2. Space permitting, a minimum of 8' by 8' plywood for MDFs; 4' by 8' plywood for IDFs.
3. Backboards will be mounted vertically.

1. 110 Termination blocks will be placed on the backboard with the horizontal center line 48" AFF. 110 Termination block placement will follow the format detailed on Attachment F. Deviation from the centerline placement will be permitted only to accommodate growth.
2. If the free space is from 24" AFF to 96" AFF, the centerline is placed equidistant (or 60" AFF) to accommodate vertical growth of both voice and data.
3. 110 Termination blocks will be placed on the backboard left to right.
4. Spare locations on the backboard will be marked to ease future equipment installation. No other arrangements (such as underground or riser in the center) will be allowed unless agreed to by the UIS consultant.

1. A 110 termination for all RJ21x's will be placed on the backboard by the wiring contractor.
2. The 110 block will have a 25-pair cable terminated and the other end run to the RJ21X and terminated on an anphinal connector and connected to the Verizon block.

1. Standard station wiring is two separate sheathes of 4-pair solid copper twisted pair 24 gauge.

   39. For new construction, both voice and data horizontal cabling should utilized Category 6 horizontal cable for the distribution of communications, plenum. Avaya P/N 2071E-004XXX. Transmission performance specification for the proposed 4 pair 100 ohm Category 6 cabling for shall be TIA/EIA 569-B.2-1. Voice cabling should be white in color and data cabling should be blue in color.

   40. For renovations, both voice and data horizontal cabling should be Category 5e horizontal cable utilized for the distribution of communications, plenum rated, Avaya P/N 2061-004XXX and should meet or exceed Category 5e Link performance outlined in the latest revision (568-B.1). Voice cabling should be white in color and data cabling should be blue in color.

2. All station wiring runs will be home runs. No other intermediate distribution points will be used.

3. Maximun station runs is to be 250'.

4. Shielding may be installed at an extra charge where electrical isolation is required. (It is not technically possible to provide all Network services over shielded wire.)

5. Teflon or Plenum covering should be used.

6. Station wiring will be brought to the AVAYA 110 Termination blocks for voice and AVAYA patch panels for data as follows:
   
   

   • Voice wiring: run horizontally along the top of the backboard and down the center of the area reserved for the specific station's termination block.
     
     
   • Data wiring: run vertically along the front edge of the backboard and then horizontally along the bottom of the backboard to the center of the area reserved for the DATA patch panels for that station location.
     
     
   • Data patch panels may also be terminated on a standard 19 inch rack.
     
     
7. 110 C-4 clips are used for station termination.
8. Raising the board off the wall using 2 by 3's and running the wire behind is acceptable and preferred where possible.
9. Station termination blocks will be spaced to accommodate the station cable serving the existing number of locations.
10. A 18A Distribution Ring will used between 110 columns (ID 104-049-382)
11. AVAYA 188 wire troughs (for voice and data) will be mounted across the plywood frame between the VOICE and DATA blocks. Cross-wire will run down and through the 188 wire troughs for VOICE and up and through for DATA. All cross-wire will be supported in 188 wire troughs.
12. Station wire will be installed to transmit high-speed data as either ISDN digitized voice and data or standard data (for example; Ethernet or Token Ring applications).
13. Station wiring will not be installed near fluorescent lamps, high-voltage sources, electrical motors, or other sources of interference.
14. Splices in the cable plant are not acceptable because they compromise the integrity of the inside wiring for high-speed data transmission.
15. All cables run in ceilings for horizontal distribution must be bundled together and supported from the floor above or the building structure inside the ceiling. They can not be supported by the ceiling, ceiling hangers, or other utilities in the ceiling and must not lie on the ceiling.
16. Telepoles may be approved by the Harvard consultant in some cases.
17. Unterminated wire drops from ceilings or exposed wiring along ceilings are not acceptable.
18. NEVER use staples to install telecommunications cabling.

1. Station wiring must be concealed for safety and aesthetic reasons. The preferred concealment method is to fish the walls.
2. Conduit, cable trays and raceways (wire mold) are acceptable alternatives depending on the situation.
3. Raceways (wire mold): if raceways are used, plastic raceways will be installed in individual offices containing one or two jacks. Metal raceways will be installed in open areas, large rooms, multiple jack locations, and hallways.
4. Conduit, cable trays and raceways (wire mold) will be installed in accordance with building and electrical codes.
5. The UIS project manager will participate in sizing and design decisions.

1. Composition
   Composed of 24 gauge ARMM Cat. 3, twisted pair cable.
   
   • Sizing
     Riser cable pairs should be six (6) times the number of stations to allow for the recommended 50% growth per station.
   • Installation
     Standard installation method is to run the riser cable in conduit or floor sleeving. The cable will be terminated at the Intermediate Distribution Frame (IDF) and the Main Distribution Frame (MDF) on 110 blocks. Riser cable will be home run from the IDF to the MDF. There will be no additional junction points between the IDF and the MDF.
   • Administration
     Process of documenting work performed during and after the installation of the riser system. Requirements include labeling the voice riser pairs in the basement as well as at the IDF location with the station jack ID numbers.
   • Cross-connects
     110 C-4 clips are used for station termination in IDF's and the MDF. They are also used to terminate riser cables, with the exception of the last clip in each row. The last clip in a row terminates with a 110 C-5 clip. This clip covers the 25th pair of the riser even though it will not be cross-wired.
   • All stations must be cross-connected to the riser system. Six (6) stations will be cross-wired per 25 pair row. The 25th pair will not be cross-connected. Each station location on the station block should be identical to the station location on the riser block.
     Station labeling will be carried through to the MDF.
     Data Riser System (stations more than 250 feet from data equipment or building with IDF's)
     The following Data Riser specifications apply only if the stations served by the riser cable are more than 250 feet from the data equipment
   • Composition
     Composed of a 12-strand 62.5 multi-mode and 10/125 um 12 strand single mode fiber riser rated cable, installed in innerduct, home run from the IDF to the MDF.
     All strands must be terminated on patch panels at both ends. Multimode terminated with a silver or chrome colored connector and the singlemode with a black colored (Siecor TER-156) connector.
   • Sizing
     The recommended fiber size is 12/12 strands.
   • Installation
     Contractors will leave service loops at both ends of the fiber by the contractor when installation is complete. Fiber will be installed within innerduct, and will be home run from the individual IDFs back to the MDF.
   • Administration
     
     
   Fiber optic cable will be labeled at the MDF area with the floor where the fiber originated and appropriate station information (labeling will be the same as the IDF).
