Cabling 
All components of the RFS are connected using standard CAT 5 cabling installed 
in existing raceways or conduits when available. Use only RJ45 (T568B) 
connectors for system components. The same is true for connecting the RFS to 
the iDEN Interface and the Customer LAN. 
If using a patch panel between RFS components, ensure the following: 
• 
Use only a CAT 5e- or CAT 6-rated patch panel. 
• 
Follow all TIA 568B standards. 
• 
Total impedance, end to end, cannot exceed 8 ohms. 
• 
Use only CAT 5e or CAT 6 wiring. 
 
Maximum length between RFS components shall not exceed 328’ (100 meters).  
A Universal Repeater Unit (URU) can be installed to extend the distance 
between any two RFS components to 656’ (200 meters).  
Up to 2 URUs can be used between any two RFS components to extend the 
distance to 984’ (300 meters). 
The maximum DC resistance allowed cannot exceed 26.2 Ohms per 1000 feet. 
Use plenum rated cable if the cable traverses through a plenum (open air) space. 
The proper installation of computer network cabling is critical to the safe and 
reliable operation of the computer network. It is recommended that standards 
developed by the Telecommunications Industry Association/Electronic Industries 
Association (TIA/EIA) and the Canadian equivalent (or equivalent standards in 
other countries) be followed. Applicable NFPA codes, local electrical codes, local 
building codes and other standards in this manual shall also 
be 
conformed to 
when installing computer network cabling. 
NOTE:  It is recommended that a specialist in the installation of computer 
networks perform computer network cable installations. The 
specialist 
should 
have the expertise, knowledge of applicable local codes, and the test equipment 
required for a quality installation.
