Internal is the default selection after test set
preset and covers the situation when a hard
loop is configured at the far end. If a separate
test set is used at each end, then the test set on
one end should have the TX Clock set to
Primary Rx (assuming the incoming signal is
connected to this jack). Another alternative is
to use a second T1 circuit connected to the
Secondary Rx jack to establish proper timing.
