Room faceplate (voice/data):

Faceplates for handicapped-designated rooms are mounted on the wall 48"
above finished floor.

Faceplates for standard rooms are mounted 18" above finished floor.

A positioning strategy for laundry areas, vending machine areas and 
lounges will be determined prior to project commencement.

Faceplates with be mounted with both jacks facing the side of the plate 
so that it provides for the insertion of the data/phone cable from the 
side. (see angle for cable insertion below under project questions)
 
The faceplates/jacks must be approved by SUNY Potsdam prior to project 
commencement and ordering of these components.



IDF/SERs (Wiring closets)

30" free space existsts from the center line to the front and rear for the 
entire height of the equipment rack installed.  The racks are either 6' 
or 3' in height dependent upon the number of data drops (less than 96 data 
drops = 3' rack and more than 96 data drops = 6' rack)



Cat 5 UTP Cabling

No more than 0.5" of conductor should be outside of the cable sheath from 
the end of the Insulation Displacement Contact (IDC).

Cable must not be kinked or deformed during installation.

To avoid electromagnetic interference, all pathways should provide 
clearnances of at least:
  - 4ft. from large motors or transformers
  - 1ft. from conduit and cables used for electrical power distribution.
  - 5in. from flourescent lighting.  Where necessary, parthways should 
    cross perpendicular to flourescent lighting and electrical powercables 
    or conduits.

Feeder raceways in hallways shall be metallic.  Distribution raceways
within the individual room will be securely anchored* to walls in hallways 
and drop locations.  (*see department questions below)

National Electrical Code Adherence - All communications cables are to be 
installed in accordance with Article 800 of the National Electrical Code.



Cat 5 UTP Acceptance Test Procedure

Test results will use the labeling plan described below 
("Faceplate/Cable-Fiber Labeling") and will include the following minimum 
data:

   Cable Type:   
   Cable Model:                 manufacturer's ID
   Velocity of Propagation:     % of speed of light
   Length:                      actual cable length (ft.)
   Attenuation:                 expected vs. actual (dB loss)
   Noise:                       expected vs. actual (mV)
   Resistance:                  expected vs. actual (ohms)
   Wire test:                   expected/actual pinouts at near/far ends
   NEXT:                        expected v.s actual attenuation measured 
                                in dB at specified frequencies - all pairs



Fiber-Optic Cable

The innerduct used for installation of fiber shall contain a pull string.



Fiber-Optic Acceptance Test Procedure

After terminations and splices have been completed, each terminated fiber 
shall have an OTDR trace made as a permanent record of the fiber 
characteristics.  this test shall be performed in both directions at the 
1300 nm wavelength.



Faceplate/Cable-Fiber Labeling


Each room faceplate is marked with a unique identifying number.  Labelling 
will be machine generated and clearly visible.  The exact labeling scheme 
will be determined at time of project commencement and will include items 
such as:

 - room #
 - IDF to which the faceplate is cabled
 - the faceplate #

Buildings with only a signle BDF or IDF will continue with this marking 
plan for consistency and future expansion.

Labeling in the IDF wiring closet will be on an indelible tape and be 
marked with a automated labeling system for all data termination jacks.  
The jack will be labeled in the same manner with teh same number under the 
outlet.

All fiber cable must be labeled with durable tags to uniquely identify 
each separate cable at each end of a conduit, at each end of a passaage 
through a wall or floor, at each corner, and at least every 100' of run.



Other

Project Timeline:
 - Start date will be no later than May 20.
 - Completion of "inside student room" portion of the project will be 
   8/9/96.
 - DEC will develop a project plan during the first two week of project 
   implementation in the form of a Gantt Chart.

Changes in the work:
  - adding/changing/deleting a faceplate (cost, procedure)

DEC responsibilities:
  - assign a Project Manager to this project
  - keep the project area free from accumulation of waste material and 
    rubbish that DEC and subcontractors have generated.

Payment schedule and Warranty:
 - Interim payments and final payment need to be specified
 - What is the defintion of "Project Completion"?
    1. work review meeting
    2. project completion walk-thru
    3. punch list completion
    4. final walk-thru
    5. acceptance and sign-off



Questions for our project team/Peter B. to answer:


1. Fiber strand count from BDF to each IDF.  Are 6 strands enough?

2. It will be the responsibility of SUNY Potsdam to secure each IDF, 
   retrofitting a room with a wall/locking-door as necessary.  Budget for 
   IDF security (per Jerry Beaulieu's specs - how much?

3. Warranty (5-year vs. 10-year)?

4. What cable/fiber test results do we want?

5. Do we want diskette-based results of Cat5 UTP/fiber test?

6. Should we specify how many inches apart the raceways need to be 
   anchored so that we feel they are secured adequately?  And, how they 
   are secured?

7. Faceplates will be mounted with both jacks facing the side of the plate 
   so that it provides for the insertion of the data/phone cable from the 
   side.  Do we want them to come in at a 45-degree angle?

8. Who will be our single point-of-contact for the College (campus project
   manager)?

9. Who will accept and sign-off on the project when it is "completed" 
   (defined above)?

10. Costs above the quote (adds, changes) - who will authorize and how 
    much will be acceptable for our budget (5%?)?

11. What other costs (campus testing equipment, Unix hosts, electronics, 
    Internet access, etc) will be part of the residential network 
    project)?

12. Start/end dates - are they OK with the campus (Horan, etc.)?

13. "As-builts"--is the spec as defined by Bill Todd, OK?
