Message-ID: <XnsA0BDD2DBB167nospamnospaminvalid@220.127.116.11> I currently use a Samsung SGH-747 cell phone on the ATT network. It has a 3G SIM card. If I get a Samsung Galaxy S3, will the Galaxy's 4G (LTE) SIMM card work in the SGH-747, if I need to use the older phone sometime as a backup? Thanks. *Moderator note: the basic info in a SIM is stored in a standard, phone- independant/brand-independant, manner. But there is also provision for 'private' supplemental info. For a truely authoritative answer, you'l probably need to check with AT&T, or Samsung.

Truckers doing that aren't yakking on a phone -- they're dozing off (!). Cheers, -- tlvp -- Avant de repondre, jeter la poubelle, SVP.

First thing to consider is the fiber drop cable itself. Most OSP cables are not intended to be installed indoors, because of flammability, horizontal/vertical flame spread potential, and toxicity of the smoke when burned. I believe that the NEC at one time did permit a certain maximum amount of drop cable to extend within the building - consult the latest revision for details. Some drop cable is rated for indoor/outdoor use, but I doubt that the V. installer will have any idea whether their drop cable is or not. Second, grounding is an issue. Nobody believes this, but the FiOS ONT is intended [read: Required] to be properly bonded to the same ground as the electrical service entrance of the building. There are reasons for this - such as the fact that all the coax cable in the building is ultimately terminated to the ONT. The outer braid of the coax wants to be grounded for safety reasons that go beyond the scope of this thread. Also, some fiber drop cable has an embedded metallic strand for strength. This strand is absolutely required to be bonded per the NEC. In order to properly bond the ONT to the electrical service entrance ground, it should be located in close enough proximity to allow for a short, straight run of the bonding conductor. There seems to be a lot less emphasis these days on code compliance and such where Telecom is concerned, but I am willing to be a lone voice in the wilderness. Sorry for dredging up a thread that is more than a week old... Jim Bennett ================================================== Speaking from a secure undisclosed location.
