As400 Keep Alive Command

I am looking for information about allowing 2 Cisco 2500 to allow Keep Alive calls from an AS400 to pass through each router.

Two Offices, 2500 at each office, AS400 located at one, both offices access the AS400 but the remote office periodically get dropped. Lines have been tested, IBM indicates that the routers are dropping or ignoring the Keep Alive command from the AS400.

Any suggestions?

Thank You,
