Configuration via SMS
Q: Can the DSPbR be configured using SMS messaging?
A: No. This feature is not available in Baseline 1.0.
Modules
General
Removing and inserting RFBE and RFFE modules into the respective slots when the DSPbR is “on”.
Q: What will happen if either an RFFE and/or RFBE is removed or re-inserted whilst the DSPbR is on?
A: The RFFE’s and RFBE’s are designed to be removed and inserted whilst the DSPbR is “on”, hence the term
“Hot Swappable”. Once inserted the module will communicate with the controller and establish its identity. The
CSC will then auto configure the new or replaced module based on the previous module’s configuration if it is
the same type of module and same slot.
Q: What will happen if either the DSP or Ref Gen + Aux modules are unplugged and re-inserted?
A: When you unplug the Ref Gen + Aux module, the system will lose reference and go into stand-by and then
go back live when you plug the Ref Gen + Aux back in. Similarly, when you unplug the DSP module the system
will go quiet and resume normal operation about a minute after you have the DSP module back in.
RFFE
Q: Can an RFFE module be configured for a single band / single board only?
A: Yes. Simply installing only one side, Side “A”, of the RFBE module with a single band RFFE board will
provide functionality for either a single uplink or downlink band or in rare cases provide both up and downlink
RX paths through the same board.
Q: Can Uplink and Downlink RFFE boards in different bands be paired within the same RFFE module?
A: Yes, this is possible, however providing a back-to-back BPFM’s is more the challenge and therefore this
option is not currently available.
RFBE
Q: Can an RFBE module be configured for a single channel?
A: Yes. Simply installing only one side, Side “A”, of the RFBE module with a single channel RFBE board. Side
“B” will be void of a channel. The disadvantage of this is should you wish to increase the number of repeated
channels in the future, either the RFBE module it returned to factory for retrofit of the second RFBE board into
Side “B” or a second module with both sides populated is purchased and installed. The second more
economical approach is to install a module with both sides installed and disable the second channel, leaving it
as a back-up channel.
Q: Can uplink and downlink RFBE boards be paired within the same module?
