Suspended ceiling support rods and wires may be used as a means of support for
computer network cabling if used in conjunction with appropriate cable fasteners. Refer to
ANSI/TIA/EIA-569-A and CSA-T530 for more information.
CAT-5 cables shall not be laid directly on the tiles of a false ceiling. Refer to
ANSI/TIA/EIA-569-A and CSA-T530 for more information.
CAT-5 cables shall not be run from one building to another building. If the computer
network needs to
be extended to another building, a specific cabling system shall be
engineered. Options for extending from one building to another may include the use of
fiber optic cable or a T1/E1. Computer network cabling entering and/or leaving a building
shall be properly grounded and protected from surges as required elsewhere in this
document.
3.8.4.4 Testing
Every effort should be made to ensure a quality installation of the computer network
cabling system. Even the best installation effort cannot guarantee a properly working
system. It is therefore required that a computer network cabling system be tested for
proper performance.
The procedures and specifications in the TIA/EIA Telecommunications System Bulletin
(TSB) 67 shall be used for this testing. TSB 67 has four primary parameters to test.
Below is an overview of the four test parameters needed to assure a properly working
system.
Wire map
The wire map test is used to verify wire pair to pin termination at each end of the cable
and to check for installation connectivity errors. It is recommended that 100% of cables
be tested using a testing tool such as Microtest® Microscanner™ Pro. (Be sure the tester
can check for a “split pair” configuration).
Each of the 8 conductors in the cable are tested for:
• Conductor continuity to the remote end of the cable
• Shorts between any two or more conductors in the cable
• Crossed pairs in the cable
• Reversed pairs in the cable
• Split pairs in the cable
• Any other wiring errors in the cable
Length
The length test is used to determine the maximum physical length of the cable segments.
The Microscanner™ Pro and many other models can be used to check cable length,
which are accurate within a few feet. The RFN guideline for cable length is 100 meters
(approximately 328’ for less).
