The DTI/PRI card uses a 9.5" by 12.5" multilayer printed circuit board
with buried power and ground layers. The clock controller and D-channel
daughterboards are fastened by standoffs and connectors. See
Figure 277

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.
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 three times and then
go into their appropriate states, as shown in
Table 351 "NTAK09 LED
states" (page 862) .
