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
