中心端一条E1线 路由器为7200，模块使用PA-MC-2E1/120
通过frame-relay连接10多个分点
是使用信道化还是非信道化好 ？
下面为我按两种方式初略的配置，请大家指教：

非信道：
controller E1 #/0
unframed
framing no-crc4
linecode ami
cable 120
no shutdown

int s0/0:0
enca fr

这里该这样配置各分点的连接 有子端口（如int s0/0:0.1)吗？


信道化

controller E1 #/0
no unframed
framing no-crc4
linecode ami
cable 120
no shutdown

channel-group 1 timeslots 1-15,17
channel-group 2 timeslots 18
channel-group 3 timeslots 19
channel-group 4 timeslots 20
channel-group 5 timeslots 21

这样行吗？
