Replacing a DS1 CONV Circuit Pack with

the Same Type DS1 CONV Circuit Pack

Unduplicated PNC

Do not power down a Switch Node carrier to replace a circuit pack.

or DS1 Converter circuit pack on an unduplicated system disrupts service.

The service effect can range from outage of a single PN to outage of the

entire system.

boards. A TN574 cannot be combined with a TN1654 in the same DS1

CONV complex.
