Aggregate E1 links

If we have a case with 20 remote sites, Each remote site has two E1s links, and i need to aggregate these links into Cisco 7206VXR Router, i think i can do that by ordering 3 PA-MC-E3 adapters since each adapter can carry up to 16 E1s and i think that we can divide each E1 link into this adapter by a channel-group. Is this design and configuration right? Or i can order two PA-MC-T3 in order to aggregate these E1s into this two T3 adapters?

Thanks in advance

Re: Aggregate E1 links

You being in Europe or the Middle East (E1s ...) T3 is not an option for you. So you will have to go with the PA-MC-E3.

Why dont you look at the channelized STM-1 module. It can aggregate upto 63 E1s. The only concern will be increasing the module failure impact. Since you have two links from each site, which is probably for redundancy purposes, I believe you should look at aggregating these on separate routers (two 7206s) if you are not doing so already.

Re: Aggregate E1 links

Hi Atif,

Thank you for your response.

Look, this copper access (E1s) will be redundant for main Fiber access. I alreacdy used Cisco 6506-E to aggregate Fiber links and the Cisco 7204VXR to aggregate E1s. I will check about channelized STM1-module. About two Cisco 7204VXR routers, you are right to be each line connected to one of these two routers for redundancy, but i thing budget concern.

Anyway, thanks alot

Re: Aggregate E1 links

Hi Hajhamad,

The easiest thing you can do to bundle up all the E-1s together is to use PPP at the L-2 and then use the Multilink Feature of the PPP.

I'm sure that will help your case.

Wilson Samuel
