Hardware Mode Application
Figure 12 shows a typical LXT350 application in either a T1 or E1 environment. See Table 18
through Table 19 to select the transformers (T1 and T2), resistors (Rt and RL) and capacitors (CL)
needed for this application.
Note: If the application includes surge protection, such as a varistor or sidactor on the TTIP/TRING lines,
it may also require reducing the value of the capacitor CL, or eliminating it completely. Excessive
capacitance at CL will distort the transmitted signals.
