Configuration Settings: Line
Clock Quality
Calls between systems using digital trunks (for example E1, E1R2, T1 PRI and BRI) require an common clock signal. The
system will try to obtain this clock signal from an exchange through one of its digital trunks. This is done by setting the
Clock Quality setting of that Line to Network. If there are multiple trunks to public exchanges, another trunk can be set
as Fallback should the primary clock signal fail. Other trunks should be set as Unsuitable.
