UNREACHABLE • The termination is unreachable.
• This occurs when MGW KEEPALIVE declares an MGW unreachable.
• This changes to ACTIVE when MGW KEEPALIVE detects an MGW is
reachable or any termination previously UNREACHABLE starts sending
MGCP messages (NTFY, RSIP).
FAULTY
• The termination returneda permanent error code, making it unusable for
future calls.
Note The error code may occur only in certain circumstances
and re-audit/auto-recovery may succeed. This does not
mean the termination recovered from that condition.
• The flag MGCP-MAX-FAULT-COUNT controls how many times BTS
tries to recover the fault (performing re-audit/auto-recovery) before
putting it in this state.
MTRANS
• Maintenance Transient, the termination is in the middle of
anaudit/re-audit/auto-recovery.
• This state may go along with other states (MTRANS-UNREACH).
IDLE The termination is not involved in transient/active call
BUSY
• The termination is involved in Active/Transient call.
• This state may go along with CTRANS state.
CTRANS
• Call Transient, the termination is involved in a Transient call.
• This state always goes with BUSY.
RESERVED The termination is reserved for a call during Busy Line Verification
SERV_EFFC_TEST The termination is in a Service Effecting Network loopback or Network
Continuity test.
DOWN This occurs when the MGW sends an RSIP down (graceful) message.
