Hi Jack, Would this by any chance be the Jack Murphy that used to work at DSG about ten years ago?
To answer your questions: GR-63-CORE deals with c.o. environmental GR-487 deals with cabinet enclosures Both specs available from Telcordia at: http://telecom-info.telcordia.com/site-cgi/ido/index.html Operating c.o. temp is 5 to 40 deg. C Short term c.o. is -5 to 55 deg C ( shelf equipmen As for the outside cabinet, interior temp could easily get a 20 deg C rise from ambient, dependig on wattage and cabinet surface area. Solar loading can also increase it another 20 degrees. A lot will depend on whether enclosure has a heat exchanger, and how efficient it is. So we can expect up to 85 deg. C. A big deciding factor would be where the end user is. Alos if they adhere to the Telcordia Standards/Recommendations. If customer is in North Dakota for Arizona will make all the difference. Perhaps you can have optional enclosure kits for extremes. (Heat exchanger for Arizona models and battery heaters for North Dakota customers. Hope this answers your questions. if if doesn't, or if you have others, let me know, Regards, Eric Petitpierre Pulsecom Herndon, VA
