12. Timing Source. Repeatedly SELECT to choose NI, Port 1, Int, or
DSX-1.
In an Integrated Access, Fractional T1 environment, ALL units must
use NI timing.
In a point-to-point configuration, one unit must
use NI timing and
the other unit must
use something else. This “something else” is
nearly always Int (Internal) but some user configurations require
Port 1 or DSX-1 timing. Contact the Technical Assistance Center if
assistance is needed.
