Telegraph and telephone lines were very sensitive to solar flares as they are basically giant antennas; designed to operate at low voltage, a minor voltage spike from a flare may create havoc at the terminals.
Power lines are less sensitive as the voltage is higher and the apparatus attached to it are designed to handle high voltage. Shielded and underground lines should be safe anyway.
Telecommunication is using higher frequencies, meaning smaller antennae and less vulnerability.
A huge solar flare would create problems, you bet. But nothing like a total system collapse.
