ISDN PRI E1 Backup - Only brings up 1 channel

We have a new configuration in place that isn`t quite working properly. When failing over to the ISDN E1 from a serial lie, only one channel is brought up. I enclose what I believe to be the appropriate bits of config as I think it is likely a config error as I want to bring all available chnnels up. Not quite sure where to go with this one so help would be appreciated

controller E1 1/0

pri-group timeslots 1-16

interface Serial1/0:15

no ip address

encapsulation ppp

dialer pool-member 1 min-link 14

isdn switch-type primary-net5

Re: ISDN PRI E1 Backup - Only brings up 1 channel

You can force more channels to come up by using "ppp multilink links minimum":

http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123cgcr/dial_r/dia_n1g.htm#wp1158197

This will force the router to try to keep this number of links up at all times. If you are on usage-based billing, you should be looking at the "dialer load-threshold", as stated earlier.
