测试的环境是3745加一个支持，vwic-2mft-g703的nm-2w,对于这模块和卡，37的所有ios版本都支持。

测试打环用得线缆：一跟普通的直通的双绞线，rj45的水晶头（rj45与rj48的区别实现其中的线序不同而已），一根型号为cab-adpt-75-120的线缆，具体看图示。

首先启动router，nm-2w的en灯亮，正常，router已经监测到nm-2w，不过这下还不能确定nm是否完全没问题，等到load ios后，过十秒的样子，g703的卡al亮红灯，正常，然后把直通线与cab-adpt-75-120的接口对上底下为图

然后在ios中配置e1,通道化行，非通道化也行，然后在inter s1/0:0(这个根据solt/inter:0),封装pp no shut，把线缆插上去，显示红绿灯都亮，一会儿正常的是红灯灭，就绿灯亮，在看debug ppp packet信息。。。。。。。e1保持up状态，不过s1/0:0为一个物理up，链路down,这个为正常现象。有些有毛病的模块一回儿e1 up  一会儿down，中间记得模块要插紧。e1 down的时候亮红灯，up的话亮绿灯
