How to configure dialer map ip and dialer pool simultaniously

Hi everybody,

for out of band management i want to add a new dialer interface on my ISDN router.

The actual configuration shows like this:

interface Serial0:15
...

encapsulation ppp
dialer rotary-group 1
dialer-group 1

...

interface Serial1:15
...

encapsulation ppp
  dialer rotary-group 1
  dialer-group 1

...

interface Serial2:15
...

encapsulation ppp
  dialer rotary-group 1
  dialer-group 1

...

interface Dialer1
description configuration for rotary-group1
ip unnumbered Loopback0
  encapsulation ppp
dialer in-band
dialer map ip 172.16.1.1 name ABC1 class rueckruf 010110

dialer map ip 172.16.1.2 name ABC2 class rueckruf 010111

...                                                                                               ! at least 250 dialer maps in dialer1

dialer map ip 172.16.1.192 name ABC192 class rueckruf 010192

Adding a new dialer results in error message "no free dialer".

As far as I know, there is no chance except to change my physical interfaces from rotary-group to "dialer pool-member". But I need all physical interfaces for the dialer maps (90 B-Channels). In my configuration, this results in 251 dialer interfaces.

Is there any chance to mix up this configuration in a better way ?

The dialer I want to add looks like this:

interface Dialer251
description Out-of-Band Management for Routers to configure
ip address 10.11.1.1 255.255.255.252
encapsulation ppp
dialer remote-name newrouter
dialer string 012345
dialer pool 1
dialer-group 1
ppp authentication chap
ppp chap hostname myname
ppp chap password mypassword
ppp multilink

Thany you in advance

Michael
