Data Channel Dual Port RAM Test (#108)
This test is destructive.
This is a coordinated test of the dual port RAM that is shared between the
hardware and software composing the DATA-CON. Control messages and data
are passed through this dual port RAM to establish and tear down connections
over the DATA-CHLs. This test requests each side to read and write the dual port
RAM, first one at a time and then simultaneously in alternate locations.
This test prevents any control stimuli from being received from or sent to the TDM
Bus control channel preventing the establishment of new connections over the
DATA-CHLs. However, existing connections are not (and cannot) be dropped.

10704 ABORT Internal system error
1. Try the command at 1-minute intervals a maximum of 5 times.
Any FAIL The circuit pack failed to reset.
1. Execute the command again.
2. If the problem persists, replace the TN777 Network Control circuit
pack.
After the Network Control circuit pack has been replaced, its Time-of-Day
clock must be set using the set time command. If this is a high or critical
reliability system, set the Time-of-Day clocks as described in Chapter 6,
"Reliability Systems: A Maintenance Aid", to ensure that the clocks on both
Network Control circuit packs are synchronized.
PASS The circuit pack initializes correctly.
