1.2 Detailed Level Procedure 703
1. Locate Clock Wiring
To connect a T1 clock input to Total Access 3000/3010, Determine the “+”, “-“
and drain or shield wires from the CO clock source.
2. Strip the Ends of the Clock Wire for Wire Wrapping
Using wire strippers, strip 1 inch to 1-1/2 inches of the insulation from the end of
the clock source drop wire.
3. Connect the “+” Lead
Using the wire-wrap tool, wire wrap the “+” wire from the clock source to the pin
marked “+” on connector P18/P11, “EXTCLK B-IN.”
4. Connect the “-” Lead
Wire wrap the “-” wire from the clock source to the pin marked “-” on connector
P18/P11, “EXTCLK B-IN.”
5. Terminate the Shield Drain Wire
Trim the shield wire flush with the insulation. Do not wire wrap to the “S” pin.
6. Dress Out the Wiring
Route the clock wire out of the right side of the frame and neatly tie it down.
7. Connect Secondary T1 Clock if Required
To Connect a secondary T1 clock to the Total Access 3000/3010 shelf, repeat
Steps 2 through 6, using connector P24/P13 “extclk C-IN” instead of connector
P18/P11, “EXTCLK B-IN”.
