Transmit Clock

Selects the source of the clock used to transfer data from the DTE to
the T3SU 300. Use the following chart to determine your selection:

Configuration Selections for DSX-1 Interfaces

The configuration selections listed in Table 3-3 on page 52 are
available for Quad DSX-1 interfaces. Separate selections can be
made for each of the four DSX-1 ports of the card. This menu is
shown in Figure 3-5 on page 52.

N

ORMAL

you want the transmit clock to be derived from the
T3SU 300.

I

NVERT

your DTE device cannot provide a transmit clock
signal and data errors are present between your DTE
and the T3SU 300.

E

XTERNAL

you are transmitting at high rates. This selection
eliminates data errors caused by excessive delays in
the DTE transmit clock receiver, transmit data driver,
and cable length.

Selecting Normal or Invert clocking options depends on your DTE,
cable length, and cable characteristics. To verify error-free
operation, perform a DTE loopback test and a BERT test from the
DTE. See the chapter, Diagnostics, on page 85 for information on
performing these tests.
