  [[OSMO_ETWS_CMD]]
  ==== Osmocom ETWS Command
  
  This message is sent by the BSC to transfer the ETWS Primary Notification (PN)
  from BSC to BTS and enable/disable transmission of ETWS PN by the BTS.  For more
  information about ETWS, see 3GPP TS 23.041.
  
  If the ETWS PN length is > 0, the BTS will immediately start transmission
  of the received ETWS PN on the PCH using P1 Rest Octets.  It will also forward
  he ETWS PN to the PCU to enable the PCU to transmit it via PACCH on active TBF.
  
  If the ETWS PN length is 0, the BTS will stop any ETWS PN broadcast via the PCH.
  
  The Channel Number IE is set to the Downlink CCCH (PCH).
