• Activating octal density with the MC32 feature density doubles the
WTN capacity of the CMCC, CMRC, and CMLC cards
• When installing cards into an Option 11 core or expansion cabinet, note
the actual slot location of the CMCC. You will need to verify this
location when programming the system (see “CMCC slot” on page 84
for more information).
Faceplate 60-wire cabling connects the CMCC to the other cards in a
daisychain. A long faceplate cable (bypass faceplate cable harness) is
available to connect cards across the NT8D01 Controller card if necessary.
Normal LED behavior upon installation
All Companion cards are equipped with a card status LED. The CMCC is also
equipped with a system LED, labelled SP (system processor).
The card LED is the top LED on the CMCC and the only LED on the
expansion cards. It is not labeled on any cards. If the LED is on, the card is out
of service and can be safely removed. If the LED is off, the card is in service
and should not be removed. The difference between a regular line card and a
Meridian Companion card is that the Meridian Companion card must be
disabled from both the Meridian 1 and the Meridian Companion sides before
the LED goes from off to on. Conversely, for a completely disabled card (LED
is on) the LED goes off instantly when the card is enabled from either side.
ATTENTION!
If the card slot address requires an adjustment and you do
not make this adjustment, the WTN addresses will not be
consistent with the M1 addresses.
