100pr outside plant cable between buildings

100pr outside plant cable between buildings

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?

RE: 100pr outside plant cable between buildings

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


RE: 100pr outside plant cable between buildings

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

RE: 100pr outside plant cable between buildings

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.

RE: 100pr outside plant cable between buildings

mforrence is right. Go higher than you need to be safe.
