Figure 6 - Input/Output Configuration
to the transformer when either of the transistors is
turned on. By operating in the transient portion of the
inductance
response,
transformer produces an almost square pulse. The
capacitor and inductor on the center tap of the
transmit transformer shown in Figure 6 suppress
transients in the 12 volt supply. The series RLC
across the output of the transformer shape the pulse
to meet the AT & T or CCITT pulse templates. A

Note:
The equalizer has been optimized for 22 gauge ABAM
cable. The exact distances may vary with the type of cable and the
output transformer. Different line length settings may be
required if a transformer other than the Filtran TFS2573 is used.
