Norstar systems are stratum 4E equipment and are usually 
used as termination points in a network.
For each DTI, choose one of the following settings:
Primary reference
The DTI obtains the timing reference from the network, which 
the system synchronizes to. This is the default value for the 
DTI in slot 1 in the ICS. If the system is configured with a DTI 
card that has been configured as PRI, the setting should be set 
to Primary.
Secondary...
