Description of Bulletin:

The purpose of this Bulletin is to provide Qwest-approved COE installation Service Suppliers with the requirements necessary to provide correctly-depicted office arrangements upon completion of installed work. It is the responsibility of the Service Supplier to provide to the Design Engineer, with an accurate portrayal of all changes of new, existing and modified central office condtions. This Bulletin in designed to clarify some of the basic guidelines required for both engineering and installation marked prints and to serve as an addendum to Qwest Technical Publication 77353, Standard Configurations and Technical Reference documents.

Central Office (CO) records issued through the Central Office Equipment -
Facility Management (COE-FM) system allow remote engineering of new/existing telecommunications equipment and provide Qwest with an ongoing inventory of existing equipment arrangements. Marked CO prints, when adding, removing or modifying equipment, provides engineering instructions for both internal and external Installation forces of varying experience levels. These marked prints enable accurate record keeping, adherence to Qwest standards, document compliance with federal, state, and local requirements, and satisfy Qwest's corporate requirement to maintain records for insurance/asset management purposes.

Notes.

  • The "Note" information contained in this document is not intended to be all inclusive. Additional notes may be required to cover other similar information. Notes should consist of similar formatting and information.

Definition

  • The Note "X." used later in this document indicates a note number and corresponding note that must be included on the associated note layer (see above). For example:

Note "X." / [SYM] / DEFINITION OF USE AND/OR PART INFORMATION.
  • Brackets [ ] used within a note indicates variable information that needs to be included. Text within the brackets indicates the type of information usually required. See "Floor Plan" for example.
  • Installation Quality Bulletin 11-01 Disclaimer Note:Text that is formatted in a tablur and shaded format to clarify a point (e.g.,“Examples,”is for informational purposes only and is not intended to be a direct depiction of an actual COE-FM office drawing “Table.”

Floor Plan

Dimensions

  • Framework end guards (EG) and spacers (SPCR) shall be identified within the end guard or spacer symbol (Refer to Figure 1) with the appropriate dimension and designation similar to what's illustrated below. All other dimensions shall depict office conditions.

Figure 1

  • Text identifying dimensions within end guards and spacers shall use text height point one (.1) placed on equipment dimensions layer 36.Note:Text that is placed in a vertical fashion shall read from bottom to top (TP 77353, Sec 3, Part B, 3.02)
  • Front aisle markers ( ) indicate the front aisle between adjacent facing lineups. The direction the marker points does not have any significance but should be oriented to point "up"on horizontal depicted lineups, and pointed “right”on vertically depicted lineups.
  • Guard rail adapters shall be indicated as illustrated above.
  • Dimensions in symbol brackets [x-x] shall not be used for locating purposes. These dimensions represent an approximate dimension that should remain after measuring the appropriate dimension. In the example above the [4-2 9/16] dimension is what should be remaining after measuring from the left wall 25 feet 10 9/16 inches.
  • Dimensions are measured from the equipment bay uprights (sides) or from guard rail to guard rail including guard rail extensions. Front aisle measurements are from front guard rail to front guard rail including guard rail extensions. Do not dimension from end guards or spacers.

Lineup Numbering:

  • All new lineups will follow the current standard frame numbering scheme documented in Qwest Technical Publications. Note: The first bay in a lineup is .01 not .00.
  • Frame/cabinet numbering for new lineups must consist of a unique four-digit number (indicates a specific lineup of equipment in a CO), a decimal point, and then a two-digit consecutive number (indicates a specific frame/cabinet within an equipment lineup). For example: 0101.01, 0101.02, 0101.03…
  • Existing frame/cabinet numbering schemes within a lineup must be consistent and to its' logical end.
  • Lineup numbering does not continue across a main or egress type aisle. For example, if a lineup where across an aisle from 0101.20 it would not be 0101.21, it would have a different lineup number starting with .01.
  • Utilizing an Odd/Even alternating lineup number scheme is not permitted for new CO areas or lineups unless the ultimate number of lineups on a floor will exceed 99.

Stanchions:

  • Framework stanchions are required at the "beginning" or "end" of framework lineups where a light switch for equipment task lighting is necessary. Note:Equipment lineups less than 15 feet in length do not require light switches at both ends. A switch would normally be located on the non-growth end.
  • Standard Qwest column stanchions(Refer to Figure 2) will be located on the COE-FM Equipment Floor Plan Layer 31. The column stanchion template is located with the Floor Plan templates. Stanchion dimensions shown below are for reference:

Figure 2

  • Electronic Switching System (ESS) compartment cableway stanchions will remain on the Low Cable Plan drawing. All other types of existing or relocated stanchions (pipe or column) can remain on the Floor Plan drawing.
  • The removal of a stanchion symbol is required when replaced by a framework or bay occupying the same floor space.Note: The stanchion symbol may be relocated if the stanchion will be moved to a new location.

Cable Plan

  • A default size 20" wide cable rack is provided in most cable rack Configurations, however, the required cable rack width will need to be determined per the following factors;

  • Width of aisle
/
  • Type of equipment in lineup

  • Length of lineup
/
  • Heat dissipation of equipment

  • Cable rack cable capacity
/
  • Obstructions limiting vertical capacity

  • Alpha numeric exhibit numbers (reference TP 77351) will be used to indicate cable rack support and assembly fabrications on the HIGH & LOW CBL plans per TP77353, Section V, Part C, 27.03, Note 18
  • Example: TP77351, Chapter 6A, Exhibits 2-E1-66 and 2-E2-66A are represented on a Drawing by respectively.
  • Refer to TP 77351 for additional exhibits.
  • Cable brackets used to support cables (see Grounding Cables) from cable rack or auxiliary framing shall be identified and indicated on the appropriate Cable Rack Drawing(Refer to Figure 3 and Example A). Note:Each unique bracket support will require anote identifyinmg a different symbol, part number, etc.Cable brackets represent a type of cable support and shall be shown on the cable rack layer 57(HIGH CBL) and/or layer 62 (LOW CBL) even if supported from auxiliary framing, u-channel, etc.
