MH89760B
Preliminary Information
interfaces is selected as the synchronization source
by enabling its output through the Master Control
Word of the chosen interface. Phase-locked loop #2
will then generate ST-BUS clocks that are
synchronized to either the T1 network or the CEPT
network. Phase-locked loop #1 is configured to
generate the T1 transmit clock synchronized to the
ST-BUS. Therefore, if the ST-BUS is synchronized to
one network then the elastic buffer in the opposite
interfaces will perform controlled slips between that
network and the T1 to CEPT converter.
