T3 connection

I need to configure a E3/T3 card in a cisco 3845 router. the T3 connection is from NY to london. As we are based in London do we configure our end as E3 or T3 card and also need to configure framing and line code

Thanks

Re: T3 connection

You should check with the provider who should give you the details of what they will deliver to you. Normally in situations like this the provider will take care of the T3/E3 conversion inside the provider network so that NY will see T3 and London will see E3. But the provider is the one who can confirm the details of this circuit to you.

Re: T3 connection

many thanks I think i have managed to configure this,

I do have another question, how would i find the data transfer rate, i have tried sh int s1/0 command but couldnt seem to find it, The reason I ask is the a file copy of about 1.18gb is looking to take around 193 minutes. just trying to establish trends

many thanks

Re: T3 connection

You should see the standard 5 minute input and output rates as well as the number of packet/bytes send and recieved. Now this is for the complete circuit to find users you will have to get more creative with something like ip cache flow and a little manual calulations.

1.18g in 193 minutes is very slow for a line like this. You must have very high latency. You need to either adjust the tcp window size or break the file into parts and transfer them at the same time.
