INTRODUCTION

This manual provides operation procedures for use with any ADC DSX-1 cross-connect system. The procedures are illustrated

with a generic circuit diagram that can be applied to any DSX-1 circuit module. The diagram indicates that some features such as

a Monitor In (MON IN) jack may or may not be present. Also, the diagrams show tracer LEDs on the cross-connect side of the

circuit modules only; in some applications LEDs are present on both front and rear of the circuit modules.

All jumpers in the left-hand side of the cross-connect field

should enter and leave the bay from the left vertical

wireways.

All jumpers in the right-hand side of the cross-connect field

should enter and leave the bay from the right vertical

wireways.

All intrabay cross-connects should use the vertical rings

except when terminations are in the same panel.

All interbay cross-connects should use the horizontal

wireways.

All jumpers originating in the upper half of the cross-connect

field should route via the upper horizontal wireways.

All jumpers originating in the lower half of the cross-connect

field should route via the lower horizontal wireways.

Step 1. At each office, patch from the DSX MON OUT of the Equipment to the IN jack of a Bridging Repeater.

Step 2. At each office, patch from the OUT jack of the Bridging Repeater to the DSX IN jack of the Standby Facility.

Note: Steps 1 and 2 must be completed at each office before proceeding to Step 3.

Step 3. At each office, patch from the OUT jack of the Standby Facility to the DSX IN jack of the Equipment. The

patch cord must be placed in the Standby Facility DSX OUT jack first to avoid interrupting service.

Step 4. Terminate the DSX OUT jacks at each office.

Note: The patch cords should be removed from the Equipment end first during restoral.

Step 1. Patch from the DSX MON OUT jacks of the Equipment to DSX IN jacks of Maintenance Line at each office.

Step 2. Patch from the DSX OUT jacks of Maintenance Line to DSX IN jacks of Equipment at each office.

Step 3. Terminate the DSX OUT jack of the Equipment at each office. To remove patches without service

interruption, reverse these steps in the exact sequence.

Caution: For in-service patching, each step must be completed at both offices before proceeding to the next step.

Note: Bridging Repeaters are located in the Office Repeater Bay as part of the Maintenance Line.
