ADCP-80-314 • Issue 6 • January 2001 • Section 3: Operation
This procedure is used to bypass a Failed Facility without the use of bridging office repeaters.
It is recommended to use Procedure 3 "In-Service Patching To Bypass A Failed Facility"
whenever possible to ensure service is not interrupted when removing patch cords. This
illustration represents the near end office. A similar corresponding far end office patch must
also be performed, but is not shown.
STEP
PROCEDURE
1
Select a Standby Facility where communication between the two interrupted sites will be
temporarily routed to.
2
At both sites interrupted by the Failed Facility, patch the Office Equipment to Standby
Facility using patch cords as follows:
(a) Connect the Office Equipment OUT jack x to Standby Facility IN jack y.
(b) Connect the Standby Facility OUT jack z to Office Equipment IN jack {.
3
Service is now temporarily restored between the interrupted sites.
4
After the Failed Facility is repaired, remove all patch cords to restore service between the
interrupted sites.
