The process is as follows:
1. ZXG10-OB06 (V1.0) gives the BSC an indication that one multi-frame-
mode L2 link has been established on the wireless path.
2. During the paging, GSM 04.08 message PAGING RESPONSE contained
in DL_EST_IND sent to FURRM module.
3. After the FURRM module sends the EST IND message, there may be
two situations:
• If the current channel is the TCH activated in the service mode, the
synchronization timer enables to wait for the synchronization
between CHP and TC.
• If the synchronization is not implemented until the timer expires,
the FURRM sends the CONN FAIL IND message to the BSC. This
message instructs BSC to wait for OB06 to release the channel
where the conversation cannot be established normally.
