Pager Does Not Receive Pages or Receives From the Wrong Transmitter
The Where aRe yoU (WRU) transmission is broadcast across the network so that it is
independent of the IP address of the target RF-B! transmitter controller. In order to get a page
the RF-C! controller must be able to unicast directly to the IP address of the RF-B! transmitter
controller.
• Cause 1:
The tables in the network router and/or RF-B! transmitter controller that associate the IP
and MAC (Ethernet) address are corrupted or RIP is turned off. Reset the RF-B!
transmitter controller to force an ARP request. If this doesn’t work reset the router to
reload the configuration.
• Cause 2:
The IP address of the RF-B! transmitter controller is wrong or the RF-C! controller
configuration has the wrong IP address associated with the color code for the target
transmitter.
• Cause 3:
If there is heavy congestion at the transmitter under test, the RF-C! controller has the
option to pick an alternate route through another transmitter.
• Cause 4:
The PMU memory is full or there is an overflow condition. This can be verified without
actually seeing the PMU by running the RF-A! receiver trace. The first word of the WRU
response will indicate this condition.
Voice Quality Diagnostics
The information that follows will aid in determining the cause of potential voice quality
problems.
The pages crackle
The crackling sound is due to clipping. The following are known to cause this problem.
• The pager may be too close to transmitter. Move away from the antenna.
• The peak to average parameters are incorrect (RFO FIPS command: r/w 1100-1109).
Perform a DIP switch 2 reset to properly default the parameters.
