TEST 2 X=NG Y=NG X=00000 X=00000

TEST 2 =NG

Where:

X= RCTUA, RCTUBA, RCTUC, B1CU, B2CAU, B3CAU, B5CAU

Y= RCTUD3, RCTUF, B2CBU, B3BU, B5CBU

OK = RAM is good

NG = RAM is defective

An X=NG or Y=NG RAM test result indicates a defective RCTU PCB; change the appropriate (X or Y) processor PCB and retest RAM on the newly installed processor PCB.

Replace the DK14 or DK40i Base KSU if Test 1=NG.

Program 00 Part 2 - Overview

Use this program to test the RAM on system processor. If a RAM test error occurs during this test, the processor causing the error should be replaced. In the case of two-PCB processors, isolation of a RAM failure is indicated on the programming telephone X or Y (see above).

If the DK14 or DK40i processor fails the RAM test, the Base KSU must be replaced.

CAUTION! Running each RAM test drops all calls and interrupts telephone service for 15 seconds.

Note Running Program 00 RAM tests do not change or erase any customer data.
