MTP Dual Port Ram Test (#104)
This test is destructive.
The test terminates any PPN Manager I session, and it is a coordin ated test of the
MTP dual port ram (DPR). The DPR is a section of memory that is shared by the
MTP and by the 80286/386 Processor circuit p ack. Control messages and data
are passed through the DPR. The test forces both sid es to read and write the
DPR simultaneously in alternate locations.
The DPR test causes the PPN Manager I to log off before the test result is
displayed. The test result is determine d according to the terminal from which the
test is run. If the test is run from the PPN Manager I terminal, system technic ian
should log bac k in and examine the Error Log for an error ag ainst PR-MAINT, with
Error Type 769, no Aux Data. This error entry indicates that the MTPDPR Test
failed and that the Processor circ uit pack should be replaced.
!WARNING:

If the TN786B circuit pack mu st be replaced , and if there is a blank in the

Expansion Memory circuit pa ck slot (that is, in the slot immediately to th e

right of the TN786B circuit pac k), remove the blank before removing the

circuit pack. Otherwise, the circuit pac k and/or the two connec tors that are

used to connect the Expansi on Memory circuit pac k (if available) might

become damaged.
If the test is being run from a terminal other than the PPN Manager I (for example,
EPN Manager I, remote access, and so forth), the te st results are displayed on
the screen.
10304 FAIL MTP reported test failure. The system is not able to reliably contact INADS
with alarm data. The system continues to provide good service.
1. If MTP Outpulse Relay Test (#102) is also failing, check for the
presence of the INADS trunk, and resolve any INADS trunk problems.
2. If Test #102 passes, the fault is on the Processor circuit pack. The
circuit pack should be replac ed at your convenience.
PASS MTP detected correct data throug h the loop back connection.
1. If the system cannot call INADS, or if INADS cannot contact the
system, check with the local Central Office for problems with the
INADS trunk, and verify that the INADS number is correct.
