Attenuation

Attenuation is the measure of signal loss in the cable segment.

Near-End Crosstalk (NEXT) loss

NEXT loss is a measure of signal coupling from one wire pair to another within a single

UTP cable segment.

3.8.4.5 Labeling

Cabling shall be identified with a standardized, double-ended system to facilitate cable

and equipment connection identification. (Refer to ANSI/TIA/EIA-606 for more

information.) The label should show the following:

• Equipment identification for each end of cable.

• Connector reference designator for each end of cable.

• Direction along the cable where terminating equipment is located.

• Floor and room of the equipment.

In general, the following considerations need to be observed in implementing a labeling

system:

• Labeling shall indicate the destination ends of the cable, in terms of equipment name

and connector reference designator or name. This applies to connectorized, lugged,

or punched-down cable terminations, regardless of the application (RF, audio, or

control).

• Labeling shall be imprinted on white opaque material (preferably plastic or plasticized

paper) using indelible black ink.

• Labeling should wrap entirely around the cable. It should be secure enough to assure

label retention if the cable is to be pulled through conduit.

• Label placement shall be between 10 and 16 cm (4 and 6 in.) from each end of the

cable (or the most logical point that would allow the label to be easily read).

• Information printed on each label should be brief but clearly understandable.

Because of limited space, abbreviations and acronyms should be used. If

abbreviations are used, they should be industry standard.

• All cables shall be properly labeled by the manufacturer as to the type, capacity, and

approval ratings of the cable.

3.9 Main Rack Configuration

The main rack typically contains the BCU and one ACU of the RadioFrame System. The

rack must be an standard 19” EIA-compliant rack, or equivalent.
