SE equipment right after Covad DSLAMS ?

Can anyone help me with the name of the SE equipment that comes right after the Covad DSLAMs?

The Covad guy told me the other day, and now I forget. I wanted to read up on it.

The Covad DSLAM that I work into is in Mech, PA. Covad sends all that DSLAM info to their Harrisburg, PA equipment. From there, they trunk the DSLAM signal up to NY state, where the SE equipment is located. When I ping, I'm pinging the SE equipment up in NY state.

Can anyone tell me who makes SE's equipment that I'm pinging into? I can't remember the name of the equipment that the Covad guy told me the other day. I think it starts with a "P".

I am not 100% positive but I believe Speakeasy uses Juniper equipment.


The Covad guy told me a couple days ago. If I heard the name, I would remember it.

Come to think of it. I think it had the name "Red" in it...rather then a word that starts with a "P".

I think it may have been the trade name of the equipment.

I remembered it. It's "Redback".

Only problem is I'm not quite sure what a Redback it...lol.

I think it must be some kind of SE router.

I'm wondering if their Redback router is what is causing my dsl light to go off on my dsl modem at times ?

Speakeasy has published a white paper on our network architecture, located here:

The information you're asking for is specifically documented on page 15 of the white paper.

Basically, the last mile connectivity (supplied by Covad, New Edge Networks, Qwest, AT&T, etc. depending on your location and subscribed service) from your location to the Central Office is connected directly to a DSLAM (DSL Access Multiplexer). For lineshare ADSL, additional components such as voice/data splitter cards exist at the CO as well.

Once the traffic is terminated at the DSLAM, it's aggregated to an ATM circuit (DS3, OC3, etc.) by our vendor to their BPX within their ATM network.

The handoff from our vendor to Speakeasy occurs on a DS3 or OC3 referred to as a backhaul. Most of our Points of Presences (POPs) have multiple backhauls, often a combination of DS3's and OC3's to haul our customer's traffic to our POP.

Once you're at the POP, our edge router handles the subscriber piece of the equation, hands the traffic off to our core router, which routes your traffic through our private network, to a peering partner or out to the Internet.

The white paper does a much better job of elaborating on the details, but this should give you a start.

More information on our network is available at:

Hi Adam:

Wow. Very good information.

I'm not getting the longer intermittant outages that I use to. Most of the time it is about 5 to 10 seconds. I use a pinging program to tell me the time of day it happens. I just don't know if it is happening due to the copper line I have or something else up to the Redback router.

The Covad guy was out at my place and did notice he was getting different distance readings, so he opened up a trouble ticket with Verizon. I'm hoping that might be the problem.

Thats why I was trying to learn more about the architecture. That paper you linked to sure is great. Sounds like you really know the technical setup real well.

I'm waiting to see if I can get my dsl circuit more stable. If so, then I want to get another SE dsl circuit for a client of mine, who wants me to set up a WISP in their neighborhood.

Thanks Adam, that is a great document.

FYI there is a typo on page 7, the reference to »www.lg.speakeasy.net doesn't work, I found that it does work if I remove the "www", e.g. »lg.speakeasy.net/
