:
This method can only be used if the XRT73L03B is
operating in the HOST Mode.
If either of these methods are used to disable the
HDB3/B3ZS Encoder, then the LIU transmits the data
as received via the TPData_(n) and TNData_(n) input
pins.

The Transmit Pulse Shaper Circuitry consists of a
Transmit Line Build-Out circuit which can be enabled
or disabled by setting the TxLEV_(n) input pin or
TxLEV_(n) bit-field to “High”or "Low". The purpose of
the Transmit Line Build-Out circuit is to permit config-
uration of each channel to transmit an output pulse
which is compliant to either of the following pulse
template requirements when measured at the Digital
Cross Connect System. Each of these Bellcore spec-
ifications state that the cable length between the
Transmit Output and the Digital Cross Connect sys-
tem can range anywhere from 0 to 450 feet.
The Isolated DSX-3 Pulse Template Requirement per
Bellcore GR-499-CORE is illustrated in Figure 19 and
the Isolated STSX-1 Pulse Template Requirement
per Bellcore GR-253-CORE is illustrated in Figure 20.
