Histogram Data - Motorola PTP 500 Series User Manual

Receive Modulation Mode
The modulation mode currently being used on the receive channel. A list of all the modulation
modes can be found in Section 12 "Data Rate Calculations", where data rate calculations
plots are given for each available modulation mode.
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 "3 to 1" at the master ODU, then the slave ODU will be set
automatically as "1 to 3". 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 PTP 500 Series bridge ODUs. The range is automatically set during
installation. Range is displayed 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
7.14 "Properties".

7.3.1 Histogram Data

The histogram is calculated over a one hour period. If the equipment has been running for
less than one hour, then the histogram is calculated over the current elapsed time. The data
used to compute the histogram statistics can be downloaded in an ASCII comma separated
value (CSV) format via the diagnostics CSV Download page, see Section 7.11.2 "CSV
Download".
