If you are hooking up T1 service at your office... what is a dataport and what is it used for?

Talk to the T1 provider. They will explain.

Some other points to add, this really belongs in the Network forum, its not really a begniners question. I also question why a T1. Generally you can get the same performance and easier management with a business DSL line for a lot lower cost.

P.S. To Need, you got to learn to be succint in your answers you types almost 3x the characters ;)

A T1 installation is usually not user-installed. There are many differents types of csu/dsu or modems that are used. Best to call your provider.

Basically there are two sides to a T1. The side that faces the provider and the side that faces your network. The side that faces your network is the data port. Usually if you only have a CSU/DSU then you'll get what looks like a telephone cable from the provider and then another V.35 cable (sometimes db25) cable (your dataport) goes into the serial connection on your router. Now-a-days you can get a router that has a CSU/DSU built-in so all you have to worry about is the connection to the provider and a connection to your local ethernet.

If you have no idea what this all means then I'm with NeedKarma. Have someone that knows what they're doing set this up for you.
