I’m considering Asterisk / Digium as a replacement to my existing phone
switch. I need to continue to be able to push analog lines between
multiple buildings in a campus environment.
The Digium Analog 410 Card manual states it’s not recommended to go
beyond 1500 feet distance for an FXS card, and no line should leave the
building or be bundled. The 2400 Series Manual does not have this same
notice. Should it?
My potential application will be pushing all of 1500 feet and maybe a
teeny bit more. Analog lines will be bundled into PE-89 type
direct-burial rated cable in capacities ranging from 100-pair to
500-pair. All cable pairs are 24AWG. All cable is privately owned by the
organization. All cable is professionally terminated on each end to
grounded building entrance protection with lightning blocks / surge
protection. This infrastructure has been in place and working on an
existing “old school” digital switch with port cards that don’t have
lightning or surge suppression built in, just like the Digium cards.
Has anyone run a similar configuration and can speak for or against such
Thanks for the help and input,
