Looking at the following Termination blocks inside and wondering if anyone has anything good or bad to say about them.
Circa 1890ECT1/NSC-100
Porta Systems 25100-66-M66PC

Also his cable will only be running analog and digital stations, no circuits on it at all. Should I stay with the 230v protectors are do you think I should go lower something like 100v?

No difference between them like oranges to apples, i would definitely go with the 100v

thanks perrypj, looks like I'll go with the Porta Systems then because they come with the Fuses included.

Analog stations/trunks need 235V protectors in order to not clip the ringing. Digital stations should use lower voltage - but the value depends on the operating voltage of the station. For example, for 48V digital stations, I'd use 75V protectors.
