Nortel Door Phone SAPS Required due to distance from KSU

[rburgener]

We are installing a Door Phone at a large Campgrounds gate. The cabling is just over the 1000' max that can run off the station port. If we use the SAPS(Station Auxiliary Power Supply) it will extend the working distance to 2600'

Currently the Door Phone is right on the edge and working about 50% of the time.

Would any one know the correct voltage required ie. 12/24/48 AC/DC?

Thanks for your help
Ryan
