Multiple E1

Unanswered Question
Nov 16th, 2007

Hai there...need some guideline.

current setup i have 8 branch and 8 E1 line connecting to HQ (4 router which have 2E1 port each).

iam thinking to replace all the 4 router at HQ with only 1 new router.

my question,

what is the best solution, do i need to have 8E1 port on this new router or is there a way i can minimize the E1 port? can i create subinterface i E1 port?

i dont want to use frame relay as i need 2M dedicated lease line to branch.

please do help me TQ

I have this problem too.

You can think about going on for Cisco 2811 or

Cisco 2821 or Cisco 2851 series router with HWIC-4T cards to have your E1 links terminated onto them.

As indicated above, use 2 x hwic-4t with external E1 DSU.

Or, 4 x vwic-2mft-e1 without external DSU.

The other card are not applicable to your needs.
