GPS Sync Pulse Status
This field indicates the status of synchronization as follows:
• Generating sync indicates that the module is set to generate the sync pulse.
• Receiving Sync indicates that the module is set to receive a sync pulse from an outside source
and is receiving the pulse.
• ERROR: No Sync Pulse indicates that the module is set to receive a sync pulse from an
outside source and is not receiving the pulse.
NOTE:
When this message is displayed, the AP transmitter is turned
off to avoid self-interference within the system.
Max Registered SM Count
This field displays the largest number of SMs that have been simultaneously registered in the AP
since it was last rebooted. This count can provide some insight into sector history and provide
comparison between current and maximum SM counts at a glance.
Data Slots Down
This field indicates the number of frame slots that are designated for use by data traffic in the
downlink (sent from the AP to the SM). The AP calculates the number of data slots based on the
Max Range, Downlink Data, and (reserved) Control Slots configured by the operator. See Max
Range on Page 249 and Downlink Data on Page 250.
A + in this field (for example, 28+) indicates that there are additional bit times that the scheduler
can take advantage of for internal system communication, but not enough for a full data slot.
Data Slots Up
This field indicates the number of frame slots that are designated for use by data traffic in the
uplink (sent from the SM to the AP). The AP calculates the number of data slots based on the Max
Range, Downlink Data, and (reserved) Control Slots configured by the operator. See Max Range
on Page 249 and Downlink Data on Page 250.
A + in this field (for example, 9+) indicates that there are additional bit times that the scheduler
can take advantage of for control slots (which are half the size of data slots), but not enough for a
full data slot.
