Hi there,
i have here some old 3640, that was running before with an old isdn multiplexer for a dialin solution.
Due to that only a few users use this dialin, the expensive isdn multiplexer is no longer needed and now a 4 Port BRI Card is inside.
The problem is actually, that the isdn dialin works but not the dialin for analog users (via the digital modems)
System and IOS:

Really old stuff but it should still work.
Is the modem module still in slot 3?
Lines configured like below?
line 97-114
! --- This must match the group-range in the Group-Async Interface
! --- Use the show line command to determine which lines are to be configured for dialin
autoselect during-login
autoselect ppp
modem Dialin
Please check the rest of the prerequisites listed in the link:
regards,
Leo

Hi Leo,
the lines are matching with the lines specified in the Async intfce. as you can see below.
line 97 114
script modem-off-hook offhook
script callback callback
modem autoconfigure type mica
exec-character-bits 8
special-character-bits 8
transport preferred none
no ip tcp input-coalesce-threshold
autoselect during-login
autoselect ppp
hold-character 0
i added in the actual config the "modem dialin" command to the lines 97 114.
Let's see if this helps.
Cheers

Hi,
I have the same problem - how did you resolve that issue?

Hi,
the problem was never solved.
The BRI was not able to speak with the digital modem card/module, maybe there was some problem with the eeprom software version on the BRI.
