It depends exactly upon what equipment is connected to the network cable.
iirc telephone's use 50v (whether this is just for the ring I'm not sure)

It's 50VDC with 100VAC ringing. 


A far greater risk is in mixing between ISDN2 (on the S-BUS side) and
ethernet. Since these use the same connectors...

Also ISDN lines have 100V on them rather than the 50V of POTS.
