920 NTAK20 Clock Controller daughterboard
External timing interface
The clock controller provides an external timing interface and accepts two
signals as timing references. An external reference is an auxiliary timing
clock which is bridged from a traffic carrying signal and is not intended to
be a dedicated non-traffic-bearing timing signal. The clock controller uses
either the external/auxiliary references or the DTI/PRI references.
