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”
whe
re 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”
whe
re data rate calculations plots are given for each available modulation mode.
Link Symmetry: Link Symmetry: A ratio that expresses the division between transmit and
receive time in the TDD frame. The first number in the ratio represents the time allowed for
the transmit direction and the second number represents the time allowed for the receive
direction.
NOTE: Link Symmetry is configured at the master ODU only. The appropriate matching Link
Symmetry is set at the slave ODU automatically. For example, if Link Symmetry is configured
as “2 to 1” at the master ODU, then the slave ODU will be set automatically as “1 to 2”. In this
example, 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:
Running at maximum receive mode
Running at user-configured Max Modulation Mode
Restricted due to byte errors on the wireless link or local Ethernet Tx Fifo Drops
Restricted because a DFS channel change is in progress
Restricted due to telecoms acquisition mode
Restricted due to the low Ethernet link speed
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
