CPOS和E1的配置

想请高手帮忙确认一下CPOS和E1的配置有没有问题!
组网情况是这样的:
NE20上的CPOS划分出4个E1静通道捆帮成一个组,通过SDH传输设备,到AR46-20的4E1-F模块捆绑成的一个组,不知道我的配置有没有存在什么问题?谢谢!

经过确认没有问题！
需要注意的问题还有:

华为设备的CPOS时隙映射可能跟SDH传输设备的时隙映射不一样.

就像上面的配置,我捆绑的是1,2,3,4四个通道,可是能经过SDH传输设备对接起来的

只有1,4通道.在检查SDH设备无果的情况下,

我把63个E1都 划了出来,结果发现22,和43通道起来了

原来映射关系是这样的

华为 <----> SDH
1     <---->  1
22   <---->  2
43   <---->  3
4     <---->  4

因为我只捆绑了四个通道 ,目前知道的也就这些.
