測試的環境是3745加一個支持，vwic-2mft-g703的nm-2w,對于這模塊和卡，37的所有ios版本都支持。

測試打環用得線纜：一跟普通的直通的雙絞線，rj45的水晶頭（rj45與rj48的區別實現其中的線序不同而已），一根型號為cab-adpt-75-120的線纜，具體看圖示。

首先啟動router，nm-2w的en燈亮，正常，router已經監測到nm-2w，不過這下還不能確定nm是否完全沒問題，等到load ios后，過十秒的樣子，g703的卡al亮紅燈，正常，然后把直通線與cab-adpt-75-120的接口對上底下為圖

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(這個根據solt/inter:0),封裝pp no shut，把線纜插上去，顯示紅綠燈都亮，一會兒正常的是紅燈滅，就綠燈亮，在看debug ppp packet信息。。。。。。。e1保持up狀態，不過s1/0:0為一個物理up，鏈路down,這個為正常現象。有些有毛病的模塊一回兒e1 up  一會兒down，中間記得模塊要插緊。e1 down的時候亮紅燈，up的話亮綠燈
