System Clock Source
The clock source provides the reference point for all voice and data traffic in the system. There can
only be one clock source for the system, otherwise clock slips may occur on the other T1 interfaces,
resulting in noise on voice lines and errors on data circuits. Options include
INTERNAL
,
t1 0/1
, or
t1 0/2
.
The default clock source is
t1 0/1
. Change the clock source by clicking on the
