Installing a New DTIC Card in an Existing Installation
1. On the new DTIC card, check that the DTIC’sSW1 and SW2 switches at the bottom right-hand
corner of the card are set to the correct positions based on the type of DTIC−E1adapter installed on
the back of the system (at the specified I/O slot location): 75-ohm or 120-ohm. These switches and
their settings are marked on the card.
2. While holding the top and bottom edges of the card, slide the DTIC into the card cage.
3. Pivot the card ejectors as needed to grip small flanges on the front edges of the card cage.
4. Firmly seat the DTIC connectors into the motherboard by pressing ejectors against the front edge of
the card. The ejectors clip onto small pins on the DTIC when the connectors have seated.
Caution!
No more than one DTIC card at a time may be
removed or installed with power ON.
5. The information for the DTIC card is downloaded from the system and the DTIC becomes
operational.
When the DTIC is installed the uppermost red LED comes ON. When self−testdiagnostics are
complete the red LED remains ON and the uppermost green LED comes ON. This indicates that the
card is ready for application code download and initialization.
When the card is operational, only the uppermost green LED remains lit. This indicates the DTIC
application code is operating normally. The green LED stays ON even if problems are detected with
the E1 trunk or other aspects of initialization. However if there are problems, the LEDs below the
green power LED indicate the nature of the problem. Otherwise, the other LEDs remain OFF. Refer
to the following table for the LEDs and their meanings.
LED Meaning
Red boot (top) AP code is initializing
Green Power DTIC has successfully com-
pleted self diagnostics
Red 1 (top) Loss of signal on trunk (LOS)
Red 2 Loss of frame on trunk (LOF)
Yellow3 Remote alarm indication (RAI)
Yellow4 “Other” trunk alarm
Yellow5 Alarm history
Green 6 (bottom) One or more channels off hook
6. If the DTIC is being hot-plugged, initialize the ports by entering
CUxyz
where xis the slot, yis the first port in the card, and zis the last port in the card. If yand zare not
specified, the server defaults to all ports on the card.
7. Test the system for proper operation.
8. Close and lock the cabinet door.
