A.正确
B.错误
[多选题]xGW GGSN割接上线前，需要检查PDP最大空闲时间（idle-time）设置，下面说法正确的是（）。
Before xGW GGSN cutover, need to check the PDP idle-time configuration, which statements are correct?
A.固定设置成1000MIN。
Idle-time should fix to 1000 min.
B.如果新建xGW GGSN是为了替换我司V3 GGSN，则要求xGW的idle-time设置和V3 GGSN保持一致。
If the new GGSN is for replacing ZTE old V3 GGSN, then idle-time value should be same with old V3 GGSN.
C.如果不是替换我司V3 GGSN，则要求和局方现网设置保持一致。
If the new GGSN isn't for replacing ZTE old V3 GGSN, then idle-time value should be same with current network.
