A 60Km cable serving a client on a PSTN was tested by the installation engineer during installation and obtained Characteristic impedance of 68 at -0.7 degrees Ω. The impedance at the sending end was 115 - j 138 when line was open circuited at the load end. i. Evaluate the sending end impedance if the client end is open circuited.

Question
A 60Km cable serving a client on a PSTN was tested by the installation engineer
during installation and obtained Characteristic impedance of 68 at -0.7 degrees
Ω. The impedance at the sending end was 115 - j 138 when line was open
circuited at the load end.
i. Evaluate the sending end impedance if the client end is
open circuited.
