Star Hub To Rcc2 Speech Path Diagnostics; Speech Path Diagnostic Program For The Rcc2 - Nortel DMS-100 Series Maintenance Manual

P-side interface presence test This test is identical to the speech path
diagnostic program. This test checks that all LTC P-side links to be tested
continue to be present. This test flags missing or failed NT6X50 cards in the
LTC.
Full peripheral test After the first two tests in the P-side link diagnostic
program, this test makes sure necessary hardware is present. The full
peripheral test checks one speech channel on each defined LTC P-side link to
the Hub. This test is run when the LTC is in active mode.

Star Hub to RCC2 speech path diagnostics

The RCC2 diagnostic program includes the following two tests:
• Speech path diagnostic (SPCHDIAG) program - tests all internal
components of the RCC2 speech path for data integrity, including central
side (C-side) and peripheral side (P-side) loop-arounds, and speech bus
time slots.
• P-side link diagnostic (PLNKDIAG) program - tests links between the
RCC2 and any secondary peripherals, including the Star Hub. The system
performs these tests on either all links or selected links.

Speech path diagnostic program for the RCC2

The speech path diagnostic program includes four separate tests:
• Hardware presence test
• P-side interface presence test
• P-side loop test
• Internal loop test
Each test starts when all previous tests have passed.
Hardware presence test
This test checks for the presence of message (NTMX76AB) and timeswitch
(NTMX75) cards in the RCC2.
This hardware is necessary for the remainder of the tests. If any one of these
cards is not present, the diagnostic program returns a No Resources error
message and produces a PM181 log report.
P-side interface presence test
This test checks that DS-1 interface (NTMX81) cards, entered in table
RCCPSINV for the RCC2, are present. The test prepares for the P-side loop
test.
