RE>FWD>60 VDC Systems 16/7/96
I believe you already have the BTNR 2511, do you need that repeated. Happy to fetch any standard.

Lisa p.s. Jerry should be able to get them for us if you deem necessary. -------------------------------------- List-Post: [email protected] Date: 7/15/96 6:04 PM From: [email protected] John (Trovato), You might want to read the following ETSI standards which describe Telecommunications Power Systems Interface Requirements :- ETS 300 132-1 : Equipment Engineering (EE); Power supply interface at the input to telecommunications equipment interface Part 1: Interface operated by Alternating Current (AC) ETS 300 322-2 : Equipment Engineering (EE); Power supply interface at the input to telecommunications equipment interface Part 2: Interface operated by Direct Current (DC) Also British Telecom have a specific requirement for PSUs in Telecom Equipment connecting to their DC pwr systems within exchanges... BTNR 2511 : This is a procurement std. I hope you find this a good starting place for your designs.
