NETCLOCK/2™ option is enabled, time display at

the console(s) and error/warning logging time

stamps at the CEC Manager will be synchronized

to WWVB.

REDUNDANT CLOCK CONFIGURATION

The Compact CEC is factory-equipped with one (1)

Clock Board which has redundant (back-up) clock circuits.

These circuits provide clock pulse timing signals for the

Audio Boards' TDM bus circuits across the upper Card Cage

(Card Cage 1). The lower Card Cage (the CIA rack – Card

Cage 2) does not require and is not equipped with any Clock

Boards.

❏

If back-up clocking is desired, this option must be

activated by enabling it from the CEC Manager's

MOM Configuration

" screen.

NOTE

When only one Clock Board is installed in the

Compact CEC, both toggle switches – "A" and "B"

on the front of the board – must be turned on before

redundant clock operation is possible.
