Installing a T1?

I guess first and foremost, you need to have a few things to do it.


1. The LEC (Local Exchange Carrier) will bring you in a set of 24 lines (ds1/t1e trunk) from there you will essentially need what is considered a "Modem" , formally called a CSU/DSU (Adtran usually makes these units). from there you will need a TRUE ROUTER, ie 2510/2610 Cisco Series Router that can make use of the configuration.

get the CSU sync'd with the t-1, you will need to connect the CSU/DSU to the Router... once you get there someone will need to setup the configuration of the T-1 (ie calling all channels, etc) and pipe it to a local network via NAT... from there if you already have a cable modem in place, hes going to need to have a static route to point the traffic to the lan because the cable modem will be the default gateway...

If you need anymore help, pm me ill be happy to assist

T1's can be data or phone. As far as setting it up that will kind of depend. You will need a CSU/DSU and a router, a lot of times ya end up with a cisco 2600 series router with a T1 WIC card installed. Are you working for the ISP providing the service or just setting the equipment up for this company / person and their getting the service from someone else?

Sometimes the ISP supplys and configures the router at the customer site, and sometimes the customer has to supply and configure it. If you know what equipment you will be using that information would make it easier to help ya out.

Hmmm.....

Do you really need to connect the CSU to a router if your are using layer 3 switches?

Okay, so heres the situation... I know that me and my friend (dathak 512) are setting up a t1 for either a company or some high-end residential customer of the guy were working for.. he already has cable internet so all of the networking and stuff is already in place... all we are doing is upgrading it to a T1...

however, we've never done this before and the person were working for is out of town.. so we might be doing this by ourselves (only knowing very roughly how to do it)

we've both seen t1 systems at the aquarium that we work for in charleston but have never set one up... are we in for a wild ride or a simple setup? He did mention it would only take 20-25 minutes? any help?

This is not meant to insult you but you should call someone who knows what they are doing.
 
If you have a layer 3 switch router (i.e. a switch that does layer 3 routing services) then technically no, but it's a good idea to seperate the LAN routing from the WAN.

you will have your T1 come in
you need to find out from the carrier
1) type of protocol (HDLC, rfame relay, etC)
2) channels (if a full t1 then you dont really need to know which channels)



the T1 will come in to a csu/dsu (which you can get as a module or built into most cisco wan routers, etc if that's what you're going with; as you should) then uplink that to your switched network


it's pretty straight forward, you just need to know how to configure your router.

YES, unless that layer 3 switch has a serial port for interfacing with the modem or has a built in CSU.

no its fine, most everything were capable of this is more or less the stuff that we do at the aquarium... I've just never done it before and wanted to get a little knowledge on what were doing ahead of time... Im pretty sure theres going to be someone else there with us anyway...

the guy were working for is in new hampshire doing some work right now so I know he wont be with us there tomorrow..

Gotcha. Carry on, pay attention and learn something new! Good luck bro!
 
Ooooh kay. #1 Read the telecommunication 101 thread that is stickied.

#2 CSU/DSU are typically the "t1-interface "care that plugs into the cisco router. altho external units are usable as well the WIC's that cisco uses are just fine

#3 Run a T1 cable (pins 12 and 45, or use a straight through ethernet cable either will do) and plug it into the csu/dsu (or the T1 interface card if usinig cisco) Typical settings are b8zs/esf for line encoding and frameing. Thats is. The rest of the configuration will involve setting your ip ranges and whatever else you need.

#4 Read the telecommunications 101 thread. It will introduce you to some common terms you may hear when installing this
