The DTI/PRI card uses a standard IPEsized (9.5" by 12.5"), multilayer
printed circuit board with buried power and ground layers. It is keyed
to prevent insertion in slot 10. The clock controller and D-channel
daughterboards are fastened by standoffs and connectors.
The NTAK09 DTI/PRI card has seven faceplate LEDs. The first five
LEDs are associated with the NTAK09 card, the remaining two LEDs are
associated with the clock controller and DCHI daughterboards.
In general, the first five LEDs operate as follows:
• During system power up, the LEDs are on.
•
When the self-test is in progress, the LEDs flash on and off three
times, then go into their appropriate states, as shown in Table 316
"NTAK09 LED states" (page 760).
