Move from F/R to E1 leased line 2Mb channel

[Winan]

Dear Expert,

Currently we have 4 Frame Relay connection to branches (A (as HO) to B,C,D,E), we plan to move to E1 leased line 2Mb channel from A to B,C,D,E my question is: is it necessary for me to buy some peripheral ?, below are what I had when "show version"

Are you saying that you're replacing your frame relay network with four point-to-point circuits? If so, do they all terminate back at "A"?

 

[Winan]

in F/R - A (Head Office) as backhaul, I don't think it's same with E1 leased lined channel.. any comment or idea?

 

[jneiberger]

That's what I'm asking you! This is your design, I just want to know how you're doing it. Are you planning on having your point-to-point circuits terminating at "A", or are you planning on doing it differently?

Why are you moving away from frame relay?

 

[burtsbees]

I think he is saying that he wants four separate E1 circuits, all from A to B, A to C, A to D and A to E---I say he has only 2 serial interfaces, and I believe he is asking if he needs more peripherals, meaning serial cards. Well, it looks like you need 2 more serial cards. Are you trying to ultimately incorporate a MLPPP bundle with the four E1 circuits? Thanks.

[Winan]

Thanks, I plan to move from F/R to E1 because of speed issue, as we know that F/R using CIR and E1 is dedicated lined.

and Ye, A is HO, all branches should have Point to Point to HO

 

[jneiberger]

Ah, if that's the case then you need two more T1/E1 high-speed serial interfaces on your 3640 because you'll end up with four E1 circuits.

 

[Winan]

you meant NM-4T?

 

[jneiberger]

Yes, an NM-4T would work.

I replied to your duplicate post....


The remote offices should be ok since they prob already have E1 cards in them from the current frame connection. They are probably connected to the main office with fractional E-1's running 512cir?

The main office may be an issue though... It prob only has one E1 interface right now running frame-relay with a CIR of 1 to 2 megs.

Can you supply a bit more info regarding your current setup? Maybe a show run that shows the serial interfaces.
