HI i am configuring ISDN line on cisco 2821....The problem is that even though i get a tone but when i put the line in my router i am seeing my Layer 1 as Deactivited
Kindl see the attached Logs and see if i am doing anything wrong .Moreover the config for the BRi interface are below
ip address 192.168.1.1 255.255.255.252
dialer idle-timeout 2147483
dialer string 00942212121
dialer load-threshold 1 either
isdn switch-type basic-net3
ppp authentication pap callin
ppp pap sent-username abc password 0 acb
Unless the L-1 is Activated, and functional all other attempts to make this work are futile.
I would want to speak with the Telco and or if you happen to have a TA (since its a BRI) would like to check if the phone is working on the ISDN.
