ISDN CHAP MPP between Cisco3662 and lucent/ascend Max1800 ou P50

[bidouille]

Cisco 3662 is connect to PRA
Max1800 or Pipeline 50 is connect to BRI

Pipeline 50 or Max 1800 is calling Cisco 3662
I try to make a MPP CHAP connection over more than 1 B-chanel (ISDN).

The first B-channel goes up . everithing fine

BUT
The second B-channel never goes up

On the Cisco,with the 'debug isdn event' I don't see any trace from P50 or Max 1800 trying to open second B-channel.

Somebody can help me ?

Thanks

Check your load threadhold level on calling party. 2nd bri will only come up if ther are traffic more than load threadhold.

Thanks for your response
The Load is 100 FTP Transfert at 7.1 kb/s

on the lucent the parameter configuring the load is TargetUtily : 70 % of bandwith.

Normaly it shoud open the next B-channel !

I don't understand ...
