Hi,

I have got CISCO 1721 and I am facing problem to bring up 2nd ISDN
channel on this router. On this router I was suspecting IOS problem
hence I upgraded the IOS from 12.2(13)T to 12.2(13)T9 but it seems
by upgrading IOS didn't resolved this problem at all I have
checked ISDN link, which is fine. I tried changing the value of
threshold "dialer load-threshold 100 either". I have kept this value
100 and then I doing extended ping with 1500 bytes from Ethernet to
Ethernet but 2nd channel is not coming up at all, but if I decrease
threshold value to 5 or 10 then 2nd channel comes up straightway. Can
anyone tell me how to resolve this problem?

interface Dialer2
description backup-isdn
bandwidth 64
ip address negotiated
encapsulation ppp
no ip split-horizon
dialer pool 2
dialer idle-timeout 0 either
dialer string ***********
dialer hold-queue 10
dialer load-threshold 5 either
dialer persistent
dialer-group 1
no peer default ip address
no cdp enable
ppp authentication chap pap callin
ppp chap hostname *****
ppp chap password *********
ppp pap sent-username ******** password ********
ppp multilink

Sounds like it is working as designed. The load in this case is an 8-bit
representation (0-255) of the 5 minute input or ourput rate (you can change
the 5 minutes using the "load-interval" command.

If you set it to 100, the load would have to be 100/255 * 64000 = 25kb/s for
about 5 minutes before the second link came up.

Sounds like you may want to reduce "load-interval" if you want the link to
spring up faster.

This doesn't seems to be working on any of this IOS's (12.2(13)T to
12.2(13)T9) I have tried with all the permutation and combinations by
reducing the timings but problem appears to be continue (I have tried
this on around 5 different locations)

Any other suggestions ?
