The third configuration (refer to Figure 10) establishes a MCDN TIE trunk
link by connecting two Meridian 1s through a direct line between two
back-to-back SILC interfaces. This configuration can be used in campus
environments, although it is not recommended because of the lack of
protection devices and because of the distance limitation of 1 km. Clock
synchronization may be achieved by having one of the Meridian 1s derive
clock reference from the BRI TIE trunk connection or from any other
PRI/DTI/BRI connections if available. The other Meridian 1 may be allowed
to operate in free-run mode or derive the clock source from any PRI/DTI/BRI
connections if available.
