Hardware Mode Application
shows a typical LXT350 application in either a T1 or E1 environment. See
through
to select the transformers (T1 and T2), resistors (Rt and R
L
) and capacitors (C
L
)
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 C
L
, or eliminating it completely. Excessive
capacitance at C
L
will distort the transmitted signals.
