Physical description 863
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
"NTAK09DTI/PRI circuit card" (page 863).
The NTAK09DTI/PRI card has seven faceplate LEDs. The first five LEDs
are associated with the NTAK09card. Theremaining 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 Table351 "NTAK09 LED
states" (page 862).
