Cable

Function

W216

See table 2-2.

W218

Connects digital processor test set serial interface test

(computer interface simulator) output to the communication

processor.

W219

Connects the communication processor control-indicator

interface circuits to the digital processor test set to

evaluate the ability of the communication processor to

exchange control-indicator status words.

W220

Transfers address from the communication processor ROM

extender CCA to the digital processor test set diagnostic ROMs.

The diagnostic ROM instructions are transferred back to the

communication processor ROM extender CCA via this cable.

W221

Transfers communication processor digital processor bus and

In addition, this cable transfers digital processor test

set manual digital processor control signals (such as HALT,

SINGLE STEP, RUN START) as well as the manual address input

(ASWO thru ASW15) to the digital processor.

W222

Transfers 3- - ac blower power to the communication

processor blower.

W223

Transfers dc power to the unit under test.

W224

Coaxial cable that transfers the XMIT DATA from communi-

cation processor crypto interface output CCA A18 to com-

munication processor transceiver I/O ECA A30.

W225

Coaxial cable that transfers the RCV DATA from communication

processor transceiver I/O ECA A30 to the communication

processor crypto interface input CCA A17.

W226

Coaxial cable that transfers the extracted RCV CLK from

transceiver I/O ECA A30 to communication processor crypto

interface input CCA A17.

W227

Coaxial cable that transfers the XMIT CLK from communication

processor transceiver I/O ECA A30 to communication

processor crypto interface output CCA A18.

W216, W217

See table 2-2.

W228

Transfers +5-V operating power and an output status word

for testing the control-indicator display circuits.
