Link Capacity: The maximum aggregate data rate capacity available for user traffic,
assuming the units have been connected using Gigabit Ethernet. The link capacity is variable
and depends of the prevailing wireless conditions as well as the distance (range) between the
two wireless units..
Transmit Modulation Mode: The modulation mode currently being used on the transmit
channel. List of all the modulation modes can be found in Section 16 "Data Rate Calculations"
where data rate calculations plots are given for each available modulation mode..
Receive Modulation Mode: The modulation mode currently being used on the receive
channel. List of all the modulation modes can be found in Section 16 "Data Rate Calculations"
where data rate calculations plots are given for each available modulation mode.
Link Symmetry: The Link Symmetry control setting, expressed as a ratio of the number of
OFDM symbols in each TDD frame where the first number represents the transmit direction
and the second number represents the receive direction.
NOTE: If Link Symmetry is set to "2 to 1" at the master ODU, it will be displayed as "1 to 2" in
the Status Page of the slave ODU, indicating that the master-slave direction has double the
capacity of the slave-master direction.
Receive Modulation Mode Detail: This supplies the user with information regarding the
receive modulation mode in use. Possible values are:
x
Running at maximum receive mode
x
Running at user-configured Max Modulation Mode
x
Restricted due to byte errors on the wireless link or local Ethernet Tx Fifo Drops
x
Restricted because a DFS channel change is in progress
x
Restricted due to telecoms acquisition mode
x
Restricted due to the low Ethernet link speed
x
Limited by the wireless conditions
Range: The range between the 600 Series bridge ODUs. The PTP 600 Series Bridge
displays range in km by default, but if the user would prefer to display range using Miles, the
'Distance Units' attribute should be set to imperial, as described in Section 8.3.15
"Properties".
