Compatible Systems 5.4 ユーザーズマニュアル

v Note:  While the shorter header can enhance performance slightly, routers 
from other vendors may not be compatible with this feature.

This checkbox allows the router to use echo packets on each of the physical 
ports in the bundle to determine whether individual links are up. If one link 
in a bundle goes down, the router can divert data away from that port.

v Note: If the primary port goes down, the entire link will go down, even if 
MPQual is enabled. If left unchecked, any individual link in the bundle can 
bring down the entire multilink. (Parameters for echo packets are configured 
in the PPP Options/PPP Link Quality dialog box.)

WAN Chat Script Editor Dialog Box

You can access the Chat Script Editor Dialog Box by selecting Global/WAN 
Chat Scripts in the Device View. 

Compatible Systems routers support standard communications chat scripts 
that let you specify dialing and/or connect sequences between this router and 
remote routers or terminal servers.
