port problem with ISDN

I have ISDN line on the cisco 3640 route. Telnet and

Ftp are fine on the ISDN line, but get time out when

running SQL application with port 1433. It's fine

to run same application on the same route with Frame relay. Please help!

Re: port problem with ISDN

compare the round trip time between the frame and the ISDN On 2 working applications.

Any access lists ?

How to know both b channels coming up?

I bulit other isdn route on the my location, it's no problem to run Sql application with port 1433 to the same route. Problem is on the U.K. office ISDN route. do you think it has difference from international call with U.S.A. local isdn call?

On the routes, we don't have any limit for port 1433.

Thanks
