Testing and Connecting the ScTP Cable
Consideration:
• Before connecting the ScTP cable to the RAU, confirm that it meets TIA/EIA
568-A standard and the TIA/EIA/IS-729 supplement.
To test and connect the ScTP cable:
1. Perform cable testing.
Test results are required for the final As-Built Document.
Cable length:
– Absolute Minimum: 10 m (33 ft)
– Recommended Minimum: 25 m (82 ft)
– Recommended Maximum: 100 m (328 ft)
– Absolute Maximum: 150 m (492 ft)
2. Label the cable and make a note of the designation.
This information is needed when connecting the cable to the Expansion Hub.
3. Connect the cable to the RJ-45 female port on the RAU.
Power is supplied by the Expansion Hub. Because the Expansion Hub is not yet
connected, no LEDs will illuminate.
6.4.1.1 Installing RAUs in a Neutral Host System
When installing both iDEN and cellular systems in parallel, either as dual-band or
neutral host systems, special provision must be taken to assure that the individual
RAUs do not interfere with each other.
The 800 MHz cellular and iDEN RAU’s antennas must be separated by 6 to 8
meters (20 to 26 feet) to assure that the iDEN downlink signals do not interfere
with the cellular uplink signals.
