There is a Cisco 1751 router that requires 2 ISDN BRI cards or 1 BRI card with 2 ISDN ports on it. However, there is already one ISDN BRI card and WIC-2T card installed. Is there any possibility of buying a2-port ISDN BRI card. I am not very sure if Cisco makes one of them.
Thanks a lot Regards Gautam
