When you are troubleshooting, do not open any cable connections. Opening a connection

can expose you to fatal shock by high voltage. If you find it necessary to remove or replace a

component, or a piece of cable in the system, use your order wire hookup and call MUX

equipment operators. Tell them to remove the power from the cable hookup.

Organizational troubleshooting of twin coaxial cable assemblies is limited to testing a PCM cable

hookup of the following items using the telephone set (l):

twin coaxial cable assemblies

1 mile away from where you connected the telephone test set.

Localize the trouble in an unattended repeater to one of the two circuit paths.

Provide order wire communications between the operator of the telephone test set and the MUX
