GSM未接通代碼解釋：
1 Normal class
1.1 Cause No. 1 "unassigned (unallocated) number"（未分配的號(hào)碼）
This cause indicates that the destination requested by the mobile station cannot be reached because, although the number is in a valid format, it is not currently assigned (allocated).
1.2 Cause No. 3 "no route to destination"（目的地?zé)o路由）
This cause indicates that the called user cannot be reached because the network through which the call has been routed does not serve the destination desired.
1.3 Cause No. 6 "channel unacceptable"（信道無法接受）
This cause indicates the channel most recently identified is not acceptable to the sending entity for use in this call.
1.4 Cause No. 8 "operator determined barring"（操作者定義禁止）
This cause indicates that the MS has tried to access a service that the MS's network operator or service provider is not prepared to allow.
1.5 Cause No.16 "normal call clearing"（正常的呼叫清除）
This cause indicates that the call is being cleared because one of the users involved in the call has requested that the call be cleared.
Under normal situations, the source of this cause is not the network.
