What is this research for? There is alot of information available, however depending on location you may not be able to get some of the equipment. There are many different types also, are you providing from an ILEC point of vue, are you doing a COLO through a CLEC. What type of service are you going to provide. WI-FI? DSL or cable modem, they are similar yet all are different in deployment. Need more specifics.
