Will,

The cube is sitting on a 10bT hub. That hub is uplinked to another 10bT hub
which is connected to a Cisco 2610 router which is connect to Frame Relay
over Frac-T1 (384k to the cloud) The remote side is connect via 64k line to
the cloud, Cisco 1600 router and then 10bT hub.

The troubling fact is that this exact same setup is used to connect to
multiple remote sites, in the exact same configuration, none of which is
experiencing the same problem.

Does this change anything or help you in any way point me at some trouble
shooting ideas.

Thank You,
Josh
