TTY and async configuration

[tgif]

I'm trying to configure a dial-in service on a 3640, it has 4 BRI ports on slot 2. When I issue "group-range 65 68" the error message "No physical hardware support for 65" comes up.
My async config is as follows :

interface Group-Async1
ip unnumbered Loopback0
no ip directed-broadcast
encapsulation ppp
async mode interactive
peer default ip address pool default
ppp authentication pap radius
group-range ?????????

Using the line command I get "No physical hardware support for 65"

Any help or suggestions will be greatly appreciated.

Thanks

The group-range command defines the member asynchronous interfaces in the interface group.


interface group-async 1
 group-range 1 16
 encapsulation ppp
 ppp authentication ms-chap dialins
line 1 16
 autoselect ppp
 autoselect during-login
 login authentication admins
 modem dialin

I forgot to add this part to the last response

Define the group range of the interface. The number you use with the group-range command depends on the number of modems you have in your access server. That is, if your access server has 48 modems, you have 48 asynchronous interfaces. For 48 modems and a T1 card, issue the group-range 1 48 command.

Thanks for the info, however when I enter the group-range command I get the following error -

Router(config-if)#group-range 1 4
No physical hardware support for 1

On running diag I get the following -

Slot 2:
BRI (S/T) port adapter, 4 ports
Port adapter is analyzed
Port adapter insertion time unknown
Hardware revision 1.0 Board revision A0
Serial number 10205576 Part number 800-01236-03
Test history 0x0 RMA number 00-00-00
EEPROM format version 1
EEPROM contents (hex):
0x20: 01 20 01 00 00 9B B9 88 50 04 D4 03 00 00 00 00
0x30: 50 00 00 00 98 10 27 17 FF FF FF FF FF FF FF FF

I thus assume that the BRI interface is OK.

A bit of history about the router - I bought it from a friend who used it as a dialin ISDN access server, I need it to support V90 for analog modem access. I changed the configuration to suite my needs. Should I rather have flashed the memory and configured it from scratch.

The router is running IOS 11.1(19)AA. Should this maybe be upgraded.

Thanking you in advance for your support.
