ATT TP76300, section 4 goes over installation best practices, although it doesn't cover Engineering guidelines. It's adapted from the Telcordia GR - 1275 standard, little easier to read. Is there a specific question you're looking to answer? -----Original Message----- From: NANOG [mailto:nanog-bounces@nanog.org] On Behalf Of Naslund, Steve Sent: Monday, July 18, 2016 10:18 AM To: nanog@nanog.org Subject: RE: Best practices for telcoflex -48VDC cabling & other power OSI layer 1 Not sure where to find it exactly but the Bellcore power wiring standard is what is used for central office installations. I think if you google Bellcore standard you will find what you are looking for.

Labeling, routing, organization and termination, etc. Or a recommendation on a printed book that covers this topic. Not necessarily fully oldschool "we're going to teach all the technicians how to do the kansas city stitch" stuff, but the sort of thing that's applicable in a modern colo/IP network environment.
