This section contains information on the following topics:
Introduction
Digital trunking requires synchronized clocking so that a shift in one clock 
source results in an equivalent shift in all parts of the network. 
Synchronization is accomplished with an NTAK20 clock controller 
daughterboard in each MG 1000S that contains a digital trunk card.
The NTAK20 clock controller daughterboard mounts directly on the 
following cards:
NTAK09 1.5Mb DTI/PRI
NTBK50 2.0 Mb PRI
NTRB21 DTI/PRI/DCH TMDI 
NTBK22 MISP 
NT6D70 SILC
NT6D71 UILC
