請問cisco 677計時制設定的方式?

小弟買了一台Cisco 677,想把家中的TECOM 1086-B換下來，之前
參考了一些發表過的文章，但是就是無法用軟體撥接的方式，
撥接出去，可以麻煩請用的是計時制而且是用CISCO 677人，
能發表一下內部的設定內容:以下是我的設定內容，使用的是seednet計時制

cbos#set nvram erase
cbos#set interface wan0 maxvcs 2
cbos#set password encrypt disable
cbos#set bridging rfc1483 enabled
cbos#set bridging management enabled
cbos#set int wan0 down
cbos#set int wan0 pay disable
cbos#set int wan0-0 close
cbos#set int wan0-0 vpi 0
cbos#set int wan0-0 vci 34
cbos#set int wan0-0 open
cbos#set int wan0 up
cbos#write
cbos#reboot

之後進入cisco 677下show int wan0可以看到

cbos#show int wan0

但是就是無法用pppoe軟體撥接出去..............:(

試試看
cbos#set int wan0 trellis-coding disable
cbos#set int wan0 retrain
如果還是不行就試試不要用T1.413用g.dmt跟g.lite
cbos#set int wan0 standard g.dmt

經過小弟無意間進到公司裡的小白龜，看到了vci是設定為33，就順便再試了一次
，可以正常使用了，謝謝這裡的朋友提供的意見。
