Description

In order to support ASCI, we need to support transmission on the downlink NCH.

This includes
  • decoding the related commands on Abis RSL
  • reserving one of the SDCCH/4 or SDCCH/8 as NCH (similar to CBCH)
  • transmission of NCH messages in downlink
  • re-transmission of NCH messages at least once per second until call ends (see "ASCI OPTIONS FOR OPERABILITY")
