Table 1. CER Size Requirements

(Not less than 2:1 ratio Length to Width)

A-46 Mountain Home AFB, Idaho : Installation Development and Design (ID2) must be 10 ohms or less measured at the grounding point.

10.5.5 Size

Minimum size for a TC is 3 meters by 3.5 meters (10 feet by 12 feet); however specific dimensions could vary depending on the type of facility. Contact Base Civil Engineering for any variances. The TC size should be provided in accordance with (IAW) EIA/TIA- 569, Chapter 7, Table 7.2-1.

10.6 Entrance Facilities

All facilities should have entrance conduit into the CER with the minimum number as indicated in Table

1. One of the ducts requires two 5 cm (2-inch) inner-ducts, and one of the ducts requires four 2.5 cm (1-inch) inner-ducts; the rest are spare. If the general area where the new facility will be located is served by a manhole (MH) and duct system, or if the impact of the new facility will greatly develop the area, then a new MH/duct system should be designed to connect the facility to the existing MH/duct system.

See the referenced USAF/LEE letter for additional guidance. For projects where an extensive new MH/ duct system will be required, it is critical that the appropriate E&I agency be consulted as soon as possible in the design definition process.

10.7 Wiring

10.7.1 Voice

All voice wiring should meet the minimum EIA/TIA Category 5 requirements.

Consult with the base CSO for outlet type requirements such as RJ-11 vs. RJ-45 jacks for voices and whether there are any special keying or wiring requirements. The voice riser cable from the CER to each TC should be sized at a minimum of 30% of the total pair distribution planned for the TC rounded up to the next 100 pair count. The riser conduit design should include spare capacity for a second riser cable of equal size.

10.7.2 Data

All copper data wiring should meet the minimum EIA/TIA Category 5 requirements.

All fiber cabling should meet the minimum ANSI/EIA/TIA/492AAA requirements.

Installed length of copper data cables must be less than 90 meters (295 feet). The minimum size fiber optic riser cable from the CER to each TC is 6 strands. Coordinate with the base CSO for additional requirements.

The riser conduit design should include spare capacity for a second fiber optic cable of equal size.

10.7.3 Outlets

The design should provide for an outlet box and wiring to support two voice, two data, and future fiber optic cable outlets every 9.3 square meters (100 square feet) of usable floor space. The designer should coordinate outlet requirements with the base CSO. In areas where conduits are used, the minimum size to serve a single outlet box should be 2.5 cm (1-inch) diameter to allow installation of copper and fiber optic cable. Pinouts for the voice and data jacks will conform to the EIA/ TIA 568A standard.

10.7.4 Secure Wiring

All secure communications requirements should be wired IAW AFSSI 30-30, and AFSSM 70-11.

The figure shown on this page, extracted from EIA/TIA-569 Figure 2.2-1 Intrabuilding Elements, illustrates the typical relationships between the major telecommunications pathway and elements within a building.

All Undergournd cable shall be installed in 51-mm (2-inch) conduit.
