Did you mean 2 wire lease line? Can you please post the output of "sh modem log".
http://www.cisco.com/en/US/products/sw/iosswrel/ps1834/products_feature_guide09186a00800803d6.html
What type of external modems do we have here connected on the Aux port? In the sketch you have mentioned aux port on the 2600 routers at either end however the configuration is on other lines, just want to ensure the modems are connected on the lines that have been configured for.
Thanks, Mak

Type of modem = pstn modem.
i have configured to both line 65 for my 2 2600 routers.
Regarding the command show modem log. This command is not found in IOS 12.3(10). Can you help to recommend me an IOS that i can use.

True it's a PSTN modem but will like to know the modem vendor so that we can choose the correct init string (modemcap).
These are external modems, ignore the sh modem log command.
Thanks, Mak

The modem vendor is Zyxel. (model U-336S).
11-11-2004 10:23 PM
You will need to get the modem vendor involved so that we get the correct AT commands from them for the below requirements for lease line support.
* The answering modem AA register is set to 1 (AA=S0=1) so that autoanswer is "on".
* The originating modem AA register is set to 0 (AA=S0=0) so that autoanswer is "off".
Basically we need commands similar to the above.
Also need to find out whether the Zyxel modem supports LL functionality & what's the command for that? For example Cisco NM-AM modems use &L2, that is if the autoanswer feature (AA) is used, both the originating and answering modem must be put into leased line mode with the &L2 AT command.
Thanks, Mak

The zyxel modems support 4wires LL and AA. These can be configured from the modem LCD. The modem back to back has been proved working when i use both PCs as DTE.
Is there any debug command that i can try to use on the router to find out what went wrong. or can you help to advise if the attached configuration from cisco correct to setup up the aux back to aux back.
any other help is welcome
