Figure 86: Facility Fault Sectionalization<br />

START (DS1 Interface refers to the TN722, TN767 or TN464 circuit pack.)<br />

Since this technique is time-consuming, first fix any DS1-BD,<br />

UDS1-BD, STRAT-3 or SYNC <strong>error</strong>s that are not slip <strong>error</strong>s.<br />

Enter busyout board<br />

for the DS1 Interface.<br />

This circuit pack should<br />

not be the on-line<br />

synchronization reference.<br />

Loop transmit to receive on the<br />

G3r side of the equipment<br />

connected to the DS1 Interface.<br />

(See Note 1).<br />

Execute the Slip Alarm<br />

Inquiry Test (#144) via<br />

<strong>test</strong> board comm<strong>and</strong>.<br />

(See Note 2).<br />

FAIL<br />

The fault lies before the<br />

loop-around point. Repair<br />

or replace the defective<br />

wiring or circuit pack.<br />

If the problem cannot be<br />

identified, escalate the<br />

problem.<br />

PASS<br />

The fault lies beyond the<br />

loop-around point. Remove<br />

the loop-around <strong>and</strong> rewire<br />

the connections. Is the<br />

unit just <strong>test</strong>ed the last unit<br />

on the G3r side of the<br />

maintenance boundary?<br />

NO<br />

Move the loop-around point<br />

to the next unit toward the<br />

span line side. Loop transmit<br />

to receive on the G3r side of<br />

the next piece of equipment.<br />

SYNC (Port Network Synchronization)<br />

YES<br />

Restore service:<br />

enter release<br />

board for the<br />

DS1 Interface.<br />

Report to the<br />

appropriate<br />

personnel that<br />

the problem is<br />

beyond the<br />

maintenance<br />

boundary.<br />
