Description
The test synchronization command makes sure that the proper sources are 
being used for timing synchronization and updatse the boards with the correct 
synchronization parameters. The tone-clocks, DS1s, and EIs are all sent 
down-link messages to place them in the correct synchronization configuration 
given the current on-line synchronization reference.
The synchronization subsystem provides error free digital communication 
between the switch and other PBXs, COs, or customer premise equipment. The 
subsystem is made up of: TDM bus clock, DS1 trunk board, and maintenance 
and administration software resident in the SPE.
