operations Division (IOD) Telecommunications Operations Branch (TOB) will: 

(1)         Provide the Group Manager with any needed technical assistance.

6.            COMPUTER ROOM PHYSICAL AND SECURITY REQUIREMENTS

Refer to Departmental Regulation (DR) 3901-001, ITS Space Standards for the physical and security requirements for the computer room.

7.            COMPUTER ROOM ENVIRONMENTAL REQUIRMENTS

When cable consists of multiple runs, the Lessor shall provide cable trays or J-hooks to insure that the cable does not come into contact with the suspended ceiling.

8.            DEDICATED ELECTRICAL CIRCUITS AND OUTLETS FOR ADP EQUIPMENT

a.             Computer Room Circuits.  Provide and install dedicated electrical circuits with isolated grounds in the Computer Room.  Dedicated circuits must be 110 volt, 20-ampere standard three-prong circuits with true earth ground terminated into orange or other uniquely marked (“computer use only”) duplex outlets.  Provide and install duplex outlets for each dedicated electrical circuit in the Computer room.  Dedicated electrical circuits will be used for the telephone systems.  The main electrical panel for the computer/voice (if computer/voice is available) equipment will be properly grounded to meet TIA/EIA and Federal Information Processing Standards (FIPS).

b.            General Office Space Circuits.  Provide dedicated electrical circuits with multiple outlets at designated locations throughout the service center with multiple outlets to accommodate the peripheral equipment (i.e. computer workstations, printers).

c.             Electrical Requirements for Uninterruptible Power Supply (UPS) Circuit.  Critical servers are required to be connected to the UPS.

(1)         Uninterruptible Power Supply (UPS).  Dedicated Circuits will be required for use by UPS.

(2)         Number and Type of Circuits.  There will be a minimum of 2 (two) 120 volt, 30 amp minimum with true ground, terminated into a twisting-lock receptacle.  Each dedicated circuit must have insulated, isolated earth ground; conduit ground is not acceptable.

(3)         Receptacle.  The receptacle will be a NEMA L5-30R twist-locking receptacle.

(4)         Location of the UPS receptacle.  The UPS receptacle will be located in the ADP/Computer room where the Local Area Network (LAN)/Wide Area Network (WAN)/Voice (LWV) cabinet is installed.  The receptacle will be located within a maximum of 4.5 feet from the back of the United States Department of Agriculture (USDA) wiring cabinet.

9.            PLYWOOD

One sheet of ¾ inch 4 x 8 foot plywood shall be vertically mounted on the wall in the Computer Room within 3 feet of an electrical outlet and the wiring cabinet.  The backboard should be attached to the wall using correct mounting hardware and procedures.  If the wall is sheet-rocked, attach the backboard to the studs.  If the wall is concrete, attach the backboard using anchors.  The backboard should be painted with fire retardant paint the same color as the interior walls of the building.  This will be the extended demarcation point and for the installation of phone equipment.

10.        TELEPHONE SYSTEM

A telephone demarcation point (D-mark) must be provided on a type 66S block on the backboard for all telephone lines prior to the move date.  The telephone system will be moved by USDA to a new office and will be installed by USDA technicians during move-in.

11.        DISTRIBUTION CLOSETS AND CABLE PATHWAYS

Facilities requiring multiple distribution points within the building or on multiple floors will comply with ANSI/TIA/EIA-569-B standards.

12.        DATA CABLING/TELECOMMUNICATIONS

a.             General Specifications.  All premise data/telecommunications cabling will comply with TIA/EIA-568-B.  All new installations will use Category 6 cabling, as specified in TIA/EIA-568-B.2-1, or higher.  All cabling will meet local building codes.

b.            Exceptions.  Renovations to buildings which currently comply with TIA/EIA-568-A and contain Category 5 cable and terminations may continue to use Category 5 wiring and terminations as specified in TIA/EIA-568-A.

All substantial additions to, or replacements of, existing wiring should comply with the specifications in 12(a) where possible.

NOTE.  Category 5 wiring is unsuitable for Ethernet speeds above 100 Mb/sec.
