Re: (ASCEND) TNT Reboot Requests

[Jason Nealis <nealis@rcn.com>]

This is a good thing, If I remember this feature correctly what happens is after each disconnect
there is a little daemon that tests the integrity of the firmware/status of that individual DSP
if it fails any of these internal testing then the TNT reboots that individual DSP and forces it
to reload the firmware. This way any degradation that may have been happening to the TNT's over
time will no longer happen because it get's addressed in real-time. We had asked them to implement 
this awhile ago because there is a severe degradation of DSP's in the TNT. This of course will
address this problem.
