PANNING SUBSCRIBER TERMINALS
The Service Interface Unit should be panned to assure optimum performance of
the ST. If problems are encountered, check that the installation guidelines in
DLP-001 are not breached. All results must be entered on the Commissioning
Test Result Sheet, see DLP 015.
STEP PROCEDURE
1. Panning Pole Mounted Antenna
1. Place and tighten a tie wrap immediately underneath the pole bracket to prevent
the assembly sliding down the pole.
2. Loosen the antenna fixing bolts sufficient to allow the antenna to rotate around
the pole.
3. Point the Antenna in the general direction of the Central Terminal Antenna
4. Using the DVM, measure the DC voltage between Ground and Receive Signal
Strength Indicator (RSSI) Monitoring on the Antenna (see Figure 65). The
voltage measured is a relative indication of the received signal strength; The
lower the voltage the weaker the RX signal, and vice versa. A reading of
1.4volts or greater indicates a viable link.
5. Whilst observing the voltage on the DVM, pan the Antenna through the peak
point, then pan back to it.
6. Using a 10mm spanner or socket torque the pivot bolts to 12Nm.
7. Place the strain relief strap around the drop cable and pole and strap to the pole
ensuring that the 70mm minimum bend radius of the cable is not exceeded.
