Connecting 2 2621XM with two modems as a backup

Hi all,

Am facing a little confusion.

Here the point :

I have 2 2621XM with 2 WIC 2 A/S to connect using a LL and 2 modems. this connection is just a backup to an existing E1 link.

Is it necessary to configure my serial interfaces on async mode ?

First i used 2 SS-RS232 DCE cables but it does nt work, the interface is continuosly on reset status. I think I need DTE cables, is it true ?

Thanks for ur assistance.

Best Regards

Yes, you need DTE cables to connect the modems. sync or async depends on the type of the modem.

what dp u mean by it depends on the type of the modem?

Thanks for ur help.

Type of modem, sync or asynch ?
