Meaning
Receive Modulation
Mode
The modulation mode currently being used on the receive channel.
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.
Receive Modulation
Mode Detail
The receive modulation mode in use. For a list of values and their
meanings, see
Range
The range between the PTP 670 Series ODUs. This is displayed in
kilometers by default, but can be changed to miles by updating the
Distance Units attribute to imperial, as described in
Table 198 Receive Modulation Mode Detail values and meanings
Value
Meaning
Running At Maximum Receive
Mode
The link is operating at maximum modulation mode in
this channel and maximum throughput has been
obtained.
Running At User-Configured Max
Modulation Mode
The maximum modulation mode has been capped by
the user and the link is operating at this cap.
Restricted Because Installation Is
Armed
The Installation Wizard has been run and the unit is
armed, forcing the link to operate in the lowest
modulation mode. To remove this restriction, re-run the
Installation Wizard to disarm the unit.
Restricted Because Of Byte Errors
On The Wireless Link
The receiver has detected data errors on the radio and
reduced the modulation mode accordingly. The radio
may achieve a higher modulation mode as shown by the
vector error, but there is some other error source,
probably RF interference.
Restricted Because Channel Change
Is In Progress
This is a transient event where the modulation mode is
temporarily reduced during a channel change.
Limited By The Wireless Conditions
The radio is running at the maximum achievable
modulation mode given the current wireless conditions
shown by the vector error. The radio is capable of
reaching a higher modulation mode if wireless
conditions (vector error) improve.
