某个小区下2G作为被叫，全部提示无法接通，请教高手原因；

此小区下手机作为被叫，无法被寻呼到，所以网络侧disconnect,原因值为27，cause-value:destination-out-of-order (27)
LOG和ts24.008中的解释如下，我们是通过重启小区解决了问题。

Cause No. 27 "destination out of order"

This cause indicates that the destination indicated by the mobile station cannot be reached because the interface to the destination is not functioning correctly. The term "not functioning correctly" indicates that a signalling message was unable to be delivered to the remote user; e.g., a physical layer or data link layer failure at the remote user, user equipment off-line, etc.
