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" .. I need advise .. many thanks in advance

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.
