1295.0. "DECbrouter 90T1 line protocol down Prob!" by ALBANY::PEPLOWSKI (Paul Peplowski (Peppy) Albany N.Y. dtn:344-7228) Thu Apr 10 1997 20:02

    Hi:
    
    	I have a customer that has a 56kb link from the U.S to Ireland 
    and about every two to three months the link comes up with a status of 
    serial 0 up line protocol down on the Ireland side. the line checks out
    with Telco and the way the customer gets it back is to reseat the
    module in the hub. the unit is a DECbrouter 90 T1 running ver 9.14 and
    9.1 firmware. Has anyone had this problem? Any help Would be greatly
    appreciated.
    
    					Thanks in advance

This seems like a signaling problem from the DCE end. Reseating the DECbrouter is probably just reseting the signal states. I'd suspect the DCE device. You may try plugging the DECbrouter into a standalone power supply just to see if it could be HUB based power related but I'd be supprised if this was the case. >the unit is a DECbrouter 90 T1 running ver 9.14 and >9.1 firmware.

Hi Paul,

    What type of Network link is it? and what is the DCE device connected?

    >the way the customer gets it back is to reseat the module in the hub.

    This seems like a signaling problem from the DCE end. Reseating the
    DECbrouter is probably just reseting the signal states. I'd suspect
    the DCE device. You may try plugging the DECbrouter into a standalone
    power supply just to see if it could be HUB based power related but
    I'd be supprised if this was the case.

    >appreciated.

    I am not aware of any 9.14 specific problems but I do need to see the
    configuration of the router as well as know more about the Network config
    specifically with regards to the Telco end, type of CSU/DSU and config.
