Configuring the GSU Chapter 11
RADWIN 2000 User Manual Release 2.6.40 11-9
The permitted RFPs are also dependent on channel bandwidth and are color coded as fol-
lows:
There is a further restriction: If there are two distributed sites transmitting to each other,
they must both use the same RFP. This requirement, together with use of shifted transmis-
sion phase (item 3 below), ensures that communicating distributed sites to not interfere
with each other by transmitting simultaneously.
Two GSU managed sites transmitting with shifted transmission phase and using the same
RFP, transmit one half a RFD apart (see Figure 11-3 above).
2. Setting the Tx Transmission Ratio
Since the GSU is always HSM, it must be able to cater for hub site RADWIN 2000 C based
links. (See the RADWIN 2000 User Manual, Chapter 5). If you use asymmetric allocation,
shifted transmission phase becomes unavailable and you cannot “cascade” links as
described in step 1.
3. Choosing the Transmission Phase
Chose the Transmission Phase in accordance with considerations in step 1 above. If you
choose Shifted Phase then the Asymmetric Ratio selector is disabled.
