Hey Tom, There are a number of different flavors you can pick. For Telcordia, the objective in GR 499 has the widest swing. We do ours from -40 to -60VDC. The extra head doesn't cost us anything as it keeps us within the SELV limits and makes us look good to customers who wonder why the other guy's equipment only goes to 57.5VDC, the inference being ours is better. Here is a list of various standards requirements:
-40.5 to -57.0 VDC ETS 300 132-2:1996 -42.75 to -56.7 VDC ANSI T1.315:1994 -40.0 to -57.5 VDC AT&T NEDS 9069:1999 -42.5 to -56.5 VDC GR-499:1995 (-40.0 to -57.7 objective) Have a Great Day!

I suspect the range is something like 42VDC absolute minimum and 56VDC absolute maximum, but it would help to have a reference. Also, are there any RBOC generated docs that cover this? Thanks.
