Bandwidths in Network: It is very likely that there will be several different channel
bandwidths in a given network. Table 45 gives a list of bandwidth combinations that permit
synchroni
zation without gross loss of efficiency. Depending on the channel bandwidth size,
only subsets of Table 45 will be shown in the config
uration wizard screen.

All Masters Collocated: The network needs to be configured differently depending on
whether all masters for which interference can potentially occur are collocated or whether
interference needs to be considered for masters which are not collocated. Answer “Yes” to
this question if master to master interference only occurs between collocated masters,
otherwise answer “No”. If “No” is selected, the maximum distance between masters which
can potentially interfere is required. This is the subject of the next bullet.
Master to Master Distance: This is only displayed (see Figure 154) if All Masters Collocated
is
set to “No”. In this case, the longest distance over which two masters can interfere must be
entered here. Maximum distance is 200 km (120 miles).
Slave Interfere: Select “No” if there is no potential of a slave interfering with another slave.
Select “Yes” if there is potential for one slave to interfere with another slave. If the option
“Yes” is selected, then the maximum distance between slaves which can potentially interfere
is required. This is the subject of the next bullet.
Slave to Slave Distance: This is only displayed (see Figure 154) if Slave Interference is set
to “Yes”. In this case, the longe
st distance over which two slaves can interfere must be
entered here. Maximum distance is 200 km (120 miles).
