Hello Dennis, I can't point to a single source of authority on this, but I can tell you from general day to day knowledge in the field that cell sites are linked together in a number of different ways: - ILEC and CLEC leased lines (traditional T1s) - point to point wireless (microwave radio T1s amd T2s) - of course the wireless operators would be predisposed to using this approach at the slightest justification, since it's a lot cheaper and it's right up their alley - over Cable TV operators' fiber links (either DS0-channelized T1s, or, increasingly, over Fast (100Mb/s) or Gb (1,000Mb/s) Ethernet - electric utility fiber lines There has also been talk about the use of infra-red laser links (fiberless broadband, to some) being used to connect cell sites together, but I think that each case would have to be examined closely and individually before commenting on the wisdom of taking this tact. As for references, there may be some articles in Telephony Magazine or OSP Magazine that might be helpful: internettelephony.com ospmag.com ------------ I just did a little scouting around in Amazon.com and came up with what appears to be something you may be interested in: Cellular/PCs Management (Telecommunications) by Paul Bedell amazon.com Check out the table of contents. It's a lot more thorough in the outside plant and transmission departments than the others listed there. The only three reviews in Amazon were perfect scores (5 stars). Has anyone here read this book? FAC
