This is a pretty good site that will answer most of your questions. http://www.dcbnet.com/notes/9611t1.html On 7/21/04 7:25 AM, "Andre Oppermann" <nanog-list@nrg4u.com> wrote:
I'm having a few questions about T1 line support in the US because I have to procure some Router/Network hardware for US branches of a company (I am from Europe).
Normally in Europe when you order an E1 (G.703) connection the Telco delivers a NTU (Network termination Unit) which normally is a (S)HDSL modem converting from two-wire DSL to four-wire E1 electrical. The cable between the NTU and the Router is normally very short, a few feet/meters.
o How is this normally done in the US by the Telcos for T1 lines?
o I assume the difference between T1 short-haul and long-haul is the cable length. But what is it used for? Is it still common to have long-haul T1 connections either within buildings or towards the central office of the Telco? Would I be fine with buying short-haul-only interfaces in any common scenario?
o What is "Wet T1 Capable"? What is it used for and who needs this?
o What else is important in dealings with US Telcos when ordering and using T1 leased-line services?
Thanks for any input.
