i have bri connectivity which is configured using dialer. the configuration is given below. according to the configuration second bri channel should go up when there more data transfer. that is working fine. the problem is when ther is less data transfer. the channel waits till the idle time out period. channel two goes down .at the same time channel one also goes down and comes up.at this moment i am able to ping my remote router .but i am not able to ping from my pc . i get four request time outs what is the reson for this. the config is given below
