:tazz: What is the difference between a shared data T1 line and a full T1 line? I know that The shared data T1 is usually run to an MTU (multi-tenant unit) and split up into separate data networks for tenants that choose to use the Internet service. But isn't that the same thing as a full T1, can't you share data ona full T1? The ISP I work for (Rock River Internet) sells T1 service in three diff. ways: full T1, Shared data T1, and protected T1, I know what the other two are but I'm not sure what the difference between the first two are. We don't sell fractional or burstable T1 so I know shared data T1 isn't the same as those. I guess I'm just confused... :)

IS this the same thing as a shared data T1? A channelized T1 contains 24 individual channels, each capable of carrying voice or data. The full set of channels has the same speed as a full T1, but the individual channels may be split into voice lines or data lines using a device called a Channel Service Unit/Data Service Unit or CSU/DSU. The CSU/DSU is used to split off the voice channels from the data channels, allowing the voice channels to be connected to a phone system or PBX. The data lines are then connected to a router serial interface and often are used to provide Internet connectivity??? SO is the difference really that a full T1 you can't split the channels but a shared data T1 you can?

i would say that your second deffinition is probably on the right track...i've nevere heard of a "shared t1" just full or fractional...which sounds like a completely different setup (full t1..you get the whole pipe...fractional you just get a few channels of the pipe)...i'll do some research

http://www.rockriver...ces/shared.html found this...it's an isp's listing of what they provide as far as the shared t1..but it's a decent explanation...apparently a shared t1 would be used..(from what i can gather) by a bunch of business that work in the same building (like an office complex or something like that) but aren't really the same business...they would pool together their resources and get a shared t1 as to save cost (as each individual will not have to pay for the t1..they can just split the cost)...the T1 channels would be split by the ISP or telco by the MTU (multi tennant unit) according to how the companies want it set up...this would be different than a full t1 in this situation in that if these companies wanted to get a standard full t1...they themselves would have to manage the seperation of service...which would be virtually impossible as i don't know of a way for an individual to split the channels on a provisioned t1..so basically...if they went with this..they would all have to be on the same network...or at least have their router managing all networks involved which would allow for cross traffic, companies getting their hands on each others documents, n etwork intrusion, shared virus infections...and stuff like that.....so i guess...when managed correctly....a shared t1 is a way of setting up the connection so that multiple seperate entities in the same geographical location can share resources safely as well as sharing costs
