ETR-PT (Enhanced Tone Receiver Port)
The threshold number of ports for service is administered using the
change system-parameters maintenance command.

UUCSS, and release board UUCSS. Reset is required to reload
RAM associated with the TN744's DSPs. This will take all eight tone
detector ports out of service for a few seconds. Only four of the
eight would be out of service due to the alarm. (There are four tone
detectors on each of the two DSPs.) Other than the unlikely
potential of running out of tone detector resources in the switch,
there is no other effect when the board is reset.

the error. The long test resets the board and is required to reload
on-board RAM associated with the DSPs. The effect is that tone
detectors are taken out of service momentarily and tones are
removed from the TDM bus for about 10 seconds. This means no
dial pulses or touch tones during this interval, which probably will not
affect calls in progress but could cause a call origination to abort or
cause a user to not get dial tone when going off hook.
