▀ How HNB-GW Works
 The HNB-GW is reloaded or service restarted and SCCP Subsystem Number (SSN) allowed from CN
(SGSN/MSC) node is received.
 The received SSN Prohibited or Point-code Address Inaccessible indication comes for a CN node, HNB-GW
start a configurable timer.
 If SSN allowed indication comes before timer expires, the timer is stopped.
 On timer expiry HNB-GW deletes all SCCP connections towards the CN node.
 If SSN Allowed indication comes after timer expiry, HNB-GW sends RANAP-RESET command
The RANAP-RESET from HNB-GW is sent only if HNB-GW-initiated RANAP-RESET is configured in HNB-GW
service.
