Procedure 4 consists of two parts. Part 1 attempts to clear the packet-bus fault by
replacing every bus cable and terminator within an EPN. Part 2 attempts to
isolate the fault to a particular carrier by extending the packet bus from the control
carrier to additional carriers one at a time.
Part 1:
1. Power down the port network.
2. Replace every TDM/LAN cable assembly and both of its TDM/LAN
terminators.
3. Restore power to the port network.
4. Determine whether the packet-bus fault is still present.
5. If the packet-bus fault is resolved, the procedure is completed. Otherwise,
go to Part 2.
Part 2:
1. Place the Maintenance/Test circuit pack into the carrier where the active EI
circuit pack resides to isolate the failure to the smallest possible number of
carriers.
2. Power down the cabinet and terminate the packet bus on the carrier with
the Maintenance/Test (M/T) and active EI.
