can a 10 Base-T 4 bonded t1's

[stvleaze]

Simple question.
Will a 10 Base-T port on a router be able to handle 4 bonded t1's?

Is 10 Base-T 10mb up and down? Like a T1 is 1.5 up and down?

I guess what I am asking is, if 4 T1's (6mb up/down) was maxed out. This would be 12MB of traffic.

Would that 10 Base-T be up and down? Or 10MB TOTAL up and down shared?

A single 10BaseT port (10 Mbps, half duplex) would melt under those conditions. That bandwidth is shared between incoming and outgoing sources. If you have a lot of bidirectional traffic, the port probably won't be able to handle more than 4 Mbps or so.

If the interface can be configured for full duplex then you have 10 Mbps each direction. Even then, the interface could not handle the traffic if you were trying to aggregate the traffic from four T1s that were maxed out.

HTH,

What you really need to think about is this... a router with a 10baseT port most likely has a really slow processor..

If you're really going to nail 4 T1's with traffic, that will kill any router that you are probably looking at..

That's another excellent point. You need a pretty beefy router to drive that many T1s. For example, even one of the new 2811 ISRs can't drive more than two T1s at line rate, and those are pretty decent routers.

It is a 3640 Router. It does not come with built in ethernet.

I have a 10 base T ethernet module laying around though.
Sprint says they can do up to 6 bonded T1's.

I was going to max out the router with full memory. And install 6 wics in it. (Only use 3 for now)

Then it looks like I will need a 100mb ethernet module also.

Will the 3640 be able to handle 6 t1's in MPPP?

Get a one of a NM-1FE-2W. 1-port fast ethernet module with 2 wic slots. Or at least 1 NM-1FE-TX.

 

[baddos]

The 3640 comes with a built in Fast Etherenet port which is capable of 100Mb Full Duplex.

You sure about that? The old product guide I have shows that the 3640 had 0 fixed ports other than the console and aux ports. Everyting for that router was module based.

It does not come with built in ethernet.
It is module based only. The 3660 has one bulit in though.

So will a 3640 maxed memory with a NM-1FE-TX be good for up to 6 bonded T1's?

I think what you really need to look at is the thoughput specs for the router. The interfaces can do it no problem and it can be configured but if as jneiberger has said is true then the throughput is what you need to consider.
