Description / Recommendation<br />

Stratum-3 Clock Alarm Query (#649)<br />

1 FAIL Either Reference A failed or CI card A failed. This condition usually<br />

indicates a failure of the DS1 reference. However, there may also be a<br />

failure of the CI card to which the reference is connected. The system<br />

technician dispatched to investigate this problem should take a spare CI<br />

card in case the CI card caused the failure.<br />

If you are NOT ON-SITE, use the following procedure:<br />

1. Enter display <strong>error</strong>s <strong>and</strong> look for DS1-BD <strong>error</strong>s. See DS1-BD<br />

(DS1 Interface Circuit Pack) for the recommended repair<br />

procedures.<br />

2. If there are no DS1-BD <strong>error</strong>s or after resolving every DS1-BD<br />

<strong>error</strong>, enter <strong>test</strong> synchronization r 4 to see if the alarm still<br />

exists. If every <strong>test</strong> repetition passes, the alarm no longer exists.<br />

Otherwise, the system technician should be dispatched with a spare<br />

CI card to use the following instructions on-site.<br />

If you are ON-SITE, use the following procedure:<br />

1. Look for a red LED on CI card A (i.e., the left CI card). If there is a<br />

red LED, replace the CI card if a spare is available. If no spare CI is<br />

available on-site, proceed to Step 3.<br />

2. If, after replacing the CI card, the red LED on the new CI card also<br />

lights, proceed to Step 3. Otherwise, enter <strong>test</strong> synch r 4 to<br />

clear the alarm. If any <strong>test</strong> repetitions fail, follow the procedure for<br />

those failures.<br />

3. Enter display <strong>error</strong>s <strong>and</strong> look for DS1-BD <strong>error</strong>s. If there are<br />

<strong>error</strong>s, see DS1-BD (DS1 Interface Circuit Pack) for the<br />

recommended repair procedures. If there are no DS1-BD <strong>error</strong>s,<br />

then proceed to Step 4.<br />

4. After every DS1-BD <strong>error</strong> has been resolved or if there are no<br />

DS1-BD <strong>error</strong>s, enter <strong>test</strong> synch r 4 to clear the alarm <strong>and</strong> see<br />

if the alarm still exists. If any <strong>test</strong> repetitions fail, follow the<br />

procedures for those <strong>test</strong> failures.<br />

5. Check the DS1 reference A connections to the Stratum-3 clock.<br />
