2 T-1's into a Cisco2800?

[Acoustech]

I'm trying not to outsource this. Can anyone help me get started on what I need to know to get 2 T-1 lines in a Cisco 2800. I noticed this model has 4 Interface slots, 1 of which is already being used by an existing T-1 that we have in our company. I need to order an extra T-1 from a different company and get it load-balanced in this Cisco 2800. Is this possible?

yes, you can order a new set of t1's on both ends.

here is what you need to do;
1. create a loopback interface and move the IP address from the working t1 to the loopback interface

int s1
no ip address
int loopback 100
ip address x.x.x.x 255.255.255.252

2. bind the loopback ip to the t1 int

int s1
ip innumbered lo100

3. purchase another t1 card for slot 2 and copy the same config from serial1 to serial2

4. repeat this on the other end of the circuit.

Thanks for your reply! Should a

do ok for my 2800? Apologies for all the questions, I am trying to read as much as I can to understand this as I have no 'real' hands-on experience with this.

No, that module is not supported.

Check out this list under T1 modules.

If you do not have a full slot available, than you will need to purchase the module with 2xT1 and replace the single T1 module.

I take that back,

If you look at the link you sent, there is a box that list what devices support that module and 2800 is not on that list.

However some of the 2800 docs state that they do support the WIC modules. The best bet is to contact cisco directly.

The WIC-1DSU-T1-V2 is a supported WIC for the 2800 series. I have a 2811 with three of them in it.

Its not that simple.. since you're talking about getting a t1 form a different provider this makes it more complicated.. You would need to own your IP block and be BGP peered to both providers..


I would order another t1 from the same carrier you have now if you don't own your own IP's..
