John,
            First thing is you must identify what type of interface your
serial port is emulating.  The only two choices
you have are DTE and DCE.  DTE devices(normally the router) receives a clock
from the DCE(normally the CSU/DSU or network equipment) provides the clock.
On the AGS's I hope you've got the HD V.35, 26 pin Serial interfaces because
those are the only one that support the cables to allow back-to-back router
connections to the 2500 routers(HD60) interfaces.  The other thing is to
support the DCE function on the AGS side you must change the jumper settings
on the card it self to make it a DCE capable device.  The cards comes
default with the jumper settings to DTE.  Here is the link that should
answer any other questions you may have...

Also, don't forget the command "sh controller <mci/sci>"to see what the
ports are configured to.

HTH
